BeatStitch: free open-source desktop app auto-mixes songs with beat-matched blends
AIandDesign · x · 2026-10-14
BeatStitch is a new free, fully open-source desktop app (macOS/Windows/Linux) that stitches songs into one continuous mix. It time-stretches tracks with Rubber Band R3 to match tempo without changing key, aligns beat grids so kicks line up, and hands the bass between songs during blends. All processing runs locally; analysis models are optional downloads (macOS 14+ on Apple Silicon, x64 Windows/Linux).
