AudioPrism launches on KVR Marketplace: offline GPU stem separation, MIDI export and the KeyPrism piano trainer

AudioPrism 2.0 for Windows is now on the KVR Marketplace: a stem separation and MIDI export app with a built-in piano teacher.

AudioPrism splits any song you own into vocals, drums, bass, guitar, piano and other stems using Demucs, running entirely offline on your own NVIDIA GPU. Drop in a local file or paste a link and it pulls a fresh WAV straight into the separator, with no lossy MP3 step in between. Split stems can be exported as individual MIDI clips to drag straight into your DAW, and a WAV/MP3 converter is built in.

Included in the same purchase is KeyPrism, which turns any song into a falling-notes piano lesson: note names and fingering, 40–100% playback speed, A/B looping, hands-separate practice, per-stem mix faders, keyboard sizes from 25 to 88 keys, and a scored Game mode with combos and rankings. Every transcription carries a PLAYABLE % rating, so you know how reliable it is before you practice it.

Price: $79.99 – AudioPrism is available for Windows 10/11 (64-bit) for $59.99 until October 31. An NVIDIA CUDA/RTX GPU is recommended for the fastest splits.
