Audacity is a free, open-source audio editing tool compatible with multiple operating systems, including Windows, Mac, and Linux. This free utility is packed with a wide variety of features and can be used for recording audio, applying sound effects, enhancing sound quality, etc. Also, you can let Audacity increase volume when your music files or audio recordings are not loud enough.
Next, let’s walk through the step-by-step process of how to increase volume in Audacity easily.
Audacity provides multiple options to adjust the audio volume and Amplify and Normalize are two of the most essential effects built into it. They both can help increase volume but behave differently if used on multiple tracks or channels.
Amplify can change the level of one or more tracks or channels by the same amount, eventually maintaining the balance between them. Normalize Effect is very useful to correct DC offset (which is not supported by Amplify) and adjust multiple audio tracks or channels to the same peak level.
First, let’s learn the quickest way to change volume in Audacity. Simply move the slider (on the left of the Track Control Panel) towards the “+” sign to increase, and move it to the “-” sign to decrease. Note that this isn’t a permanent adjustment. You can restore it to its original value anytime.
Next, let’s learn how Audacity increase volume without distortion by using Amplify effect.
Step 1. Click File on the Audacity menu bar to import the audio file you want to boost up the volume.
Step 2. Hit the Selection Tool on the tools toolbar. Then left-click to select the part of the audio you want to adjust. To apply the effect to the entire file, click Select > All or simply press Ctrl + A on your keyboard.
Step 3. Then go to Effect > Volume and Compression > Amplify.
Step 4. In the Amplify dialog, type a value in the Amplification (dB) text box for the amount of amplification you would like to apply. Alternatively, you can drag the slider to increase or decrease the volume of your audio files. The New Peak Amplitude (dB) is to set the target volume you want to reach.
Note: Positive values make the sound louder, and negative values make it quieter.
To use the Normalize effect, take the following steps:
Step 1. Load the audio files from File > Import. Then navigate to Effect > Volume and Compression > Normalize.
Step 2. Set Normalize peak amplitude to the level you want. Hit the Preview button to check the effects, and click to Apply the change.
Step 3. At last, hit File to Export the edited audio file as MP3, WAV, OGG, etc.
Note that applying Normalize to increase the volume of a collection of recorded audio files can also make the background noise in your track louder.
