Tunr is a desktop audio mastering app for macOS and Windows that analyzes tracks and creates genre-aware masters locally. Mastering works without an internet connection. Auto mode applies a mastering chain, while Reference mode matches a selected track’s tone, dynamics, and loudness; that mode accepts WAV, FLAC, and MP3. The A/B Mixer supports crossfades, null and blind tests, loudness matching, and stereo, mono, mid, or side listening. Batch mode processes queued tracks in sequence using the same settings and saves each as it finishes. Without a licence key, the free plan renders three masters per machine; mixer comparison and analysis do not count against that limit. A free licence key gives unlimited masters on two machines. Tunr is standalone rather than a DAW plugin, and supports macOS 11 or later on Apple Silicon and Intel, plus 64-bit Windows 10 or later. The maker says audio files are not uploaded and the app has no usage telemetry or third-party trackers.
Who it is for
