StemDesk is desktop audio software that separates audio into stems, builds mixes with VST3 processing, and can deliver editable DAW sessions. Its full-mix workflow measures stems and applies per-stem processing, gain staging, panning, sidechain ducking, vocal rides, and mastering. The local AI panel offers mix critique, spectral masking analysis, a session-aware coach, and vocal transcription; optional music generation requires a separate ACE-Step installation. The maker says audio is never uploaded, and that audio, projects, personal data, and telemetry are not transmitted at runtime. Mixing, separation, and plugins work offline, while downloads and an optional one-time AI model fetch need internet. The suite contains 17 plugins, with formats varying by operating system, and lists validated DAW support including Pro Tools, REAPER, Cubase, and Ableton Live. The free plan includes stem separation and three plugins. Pro costs 99.15 USD per once; Studio costs 179.25 USD per once and adds Auto-Mix and more session export options. Listed downloads include Windows 10/11, macOS 13+ on Apple Silicon (beta), and Linux x86_64 (beta).
