Add recording or background music files and adjust the volume from 0 to 300% using the slider or a numeric value. To amplify quietly recorded voices or reduce overly loud audio, compare with the original and save as an audio file. 100% is the original volume, and 0% is silence. Lower the volume if clipping occurs.

Tips for adjusting volume

100% is the original volume

Below 100% is quieter, above 100% is louder, and 0% is silence.

Preview volume and saved volume

The player’s speaker control changes listening volume. Specify the value applied to the file in “Volume (%).”

Watch for distortion

Amplification may distort loud sections. If you notice distortion in the preview, lower the configured volume.
