Audio Trimmer trims, cuts, fades, normalizes, resamples and changes the speed of MP3, WAV, M4A, FLAC and OGG audio on a waveform, and takes the audio track out of MP4, MOV and WebM video. It exports WAV (16-bit or 32-bit float) or MP3 and runs entirely in your browser, with nothing uploaded.
Drag across the waveform to select, then trim, cut, fade or level the selection.
Speed resamples, so the pitch moves with it. 16000 Hz mono is what the speech tools here expect. A Voice Studio reference clip must be 3 to 30 seconds; the badge beside the length turns green when the selection fits, and opens Voice Studio in a new tab.
Export saves the selection, or the whole file when nothing is selected or Whole file is chosen.
