This page lets you change the volume of an audio file — boost it or turn it down — and save the result.
Supported file formats are MP3 and AAC (m4a/mp4).
This tool comes in handy when:
You recorded an instrument with a microphone, but the recording turned out too quiet
Your smartphone's maximum volume is too low, and your favorite music is hard to hear even at full blast
Some songs in your player are much louder or quieter than the rest, and you want to stop adjusting the volume every time
