MP3, WAV, M4A/AAC, FLAC, Ogg, Opus and WebM — whatever your browser can play. Audio is processed on your device and never uploaded.
It's reversed immediately and shown as a waveform.
Play the reversed audio, then save it as MP3 or WAV.
No — reversing only reorders the samples. Save as WAV to keep it exact; MP3 re-encodes.
Sound design (reverse cymbals and reverb swells), checking for backmasking, games and puzzles.
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
Add a fade-in and fade-out to audio with linear, exponential, logarithmic, equal-power or S-curve shapes, and hear the result before saving.
Edit
Speed up or slow down audio without changing the pitch — or tape-style, where pitch follows speed — from 0.25× to 4×.
