Engineer Guy AI Master Track review
A focused web mastering service with reference matching and platform-specific loudness targets.
Reviewed by iTechGuides Editors · Editorial team · Updated Sep 2026
Engineer Guy AI Master Track is a browser-based AI mastering service for independent producers, beatmakers, songwriters, and other music creators. It analyzes an uploaded WAV or MP3 mix and applies a mastering chain customized to that track. The service is designed for demos, independent releases, social content, and other streaming-oriented projects. Its cloud deployment and web platform suit solo creators and small teams that want a focused mastering workflow rather than a broader production environment.
The standout feature is reference-track matching. Users can provide a reference to guide tonal character and loudness profile, while the service also offers platform-specific loudness targets for Spotify, Apple Music, and YouTube. Technical controls and checks include a true-peak ceiling set to -1 dBTP, integrated LUFS measurements, true-peak readings, dynamic-range measurements, spectral analysis, mastering-grade limiting, and EQ. Together, these features give creators both automated processing and measurable output characteristics before exporting a WAV master.
Engineer Guy AI Master Track uses a freemium pricing model, and a 14-day refund period is listed. The workflow is intentionally narrow: upload a mix, apply the AI mastering chain, review the measurements and analysis, then export the master. Email support is available, and no card is required for the trial. Choose it if your priority is reference-guided, platform-aware mastering in a browser. Choose another option if you need desktop software, extensive integrations, or a wider set of music-production features beyond mastering.
