Audacity is a professional digital audio editor commonly used on Windows and Mac. It provides a lot of features for processing audio files, such as loudness normalization, noise reduction, reversing, changing playback speed, etc. Its Normalize effect can help you make a single WAV track, multiple wav tracks, or a selection of them at the same peak amplitude, remove DC offset, and equalize the balance of left and right channels of stereo tracks. Let’s see how to make your WAV files at the same sound level in Audacity:

Step 1: Run Audacity.

Step 2: Go to "File" > "Open" and select WAV files to add them to the program.

Step 3: Press "Ctrl + A" to select all tracks. Click "Effect" and choose "Normalize" from the menu.

Step 4: Check the "Normalize peak amplitude to" option and set a wanted level.
By default, the peak amplitude setting is "-1dB". The volume of the entire selection will increase until the loudest part of the audio (peak) reaches the target of -1dB.

Step 5: Hit "Preview" to check what it sounds like. Once it is ok, click "Apply".

Step 6: Go to "File" > "Export" > "Export as WAV". Select an output path and click "Save".

Note: Increasing the audio volume will also make background noises in the track louder.
