What problem does it solve?
HeartMuLa removes the hassle of building and configuring an open-source, local music generation pipeline by providing end-to-end steps to set up HeartMuLa and run song generation from text.
Core Features & Use Cases
- Song generation from lyrics + tags: Produces complete songs conditioned on multilingual lyrics and comma-separated tags.
- End-to-end open-source stack: Works with HeartMuLa (generation), HeartCodec (audio reconstruction), HeartTranscriptor (Whisper-based transcription), and HeartCLAP (audio-text alignment).
- Local/offline workflow: Enables on-device music creation comparable to commercial “Suno-like” experiences without SaaS lock-in.
- Practical hardware scaling: Supports single-GPU and multi-GPU configurations, with lazy loading to reduce VRAM pressure.
Quick Start
Run heartmula by generating from your lyrics and tags using the HeartMuLa checkout and checkpoints (set model_path to your downloaded HeartMuLa ckpt files, point lyrics/tags to your text files, and save the result mp3).
