What it is

Tunr is a desktop audio mastering app for macOS and Windows. It analyzes tracks and creates genre-aware masters on the user’s computer, with no internet connection needed for mastering. Auto mode applies a mastering chain; Reference mode uses a chosen track to match tone, dynamics, and loudness. That mode accepts WAV, FLAC, and MP3. Its A/B Mixer supports equal-power crossfades, null and blind tests, loudness matching, and listening in stereo, mono, mid, or side. Batch mode processes queued tracks in sequence with shared settings and saves each result as it finishes. Without a licence key, the free plan renders three masters per machine; mixer comparisons and analysis do not count toward that limit. A free licence key provides unlimited masters on two machines. Tunr is standalone, not a DAW plugin. It supports macOS 11 or later on Apple Silicon and Intel, plus 64-bit Windows 10 or later. The maker says files are never uploaded and the app has no usage telemetry or third-party trackers.

  • It requires macOS 11 or later or 64-bit Windows 10 or later.

Who it suits

Tunr suits musicians who want desktop mastering with either an automatic chain or reference-track matching. It is also suited to users who need batch processing or A/B comparison tools.
