Here’s a short and to the point tutorial teaching how to Bass Boost your songs with Audacity. To download Audacity for FREE you can go to the official Audacity website here – http://audacity.sourceforge.net/ You may want to Bass Boost your songs for many reasons, so here’s a tutorial on how to do just that with the popular, Free, and easy to use software called Audacity.

Step 1: Download Audacity

The first thing you want to do if you haven’t already, is download Audacity. Again, Audacity is completely free to download and use so here’s a link to their website – http://audacity.sourceforge.net/

Step 2: Import Your Song Into Audacity

Now you must import your desired song. To do this just click “file” then “open” and select the song or sound that you would like to boost the bass of.

Step 3: Normalize the Song

Next, open up Audacity and click the effects tab. A drop down menu will pop up. From the drop down menu, find the setting called “normalize”. Click normalize and a small window should pop up. It will give you the options to how much you want to normalize. The best setting for this is between -9.0 and -15.0. If these levels don’t fit your needs, adjust until you get the desired level and click “ok”. The waves should now appear smaller than they first did when you imported the song into Audacity.

Step 4: Adjusting Bass Levels

Now to boost the song, click the effects tab again and click the “Bass and Treble” setting. This will open up another smaller window in Audacity giving the options to adjust the bass and treble levels. Keep the treble at zero and adjust the bass until it fits your needs. You can always click the preview button to make sure your’e satisfied and then click “ok”.

Step 5: Exporting Your Bass Boosted Song

Now on to exporting your new sound file. To do this go to “file” and then “export”. Choose your desired format and click “save”. Another small window will pop up so just click “ok”. This will save your new bass boosted sound file! Now you can close out of Audacity and listen to your new improved song!

Bass (dB)

The amount of gain (amplification above 0 dB or attenuation below 0 dB) to bass (low) frequencies. Set this to a positive amount to boost the bass, or to a negative amount to reduce the bass. Bass gain is applied to frequencies lower than 1,000 Hz, with the most gain being applied to frequencies about 100 Hz or lower.

Treble (dB)

The amount of gain (amplification above 0 dB or attenuation below 0 dB) to treble (high) frequencies. Set this to a positive amount to boost the treble, or to a negative amount to reduce the treble. Treble gain is applied to frequencies higher than 1,000 Hz, with the most gain being applied to frequencies above 10,000 Hz.

Volume (dB)

This increases or reduces the overall level by up to +/- 30 dB.

  • Applying a boost to the bass or treble will tend to increase the overall level. As a result, the final level may be pushed so high that it distorts (clips). To avoid clipping, reduce the level by setting the Volume control lower.
  • Reducing the bass or treble may make the final level too quiet. To compensate for the lower level, set the Volume control higher.

Link Volume control to Tone controls

When this is enabled (checked), adjusting either the Bass or Treble controls will automatically adjust the Volume control so as to lessen the change in the resulting output level approximately the same.

Technical details

Bass and Treble is a two-band Equalizer.

  • The Bass control is a low-shelf filter with the half gain frequency at 250 Hz.
  • The Treble control is a high-shelf filter with the half gain frequency at 4,000 Hz.
  • All slider controls have a gain range of +/- 30 dB.

Buttons

Clicking on the command buttons give the following results:

  • Manage gives a dropdown menu enabling you to manage presets for the tool and to see some detail about the tool. For details see Manage presets
  • Start Playback starts playback of the effect preview
  • Skip Backward skips backward through the effect preview
  • Skip Forward skips forward through the effect preview
  •  Enable listen to the preview with or without the effect applied
  • Apply applies the effect to the selected audio with the current effect settings
  • Close closes the dialog brings you to the appropriate page in the Manual, this page

Real-time preview

This effect supports Real-time preview – effect settings can be changed while playing and listening to the result in real-time. Text-based button controls are provided as in the image above. The Enable checkbox acts like a live “Bypass” control. Uncheck the checkbox  Enable to hear the audio without the effect applied, and recheck the box  Enable to hear the effect applied at its current settings.

The Manage button accesses choices to add, delete, import or export presets for this effect and to set options for this effect. For details see Manage presets.

Clear Audio is something that makes a video 10 times better. I don’t enjoy or like a movie whose audio is not so clear (I’m not talking about pirated movies😉). If you have a small business and you want to do Voiceover instead of buying an expensive microphone, you can simply use this tutorial. A lot of people are willing to pay money for a better voice, now you can do it to your voice. So, let’s take a look at how we can edit audio using Audacity.

Before the exciting stuff, let’s get to know more about the software and How you can download it.

What is Audacity?

How to adjust bass in audacity

Image: Audacityteam.org

Audacity is free and easy to use multi-track audio recorder and editor for macOS, Windows, Linux/GNU. The software is available in any language, so you don’t need to worry about only using it in English. An audacity is an open-source software like Firefox, LibreOffice, and OpenOffice which means the source code is available for anyone and everyone to use. So if you are interested in looking into the code, here is the link.

Here are some of the Audacity features:

  • You can record live audio
  • You can convert tapes and records into CDs
  • You can open and edit WAV, AIFF, MP2, MP3, FLAC sound files
  • You can mix the sounds
  • you can Copy and Cut Sounds
  • You can apply tons of effects to your sound
  • You can also write your plugins

Enough of this, let’s dive right into our Tutorial and learn how to edit sounds. One thing to remember, there are many ways to edit a sound in Audacity. I will teach you one of the easy and effective methods. You will love it once we are done with it.

Let’s get Started

Download the software and open it. Once you are in the app, you can start recording or open an audio file. I recommended recording in the App.

Once you press the recording button, start speaking after 5-6 seconds. The reason is, we need to remove the background noise and that 5-6 seconds allow us to apply some effects. Check out the photo below, that’s how your recording should look like.

How to adjust bass in audacity

The next step is to remove the background noise. Sound like fan noise, people talking in back, AC noise, etc all extra sound will be gone in our next trick.

How to adjust bass in audacity

Select the first 5 seconds as shown above and click on Effect->Noise Removal and click on Get Noise Profile. Now, double click on your audio recording that will select the entire recording. Then, go on Effect->Repeat Noise Removal. That will remove your Background noise by 90%.

The next step is to Compress the Audio. Make sure your audio is selected(double click on Audio to select) and go on Effect->Compressor and change the Threshold to -18 dB. The more you drag towards the left, the more background noise you will get. So keep it around -18db to -20dB. This will bring up your Voice and Vocals.

( Skip this step if you are female ) Keep the audio selected. Now, we will apply some bass to our recording. It helps to make you sound deep. Go to Effects->Equalization, you will see a drop-down menu right next to Select Curve. Change it to Bass Boost, see the photo down below for help.

( Skip this step if you are female ) Now, we will repeat the last step. But select a different menu this time. Go to Effect->Equalization, you will see a drop-down menu right next to Select Curve. Change it to Treble Boost. Because we select Bass Boost, we also have to apply Treble Boost. In simple language, Bass Boost brings your sound down and makes it more manly so to make it pop up we have to apply Treble Boost. See the image below for help.

The next step will level off your sound. Because you are sometimes too loud or sometimes too quiet, it will normalize your sound. Select the entire recording by double click, Go to Effect->Hard Limiter. Change the dB limit value to -4.0 (Keep it between -2.0 to -5.0). You might have to tweak it, depending on how loud you talk. I recommended you keep it at -4.0.

The last step is to Normalize it one more time. Select the entire recording by double click, Go to Effect->Normalize and click Ok. You don’t need to change any setting, just keep at its default.

That’s it, you made it to the end. You become a pro-voice-over just by spending 3-4 minutes editing your Voice. You don’t need to spend more money on voiceover and you can create your own.

Introduction: How to Improve Vocal Quality in Audacity

What is Audacity?

Well, Audacity is a FREE audio editing & recording software. If you don’t have it already, grab it HERE.

How will Audacity help my vocal quality?

By following this simple Instructable, you will soon find out how to vastly improve your audio in a few minutes

Step 1: Recording Your Audio

How do I record?

Simply click on the record button and it will begin to record your voice, make sure you have your microphone plugged in.

What should I say?

Wait a few seconds before and after your recording. It doesn’t matter what you say, I normally say “Test 1. Test 2. Test 3” just remember that after you have recorded the audio you press the stop button (orange square.)

Step 2: Removing Background Noise

How do I do this?

Highlight the blank audio at the beginning of the recording, you should’ve noticed that there is some static/buzzing sound. Then click Effect: Noise Reduction: Get Noise Profile. Once you have done that, highlight the rest of the audio and press Effect: Repeat Noise Reduction. Make sure you have the whole track selected befor you repeate noise reduction.

What is a ‘noise profile’?

A noise profile is just a few seconds of audio that Audacity will filter out, it is important not to highlight anything other than the beginning noise otherwise Audacity will filter out that as well.

Step 3: Compression

How do I do this?

Click on Effects: Compressor, and keep the settings on about:

Noise Floor = -40db

Attack Time = 1.81 secs

Release Time = 11.1 secs

What does compressing the audio do?

It will bring up your vocals so that if you are talking too quite it will make you louder, this is very useful for people withe low quality microphones.

You may need to mess around with the compressor’s settings, just keep in mind that the further left you move the threshold, the more background noise you will hear. Try to keep the threshold around -15 to -18.

Step 4: Bass & Treble Boost

Why is this step important?

By bass boosting your voice, you are making it sound more deep/manly, so if you are a girl, I suggest you skip this step. But this step is important as it will help with the quality of the audio, this step can also be used for bass boosting music. By treble boosting your voice, you are making it stand out more, this step can still be done by girls if you want, I just suggest that unless you want a more deep/manly sounding voice, you don’t bother bass boosting.

How do I do it?

Go to Effects: Equalisation, select ‘Bass Boost’ from the dropdown menu and press OK. Leave the setting as 9db. Repeat this step again, but this time select ‘Treble Boost’ from the dropdown menu.

Step 5: Limiter

A limiter is just something that limits the maximum db rating, so if you speak too loudly and then too quietly you can prevent clipping.

How do I do this?

Go to Effects: Limiter: select Hard Limiter from the dropdown menu. I prefer to leave the maximum db rating as 3.00db, you can change this rating.

Step 6: Normalise

What does this do?

It just makes your voice louder.

How do I do this?

Go to Effects: Normalise: leave it as default.

Step 7: Remove Blank Audio

Is this necessary?

No, not at all. It just shortens the length of the file and makes it easier to add to background footage for a gaming video, commentary etc. If you do remove the blank audio, I would recommend not to delete all of it. This is just so you don’t risk deleting any audio by accident.

Step 8: Enjoy!

You now have nice, clean sounding audio for your videos. Make sure to share this Instructable with anyone you know that is interested in learning how to make their audio sound better for gameplays and videos!

So you want to improve your voice quality on your next audio project? Chances are, you’ve had a scout around the internet, and have stumbled upon some nifty audio software called Audacity.

Audacity is an easy-to-use and completely free multi-track audio editor and recorder for Windows, macOS, GNU/Linux and other operating systems. It’s great for audio recording and podcasting.

If you’re overwhelmed at what this audio software can do, don’t be! We’ve compiled a handy list on how to improve your audio projects using Audacity.

Whether you’re a podcaster, a sound recordist, or simply someone who wants to sharpen up some audio you have, look no further than this guide on how to improve voice quality.

#1 Use the Noise Profile

Firstly, it’s important to clear any background noise. To do that, you just need to understand what frequencies you want to remove. Audacity’s Noise Profile will do just that. Click Effect> Noise Production, and then select Noise Profile. This means you can analyse the audio section and see exactly which frequencies you need removing.

#2 Use Noise Remover Next, it’s time to remove the noise – but hopefully you won’t have much. Select the entire section of waveform from which you want to reduce the noise, then set the Noise Reduction parameters. Use trial and error, adjusting the sliders and listening as you go along.

You can also use Krisp to remove noise, a simple and easy tool that seamlessly works with Audacity to remove background noise. What’s more, it works in real-time, meaning the noises are removed during your audio recording.

So there’s no need to go back and delete the noise when you use noiseless recordings using Krisp with Audacity. After you download and install Krisp, configuring with Audacity is a piece of cake.

Hover over the audio settings in Audacity and select Krisp microphone. Then let it perform its noise cancelling magic. Simple!

To listen while Audacity is recording, enable what is known as software or hardware play-through. If you use software play-through and want to listen to the input without recording it, you need to also left-click in the Recording Meter Toolbar to turn on monitoring.

#3 Use the Normalizer

The Normalizer feature in Audacity is the next best shout for improving voice quality on your audio recordings. Immediately after recording capture (or import) of your audio, this effect should be used solely to remove any DC offset that may be present with no amplitude adjustment applied at this stage.

Use the Normalize effect to set the peak amplitude of a single track, make multiple tracks have the same peak amplitude and equalize the balance of left and right channels of stereo tracks.

This will ensure your podcast or audio recording has that all-round audio goodness when listened to through headphones.

#4 Use the Compressor

Compressing the audio is used for increasing the volume of your vocals so that if you are talking too quiet, it will make you louder. As you can imagine, this is particularly helpful for podcasters with low quality microphones.

Here’s how to do it:

Click on Effects: Compressor and keep the settings on the following levels:

Noise Floor = -40db

Attack Time = 1.81 secs

Release Time = 11.1 secs

Don’t be afraid to play around with these settings to get the volume just right. If you move the cursor to the left, you’ll hear more background noise.

It’s important to keep the audio level out of the red (below 0db), as this can cause distortion. Use the level control to turn it down if this occurs.

#5 Use the Equalizer

So, another cool Audacity setting is the Equalizer. It’s a tool for manipulating the frequency content of sounds, it allows you to set the

balance between the low, mid, and high frequencies. Understanding how these work will make a huge difference to your audio quality.

In women, the frequency range is about 165 Hz to 255 Hz. In men it is a bit lower, 85 Hz to 155 Hz usually. This gives you a more specific range to tinker with it so you don’t put a ton of time and effort into ranges that really don’t affect voice quality.

Use the preview button to monitor the settings and tweak until your Audacity fle sounds clear. Usually a slight dip to the low end or a slight boost will make the world of difference. Once you’re happy with the sound, click “OK” to save changes.

#6 Use Spectrogram

When analysing your audio quality, you want to make sure that you’re looking at the best possible dashboard in Audacity in order to edit your audio effectively.

The Spectrogram view of your audio track provides a visual indication of how the energy in different frequency bands changes over time. That means it can show sudden onset of a sound – making it easier to see clicks and other glitches. It’s also better to use this view for lining up beats in this view rather than in one of the waveform views.

#7 Use The AutoDuck Effect

Have a podcast and you find that sometimes your background music or jingle can drown out your voice? Yeah, you don’t want that.

Try using the AutoDuck to improve the voice quality of your audio project. This Auto-Duck effect is inbuilt into Audacity.

It uses a ‘control’ track to lower the level of the ducked track. That means that when the music is playing at full volume, it will detect when the narrator starts speaking. Clever, right?

This then lowers the level of the music track so it is quieter than the narrator. When the narrator finishes, the music returns, or releases to its original level.

#8 Use Bass And Treble Boost

Finally, you can always utilise the trusty bass and treble boost buttons on your Audacity software. The Bass and Treble functions increase or decrease the lower frequencies and higher frequencies of your audio independently. They operate just like the bass, treble and volume controls on a domestic stereo system.

Things to remember when using this function:

  • Applying a boost to the bass or treble will tend to increase the overall level.
  • Reducing the bass or treble may make the final level too quiet.
  • If both the treble and bass frequencies are increased and the overall volume lowered, the overall effect means there’s a reduction in the middle frequencies. Similarly, reducing both the bass and treble and increasing the volume has an overall effect of boosting the middle frequencies.

Combine Audacity and Krisp for the perfect audio production

Audacity is an ideal program for achieving a better professional audio recording of your voice, especially if you’re a podcaster.

Try Audacity for your next project, but be sure to install Krisp so you don’t spend many hours going back and removing all the background noise!

Used Audacity and Krisp together to improve your voice in Audacity? We’d love to hear your finished results!

This Instructable will show you how to generate a sequence of drum beats in Audacity which can be mixed with other instruments.

Step 1: What You Will Need

You will need:
A computer capable of running Audacity (Linux, Windows, or Mac)

A set of drum sounds (Included as ZIP file with this Instructable)

Attachments

Step 2: Installing

Make sure Audacity is installed. Then extract seq2.zip which you have downloaded from (http://wiki.audacityteam.org/wiki/Download_Nyquist_Plug-ins) and copy seq2.ny into /usr/share/audacity/plug-ins/ if you use Linux
OR
C:/Program Files/Audacity/Plug-Ins if you use Windows

Extract 17-29_TicTacShutUp_Studio_Drums_1.zip . It does not matter where the drum sound files are placed as long as you can remember where they are.

Step 3: Import Drums

Open Audacity. Under Effect. Plugins 1 to ?Audio Selection Sequencer Two” should appear. Next, Import the drums you would like to use by clicking on File. Import. Audio. Each drum should be a different layer/track. You may wish to label the tracks by clicking on the down arrow beside the track, then name, then type the name of the drum (eg. bass drum) All tracks should be mono. Double click the track to select it and then click Tracks. Stereo Track to mono. Do this with all the tracks. Remove any unwanted audio by highlighting and then pressing Delete but be careful not to remove too much.

TIP:Be safe, save often.

Step 4: Sequence

Double-click to select the first drum track. Then go to Effect. Plugins 1 to ? . Audio Selection Sequencer Two. Enter a tempo. Beats per sequence should be “4“. Overall Transpose Value, then for successive measures should be “0“. Sequences to generate should be “1“. Type in the semi-tone volume pan (SVP)values, these will be the drum pattern.

(0 1 0) is a hit
() is a rest
therefore “(0 1 0) (0 1 0) (0 1 0) (0 1 0)” is constant hitting

Create patterns for the other drum layers.

Step 5: Finishing Up

Adjust the volume levels of the individual tracks if needed by clicking on Effect. Amplify. Negative amplification will lower volume levels. Positive amplification levels will raise volume levels. Avoid clipping. That’s it, have fun!

I have attached MP3, OGG and Audacity versions of a drum sequence I have generated. The OGG version will play directly in Firefox.

Audacity – open source audio editing software – is a great choice for podcasts, recording home workouts, even lesson notes. You can use Audacity to record on your computer and refine voiceover for video projects, even "reaction videos" on YouTube .

Audacity Audacity for Mac

Audacity is quite "good" in the field of sound effects, but not everyone knows how to create or make the most of this feature. The following article will provide tips and how to create unique audio effects with Audacity .

How to adjust bass in audacity

How to create unique sound effects with Audacity

Create sound effects like phones

Want to create sound effects as if it came from a phone or need a foreign voice? To do this, select the audio you want to edit, then open Effects> Equalization . Here, go to the Select Curve box and select Telephone . Wait for a while for Audacity to apply the effect, then listen again.

The video below perfectly illustrates this process. Note that other effects are available in the drop down menu.

Play radio as environmental sounds

Are you planning to produce an audio play or short scene? You need a bit of ambient radio sound to delineate the relevant location (for example a kitchen or car) by broadcasting the radio.

To apply this effect, once again, select the desired audio track, then Effect> High Pass Filter . Here, set the Rolloff drop-down menu to 12 dB , then click OK . Wait a while to apply the effect, then go to Effect> Amplify> click OK for the default option.

Next, go to Effect> Low Pass Filter and set 6 dB for Rolloff . Now we need to go back to Effect> High Pass Filter> choose 6 dB for Rolloff> repeat Effect> Amplify setting with the default option. Finally, return to i Effect> Low Pass Filter and select 12 dB .

Throughout the process, keep checking the audio through each stage to make sure you like the effect or maybe want to tweak the final amplification. You can also add white noise noise to the radio sound by adding a new audio track ( Tracks> Add New> Audio track ), then selecting Generate> Noise . > click White .

Handling white noise effects similar to the first audio file, including amplification and filter changes. Watch the video below to better understand:

Devil's voice

Need to put some kind of evil, evil sound in your product? You are making some voice for a video game mod project or radio (like what you can buy on Audible) . In fact, you can use Audacity to create that effect.

This job is very simple. Start with three identical tracks (duplicate the first one by selecting and pressing Ctrl + D ) then rename them if desired. Next, adjust the gain on the second and third tracks, then change the pitch. Do this by selecting the track, opening Effects> Change Pitch and setting the pitch for track 2 to -5 and pitch for track 3 to -25 .

Do the same with the next effect, select track 2> open Effects> Echo and change the delay to 0.1 , then click OK . You should listen to the track again 2 times. Go to Effects> Gverb , leave the settings as they are and click OK .

After selecting track 3, open Effects> Bass Boost and set Frequency to 200 , Boost to 16 , then click OK .

Sounds like a robot

You can handle robot-like voice with Audacity. Similar to the devil effect, you can create it in just a few minutes.

Start with the phrase you want to robotize. Copy it with Ctrl + D . Select the second audio file, open Effects> Echo and set the Delay time to 0.04, Decay to 0.6, and then click OK to confirm the change. Next, select this audio file again, go to Effects> Change Pitch > set the Percent Change percentage change to –10.

Return to the original track, press Ctrl + D to repeat it again. Select track 3 and open Effects> Change Tempo , set Percent Change to -3. Click OK to confirm. It's done. However, you may want to tweak all three audio files to get the desired robot voice.

Remember robots don't talk like humans. Whether you are trying to impersonate Microsoft Sam or JARVIS in Avenger, you need to adjust the way of speaking to work.

Daleks voice effects

This is a video describing how to use Audacity with the Killeringer plugin to create Dalek voice effects from the Doctor Who movie of BBC America.

Basically, Audacity simulates the homogeneous bell modulation effect, developed in the 1960s. If you are a fan of this movie, this method is extremely useful.

Laser sound effects

This effect begins with a drum piece created by the Chirp effect. You will find it in Generate> Chirp . Set Waveform to Sawtooth, with the Start Frequency starting at 1200 and the End value at 50 ; set Amplitude to 0.7 in both fields.

Access Linear in the Interpolation drop-down menu , set the duration to 00,200 seconds, then click OK . As a result, you will get a laser-like sound effect in the 1980s. Watch the following video to better understand.

Above is a guide to creating special sound effects with Audacity . Hope the article is helpful to you.

How to adjust bass in audacity

Accessed by: Effect >Bass and Treble.

Bass (dB)

The amount of gain (amplification above 0 dB or attenuation below 0 dB) to bass (low) frequencies. Set this to a positive amount to boost the bass, or to a negative amount to reduce the bass. Bass gain is applied to frequencies lower than 1000 Hz, with the most gain being applied to frequencies about 100 Hz or lower.

Treble (dB)

The amount of gain (amplification above 0 dB or attenuation below 0 dB) to treble (high) frequencies. Set this to a positive amount to boost the treble, or to a negative amount to reduce the treble. Treble gain is applied to frequencies higher than 1000 Hz, with the most gain being applied to frequencies above 10000 Hz.

Volume (dB)

This increases or reduces the overall level by up to +/- 30 dB.

  • Applying a boost to the bass or treble will tend to increase the overall level. As a result, the final level may be pushed so high that it distorts (clips). To avoid clipping, reduce the level by setting the Volume control lower.
  • Reducing the bass or treble may make the final level too quiet. To compensate for the lower level, set the Volume control higher.

Link Volume control to Tone controls

When this is enabled (checked), adjusting either the Bass or Treble controls will automatically adjust the Volume control so as to lessen the change in the resulting output level.

Technical details

Bass and Treble is a two-band Equalizer.

  • The Bass control is a low-shelf filter with the half gain frequency at 250 Hz.
  • The Treble control is a high-shelf filter with the half gain frequency at 4000 Hz.
  • All slider controls have a gain range of +/- 30 dB.

Buttons

Clicking on the command buttons give the following results:

  • Manage gives a dropdown menu enabling you to manage presets for the tool and to see some detail about the tool. For details see Manage presets
