What this tool actually does
A professional remaster is done by an audio engineer, listening and adjusting every part of the recording with judgment. This tool doesn't replace that: it applies volume normalization (so there are no parts too quiet or too loud) and an automatic EQ tuned for the most common cases, like bringing out a voice in a recording or boosting bass in music.
For most home recordings, interviews or voice notes, this automatic adjustment noticeably improves the result without needing any audio editing knowledge.
