Demucs.net is an independent, unofficial web interface for running the open-source Demucs music source separation model. A visitor can upload an audio file, choose a model and stem layout, and separate a song into vocals and instrumental tracks without installing Python, PyTorch or CUDA. The site supports two-stem vocal separation and multi-stem outputs for drums, bass and other sounds. It offers in-browser playback and individual stem downloads. MP3, WAV, FLAC, M4A and OGG are accepted as uploads. A signed-in account is required to start a separation. Free monthly credits are available after sign-in, and paid plans or credit packs provide more capacity. Demucs.net is a third-party hosted runtime and is not affiliated with, endorsed by or sponsored by Meta or the Demucs authors. Users are responsible for rights to their uploaded audio and resulting stems.
