Cut the part you need out of a song, a voice memo or a recording. Drag the start and end, play the selection, add a fade if you like, and download. It all runs in your browser, so the file stays on your device.
Your file never leaves your device. Nothing is uploaded.

mp3, m4a, wav, ogg, flac, and the audio from mp4 or mov video. Up to 500MB. Cut on your device, never uploaded.
Processing runs on FFmpeg, compiled to WebAssembly, inside this browser tab. Licences and source
No. The cutter is FFmpeg running inside your browser, so the file is read and cut on your own device and the result is saved straight back to it. Wave never receives the audio or the file name; we only count that a cut happened, with the format and a rough size range.
Not if you keep the original format and leave fades off. The cutter then copies the audio frames as they are, without re-encoding, so the clip sounds exactly like the original. With a fade or a different output format, the clip is re-encoded at 192 kbps (MP3 or M4A) or saved as lossless WAV.
When the audio is copied without re-encoding, the cut lands on the nearest audio frame, which for MP3 is about 26 milliseconds. When it is re-encoded (fades or another format), the cut is exact to the sample. You can type times to a tenth of a second.
Yes. Open an MP4, MOV or WebM file and the cutter works on its soundtrack. Save the clip as MP3, M4A or WAV; the picture is dropped.
Files up to 500MB. The waveform is drawn for recordings up to 30 minutes; longer files get a plain timeline, and cutting works the same. Because everything runs in your browser's memory, very large files can fail on phones.
Yes. Cut a clip of up to 30 seconds, add a short fade in and out, and save it as M4A for iPhone (rename it to .m4r) or MP3 for Android.
