How do I cut or trim an MP3 online?

Load your file into the GoChronos Audio Cutter, drag the start and end handles on the waveform to the section you want to keep, then export as MP3 or WAV. Everything runs in your browser — no upload.

Can it remove silent gaps automatically?

Yes. Switch to the Remove silence mode and the tool detects silent gaps by loudness threshold and trims them, with adjustable threshold, minimum gap and padding so cuts don't sound abrupt.

Can I split one recording into several files?

Yes. The Split mode divides a recording into equal parts, fixed-length chunks, or automatically at silent gaps, and lets you download the parts individually or all at once as a ZIP.

Do I lose quality when trimming?

No. Trimming and silence removal are sample-accurate edits. Exporting to WAV is lossless; MP3 re-encodes at your chosen bitrate.

Is the Audio Cutter free?

Yes. Free on GoChronos, processed on your device, works offline.
