Audio Split - Cut an Audio File into Multiple Parts Online — Divide any audio file (MP3, WAV, FLAC, OGG, M4A and more) into several parts. Split at your own time points (in seconds or HH:MM:SS), or split the whole track into N equal parts. Download each part as MP3, WAV, FLAC, OGG, AIFF, ALAC or WavPack. Everything is processed locally in your browser, with files never uploaded to a server.
Supported input: MP3, WAV, FLAC, OGG, Opus, M4A, AAC, WMA, AIFF and other common audio formats. Files are never uploaded to a server.
First use loads an ~30MB audio processing engine into the current browser. It is cached and reused afterwards, so please be patient.

Split at time points: Enter time points where the file should be cut, separated by commas. Each point is the start of a new part. Accepted formats: seconds (e.g. 30, 90) or HH:MM:SS (e.g. 00:00:30, 00:01:30). Example "30, 90, 00:02:00" makes 4 parts.
Split into N equal parts: The file is divided into N parts of equal length (the last part may be slightly shorter).
Units: time points accept sec (e.g. 30) or HH:MM:SS (e.g. 00:00:30). Points must be greater than 0 and less than the total duration of the file, which is shown in the blue box above after you select the file.
Does splitting an audio file lose quality? Splitting here decodes the audio and re-encodes each part — it is not a frame-level lossless slice. Output to a lossless format (WAV, FLAC, AIFF, ALAC, WavPack) and no further lossy compression is added. Splitting an MP3 to MP3, however, adds one more lossy generation: the source's compression artefacts are kept and a small new layer of them is added, so if the parts will be processed further, prefer a lossless output. Lossless formats in general are explained on the Audio to WAV / FLAC page.
