MP3 and WAV files. If your track is in another format, convert it to one of these before uploading.
Most tracks finish in under two minutes, depending on the song's length and how busy the server is at the time.
Stemline101 uses an AI audio separation model trained to recognize the different instruments and voices layered in a mix. It analyzes the track and pulls each part — vocals, drums, bass, guitar, synth, and other instrumentation — into its own clean audio file, so you can work with them individually instead of the full mix.
Stemline101 is free to use, with ads and up to 5 song splits per month. If you want more, Premium removes ads and unlocks unlimited splits for $5.99/month or $39.99/year.
