Audio Trimmer

Cut a clip out of any audio or video file, clean it up, and export WAV or MP3. Decoding, editing and encoding all happen on this device — the file never leaves your browser.

Drop an audio or video file

MP3, WAV, M4A, FLAC, OGG and Opus, plus MP4, MOV and WebM — dropping a video pulls out its audio track.

Edit

Trim keeps only the selection. Delete cuts it out and joins what is left. Ctrl+Z and Ctrl+Shift+Z step through the last 12 edits.

Fade length 1.00 s

Fades are applied at the start and the end of the current selection. Logarithmic ramps in decibels, which sounds more even.

Level

Peak target

Manual gain 0.0 dB

Both act on the selection. Use “Select all” first to level the whole file. Peaks are clamped, never wrapped.

Silence threshold -45 dB

Load a file to scan its head and tail.

Resample to

16000 Hz mono is what the speech tools on this site expect, and it makes the smallest useful file.

Speed 1.00×

This resamples the audio, so the pitch moves with the speed — like playing a record faster. It is not pitch-corrected.

Format

WAV 16-bit is lossless and works everywhere, including Voice Studio.
