How to Cut Audio Without Losing Quality
Every time you save an MP3, quality drops slightly. Here's how to cut audio and keep every bit of quality intact.
Why Cutting Can Reduce Quality
When you trim an MP3 and save it as MP3 again, the file gets re-encoded. Each MP3 encoding pass removes a tiny bit of audio information. After multiple edits, the quality degradation becomes noticeable. This is called generation loss — the same problem that made VHS copies of copies look terrible.
The Lossless Solution
To cut without any quality loss, export in a lossless format: • WAV — uncompressed, perfect quality, larger file size • FLAC — compressed but lossless, smaller than WAV, perfect quality In cut.audio, load any audio file (even MP3), set your trim points, and export as WAV or FLAC. The exported file preserves the full quality of the original. If you need MP3 for compatibility, cut first in WAV, then convert to MP3 once at the end.
When Quality Loss Doesn't Matter
For many use cases, MP3-to-MP3 trimming is perfectly fine: • Making a ringtone — phone speakers won't reveal the difference • Sharing a clip on social media — platform compression is worse than your edit • Quick voice memo trim — speech isn't demanding on quality • Casual listening — most ears can't tell the difference Only worry about lossless when you're doing professional work or when the file will be edited again later.

Both are lossless — identical quality. FLAC is about 50-60% the size of WAV. Use FLAC if file size matters, WAV if compatibility is more important (some older software doesn't support FLAC).
Yes. Load FLAC, trim, export as FLAC. Lossless in, lossless out — zero quality loss.
