- Delivers a clear mastering verdict: Excellent, Good, Mediocre, or Poor
Built for audiophiles:
- Streams directly from your WebDAV server — no need to copy files to your device

- Analyze full albums at once with per-track breakdown
- Visualize waveforms, frequency spectrum, and stereo vectorscope

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
DR is now measured over the entire track on every channel, matching foobar2000 and the TT DR Meter; values for some albums may change. Improved DSD (DSF) analysis with full stereo. WAV, MP3, AAC, M4A and AIFF files on WebDAV servers now analyze correctly. Faster folder analysis.
