What StemSplit is
StemSplit separates songs into vocals, instrumentals, and other stems for karaoke, music production, and related audio work. It offers four-stem separation, as well as a six-stem mode that additionally separates guitar and piano. Users can upload common audio formats such as MP3, WAV, FLAC, M4A, OGG, WEBM, AAC, OPUS, AIFF, AIF, and WMA, up to 100 MB, or submit YouTube and SoundCloud URLs. Batch processing is supported, with MP3, WAV, and FLAC exports. StemSplit says most tracks finish in under a minute and advertises 95%+ separation accuracy.
