Recording came out too quiet? This mp3 volume booster raises the level up to +18 dB (or lowers it, down to −12) with a single slider — processed on your device. For files with occasional loud peaks, the audio normalizer is the smarter choice; the booster is the right tool when the whole file is simply too quiet.
