About this app

StemDeck is a powerful, open-source audio separation application that runs entirely on your local hardware. Designed as a fully private, free alternative to cloud-based tools like Moises and LALAL.AI, it lets you extract individual instruments from your favorite tracks without subscriptions, quotas, or cloud uploads.

Core Features:



     
  • 6-Stem Machine Learning Splitter: Powered by Meta AI's advanced Demucs neural network to isolate vocals, drums, bass, guitar, piano, and backing elements cleanly.

  •  
  • DAW-Style Multitrack Mixer: Fine-tune your extracted tracks natively with volume faders, individual solo/mute configurations, live VU meters, and responsive waveform zooming.

  •  
  • Smart Audio Analysis: Automatically calculates song BPM, key detection, scale confidence metrics, and integrated peak loudness levels.

  •  
  • Frictionless Ingestion: Drag and drop local MP3, WAV, or FLAC files directly into the client, or paste a video link for rapid processing.


Note: On its very first startup, StemDeck's built-in installer will automatically download its local runtime environment and AI model weights (~670 MB total). Subsequent boots open instantly.
