Quick Tips to Increase Volume in Audacity

🎉 To increase volume in Audacity without losing quality, use the Normalize effect. Open Audacity and upload the audio file; select the track and go to "Effect" > "Volume and Compression" > "Normalize…" to open the box; then, set the values, preview the song, and download it.

Boosting audio volume is essential to ensure clear audibility, particularly in situations like presentations or listening to podcasts or older songs containing almost-inaudible low-volume sections. Constantly adjusting the volume on the audio player can be highly irritating and may lead to extreme loudness levels that can damage hearing.

Luckily, there are solutions to this problem in Audacity, an open-source audio editing software and MP3 volume booster available for free. Four different methods are listed in the article to give a clue on increasing audio volume in Audacity without distortion.

Methods🔊 Effect📢 Difficulty📶
Amplify the Sound Amplify all selected tracks by the same amount. Easy
Normalize the Audio Amplify all selected tracks to the same level. Easy
Use the Envelope Tool Control the volume changers smoothly over time. Difficult
Apply the Compressor Boost quiet voice without clipping. Easy

1. Amplify the Sound in Audacity

In Audacity, the Amplify effect boosts audio volume while maintaining relative track levels. It adjusts each track uniformly based on the loudest one, ensuring clarity without altering the balance between tracks. However, it may distort if the starting amplification volume is too high.

Step 1. Launch Audacity and import your audio file.

  • Go to "File" > "Import" > "Audio" to choose the local file.
  • Audacity supports WAV, AIFF, MP3, OGG, FLAC, and MP2. But if it is an advanced audio coding file like M4A, you'll need to install an FFmpeg library.

import your audio file

Step 2. Select the target track.

Select a part of the audio track or left-click the mouse twice to select the whole song. Or go up to "Select" > "All."

Select the target track

Step 3. Use the Amplify effect.

Move to "Effect" > "Volume and Compression" > "Amplify…" to open the Amplify window. Here you'll see:

Use the Amplify effect

  • Amplification: Enter a value to amplify the sound. Positive values increase volume, while negative values decrease it. Start with a small value.
  • New Peak Amplitude: The highest audio level after applying changes, helping prevent distortion.
  • Allow clipping: When unchecked, entering an amplification value causing a New Peak Amplitude over 0 dB disables the OK button, preventing excessive amplification. When checked (default), you can amplify freely, risking distortion.

Step 4. Preview and download.

Click "Preview" to listen to it, and tap "Apply" to start the process. Export it from "File" > "Export" > "Export as…"

Preview and download

2. Normalize the Audio to Make it Louder in Audacity

The Normalize effect in Audacity serves to adjust peak amplitudes of tracks or selections, ensuring consistency across multiple tracks and balancing stereo channels. It also removes any DC offset present in the tracks. Unlike independent normalization, which maximizes volume per track or channel, Normalize harmonizes peak amplitudes and channel balance across selections and tracks.

Step 1. Open Audacity and load your recordings.

For those who have already saved their audio file as a project in Audacity, try "File" > "Open…" or "File" > "Recent Files" to open it.

 Open Audacity and load your recordings

Step 2. Choose the audio track and apply the Normalize effect.

Go to "Effect" > "Volume and Compression" > "Normalize…" to open the box.

find the Normalize effect

  • Remove DC offset: It centers the waveform at the 0.0 amplitude level to prevent clicks and distortion and maximize available headroom for normalization.
  • Normalize Maximum Amplitude to: Set the maximum level for the processed selection. The default is -1 dB, providing headroom for effects and distortion-free playback. Entering positive values is disabled.
  • Normalize stereo channels independently: Unchecked (default), Normalize preserves stereo track balance. Checked, it adjusts left and right channels separately, suitable for correcting unbalanced stereo recordings after removing clicks.

apply the Normalize effect

Step 2. Preview and download.

Click "Preview" to play the song, and click "Apply" if you like the result. Export the audio file as needed.

3. Use the Envelope Tool to Increase the Volume

The Envelope Tool adjusts volume changes smoothly using control points placed in the track. Each point, with four handles, lets you modify volume levels. Dragging handles prevent distortion beyond the original volume envelope, while inner handles amplify quiet audio beyond the track's envelope.

Step 1. Start Audacity and open the audio track.

If you already have a project in Audacity, try "File" > "Recent Files" to open it.

Start Audacity and open the audio track

Step 2. Choose the whole audio or part of it.

Step 3. Click the Envelop Tool from the tools bar.

Scroll the mouse and press the Ctrl button to magnify the track, and then click the mouse button on a track to add a new control point. To remove it, drag it outside the track.

The sound will transition smoothly between each point you set, so only add what you need. Click on the top or bottom of a track to add a new point. If your track is stereo, both channels will follow the same changes.

Click the Envelop Tool from the tools bar

Step 4. Edit the control points.

Click the control point and drag it while pressing the left mouse. Pulling one control point past another is disabled. You can use it to specify changes in volume and toggle a gain slider to adjust volume without altering the waveform.

Edit the control points

Step 5. Listen and export.

Once you are satisfied with the final work, export the format you want.

4. Apply the Compressor to Enhance the Volume of a Section in Audacity

In scenarios like presentation recordings where the presenter's mic captures questions from the audience at a lower volume, you may only want to adjust specific parts of the audio volume. This is where the built-in compressor becomes valuable. It reduces the dynamic range of the audio without causing clipping, effectively managing varying volume levels within the recording.

Step 1. Upload your audio file to Audacity and select the target part.

For files without standard headers like RAW or VOX ADPCM or those with non-standard headers, use "File" > "Import" > "Raw Data" to import them in Audacity.


Step 2. Use the Compressor.

Access "Effect" > "Volume and Compression" > "Compressor…" and you'll see the graph.

find compressor

  • Threshold: Compression level value.
  • Noise Floor: Control audio gain below background levels to prevent over-amplification.
  • Ratio: Reduce audio beyond a threshold. Higher Ratios compress louder parts more.
  • Attack Time: Decide how fast it reacts to volume surpassing the threshold. Short attack times react to loud sounds.
  • Release Time: Decide how quickly it restores volume after dropping below the threshold. Long release times sacrifice softer sounds after loud ones.
  • Make-up gain for 0 dB after compressing: Post-compression, all selected tracks are amplified to reach a peak level of 0 dB, utilizing the same amplification as the Amplify effect.
  • Compress based on Peaks: Adjust threshold and gain based on peak waveform values for "upwards" compression, amplifying louder sounds less than quieter ones, contrasting with "downward" compression of RMS, which reduces louder sounds while leaving quieter ones unchanged, with no amplification at the original 0 dB level.

Use the Compressor

Step 3. Export.

Apply the options and preview. Select the folder to store the audio, and choose the sample rate, audio options, and export range.

Audacity Increase Volume FAQs

1. How to increase audio volume without losing quality?

For a quick volume boost without altering dynamics:

  • Use normalization to bring up the volume of the entire audio file so that the highest peak volume is just below 0 dBFS. This process does not add distortion or clipping.

For producers aiming for a louder sound in the "loudness war":

  • Consider using multi-band compression, like the t.c.electronic finalizer, to increase the average volume of the audio without necessarily raising the volume of the highest peaks. This method can make the audio sound louder to human perception.

2. How do I increase volume in Audacity without clipping?

To increase volume in Audacity without clipping:

  • Load an audio file in your Audacity.
  • Select the track and move up to "Effect."
  • Choose "Normalize…" and set the peak amplitude to 0 dB.
  • Press "OK" and listen to your recording.

3. Why is my Audacity volume so low?

Your Audacity volume is low:
