Tunr review
A free desktop mastering tool with reference matching and batch processing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Tunr is a standalone desktop audio mastering app for music producers, artists, and independent audio creators. It analyzes tracks locally and applies genre-aware processing for EQ, dynamics, warmth, stereo width, and loudness. Users can work with WAV, FLAC, or MP3 input, then export 16-bit or 24-bit masters. Its offline operation suits creators who want to process unreleased tracks locally rather than upload them.
The Free plan costs nothing and includes all four modes, 16-bit and 24-bit output, and no credit card requirement. The published plan allows three masters before a free licence key is required; after obtaining the key, it supports unlimited masters. That structure keeps the product accessible for ongoing personal or small-scale work while adding a small activation step after initial use. Tunr is aimed at solo users and small teams rather than organizations looking for multiple deployment options or a broader service platform.
Tunr’s strongest area is its focused mastering workflow. Reference-track matching helps users work toward a chosen sonic target, while the A/B mixer provides loudness matching and null testing for comparisons. True-LUFS loudness processing and folder batch mastering add practical control for repeated exports. The trade-off is its narrow desktop scope: verified platform coverage is limited to Windows and macOS, and support is provided through email. Choose Tunr if free offline processing, batch work, and reference comparison are central to your workflow. Consider another option if you need a browser-based tool, mobile support, or a wider support ecosystem.
