What Is an Audio Volume Booster?
An audio volume booster permanently increases the loudness of a digital audio file by applying gain — multiplying the amplitude of every sample. Unlike turning up your speaker volume, boosting the file itself means the louder version plays back at higher levels on any device, in any app, and after any upload.
When to Use a Volume Booster
Quiet voice memos and phone recordings
Podcast episodes recorded at low gain
Old music rips with low mastering levels
Lecture and meeting recordings
Audio extracted from quiet video files
Ringtones and notification sounds
