Listen before setting cut points. Leave a little room before the first consonant and after the last word or note; cutting exactly at the visible waveform can clip speech or create a click.
Preview the edit in the audio trimmer, then export and listen to the actual file from start to finish. Check whether a format conversion changes volume, channels, or quality. If the clip needs a fade, use a short one that does not erase meaningful sound.
Keep the original recording in case you need to adjust the boundaries.
