Frequently Asked Questions about Audio Cutter
Does trimming degrade audio quality?
No. The segment is extracted while preserving acoustic data and recreating valid container headers cleanly.
How can I achieve millisecond accuracy?
Use the nudge buttons (+0.1s, -0.1s) or type decimal seconds directly into the start and end timestamp fields.
Can I export in a different format?
Yes. You can preserve the original format or export directly to MP3, WAV, M4A, OGG, or FLAC.
Is it secure for confidential audio files?
Absolutely. Zero bytes are uploaded to remote servers. Everything executes inside your local browser sandbox.
