What to watch out for
| WAV cuts are exact | There are no frames to align to, so a cut lands on the sample you asked for. This is the format to cut in when precision matters. |
|---|---|
| The files are large | A minute of 44.1 kHz stereo WAV is about 10 MB regardless of content, because nothing is compressed. That is the trade for the precision. |
| Convert last | Cut in WAV, then convert to MP3 or AAC once at the end. Every extra lossy encode costs quality that cannot be recovered. |
FAQ
How is this different from MP3 cutting?
WAV is uncompressed PCM, so cuts are sample-accurate. MP3 cuts snap to frame boundaries (~26 ms). WAV is the right choice when you need DAW-grade precision.
Will the file size shrink?
Yes — proportional to the trimmed duration. WAV files are large (~10 MB per minute of stereo CD-quality audio), so cutting saves real disk space.
Does this run in my browser?
Yes — the tool uses FFmpeg compiled to WebAssembly. Your file never uploads to a server, never leaves your device, and there is no signup or watermark.
