Stem Splitter

A stem is an isolated component, group, or part of a song. For example, a typical pop song could be split into stems for vocals, piano, drums, bass, and other instruments. Each stem is typically a separate audio file that can be played or remixed separately, giving producers granular control over each part of the music.

If you recorded each track of a song separately, then you already have separate stems and do not need a stem splitter. However, if you only have a full mix of a song and you want granular control over each part, then you need to split the stems. Splitting a song into stems allows you to do the following cool things:

• Practice: Mute one part and play along, or play only one part to help you transcribe it.
• Remix: Take just one isolated part like the vocals and remix it with other parts of your own creation. You can raise the volume of the vocals to hear the lyrics better, or you can crank up the bass if you want to make your neighbors mad.
• Perform: Use the backing track without vocals and sing to it during a live performance.

Our tool performs audio source separation using machine learning techniques. All you need to do is upload an audio file, and our tool will automatically split the various parts into stems. As soon as the process completes, you can download a zip file containing multiple audio files. Each audio file represents one stem or isolated part of the song. Then you can import each part (vocals, piano, drums, bass, etc.) into your favorite DAW and start mixing.

You can upload MP3, WAV, FLAC, M4A, OGG, and other common audio formats. Each output stem is provided as a high-quality audio file inside a downloadable ZIP archive.

You can upload an audio file up to 100 MB in size. If your file is too large (often the case with wav files), you can use an online converter such as cloudconvert to first convert to mp3 for a much smaller file size. Free users receive the first 30 seconds converted at no cost. Upgrade to a Flex or Pro plan to convert up to 30 minutes per file.
