Frequently Asked Questions
What formats are supported?
MP3, WAV, M4A, AAC, and OGG. The output preserves the original format.
Is there any quality loss when trimming?
No. Trimming uses stream copy — the audio data is cut without re-encoding, so there is no quality loss.
Can I trim to millisecond precision?
Yes. The time inputs accept decimal values like 12.5 (12 seconds, 500ms). Stream copy trims to the nearest keyframe for some formats.
