Audio tasks tend to be simpler in scope than video — converting between formats for compatibility, or trimming a clip down to just the section you actually need — but still benefit from not requiring a dedicated audio editor for something this straightforward.
Format choice matters more for audio than people often realize. MP3 is universally compatible but lossy (some audio data is discarded to reduce file size). WAV is uncompressed and higher quality, but produces much larger files. For most everyday sharing and listening, MP3 at a reasonable bitrate is genuinely indistinguishable from lossless audio to most listeners — the difference matters more for professional audio work than casual use.
Trimming audio precisely — cutting exactly where you want, not approximately — depends on being able to preview the exact cut point before committing to it, rather than guessing based on a timestamp alone. This matters especially for things like trimming a voice memo or removing dead air from the start of a recording, where a fraction of a second in either direction is noticeable.
