FUSER vs StemDesk

FUSER is an audio plugin that detects frequency clashes between tracks and reduces them dynamically, helping competing parts occupy space in a mix. Resolve Conflicts processes detected channel conflicts and frequency masking automatically. Phase Analyze identifies a phase rotation intended to reduce cancellation between layered sounds. Users can adjust mid/side, Q, attack, and release controls, and listen to the Delta signal. FUSER supports stereo processing and offline file analysis, with views for loudness, peaks, stereo balance, phase correlation, dynamic range, loudness range, and tonal balance/EQ. It runs on macOS 10.15 or later and Windows 10 or later; the Mac version is native for Apple Silicon. Mac hosts can use 64-bit AU, VST 3, or AAX, while Windows hosts can use 64-bit VST 3 or AAX. The listed price is £59 as a one-time purchase, and the maker offers a fully functional 15-day trial. A 30-day money-back guarantee is also listed, subject to deactivation and a support request within 30 days of purchase.

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).
