Cryo Mix vs StemDesk

Cryo Mix is a browser-based AI mastering service for finished stereo mixes. Users upload a mix, optionally add a reference track, then review and download the mastered version. Plain-language directions to Nova, presets, and advanced settings provide ways to guide the process; a reference can help target tone, loudness, and dynamics while retaining the mix’s character. Before export, analytics show loudness, true peak, dynamics, and tonal balance. Users can preview the full-length result without a credit card and iterate before downloading; each download uses one credit per project. The service offers WAV export and lists input formats including WAV, MP3, FLAC, AIFF, M4A, AAC, and OGG. Its browser workflow runs on Mac, PC, tablet, and mobile, and Cryo Cloud Storage saves masters, versions, and source mixes for access from any device. Pricing starts at $19/mo, with five tracks per month listed. Cryo Mix says users keep ownership of their music and files and that their audio is not used to train AI models. It is aimed at independent artists, producers, content creators, and small labels.

StemDesk is desktop audio software for separating audio into stems, shaping a mix with VST3 processing, and exporting editable DAW sessions. Its auto-mix workflow measures stems and applies per-stem processing, gain staging, panning, sidechain ducking, vocal rides, and mastering. A 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. Mixing, separation, and plugins work offline, though downloads and the optional one-time AI model fetch require internet access. The maker says audio, projects, personal data, and telemetry are not transmitted at runtime. The suite includes 17 plugins, with plugin formats differing by operating system, and lists support for several DAWs, including Pro Tools, REAPER, Cubase, and Ableton Live. Free includes stem separation and three plugins. Pro is $99.15, paid once; Studio is $179.25, paid once and adds one-click Auto-Mix, session building and exports, and batch album processing. Downloads are listed for Windows, macOS on Apple Silicon (beta), and Linux (beta).
