MP3, WAV, M4A/AAC, FLAC, Ogg, Opus and WebM — whatever your browser can play. Audio is processed on your device and never uploaded.
Any audio format your browser can play.
Fade in and fade out up to 30 seconds, with the shape you prefer.
Hear the start and end with the fades applied, then save as MP3 or WAV.
Logarithmic and equal-power fades sound natural to the ear for music; linear can sound abrupt at the end of a fade-out; S-curve is smooth at both ends; exponential lingers quiet longer.
A few seconds for the end of a song, 0.5–2 s for speech, and 10–50 ms just to remove a click at a cut.
Edit
Cut an MP3, WAV or other audio file to the part you want: drag across the waveform, fine-tune the times, and save as MP3 or WAV — in your browser.
Edit
Join several audio files into one, in the order you choose, with optional gaps or crossfades — mixed formats and sample rates are handled for you.
Edit
Split an audio file into parts at points you click, into equal parts, every N seconds or at silences, and download each part or all of them as a ZIP.
Edit
Make audio louder or quieter by decibels, normalise to a peak level, or to a loudness target (LUFS) for Spotify, YouTube, Apple Music or podcasts.
Edit
Speed up or slow down audio without changing the pitch — or tape-style, where pitch follows speed — from 0.25× to 4×.
Edit
Shift the pitch of a song or recording up or down by semitones and cents while keeping its length — to change key or practise along.
