## What is drobimobile?

Dr. Doctor — Audio Mastering Analyzer
  Know exactly what you're listening to. Dr. Doctor analyzes your music library and reveals the true
  quality of every track.
  What it does:
  - Measures Dynamic Range (DR), Loudness (LUFS), True Peak, and Crest Factor
  - Detects clipping and inter-sample peaks
  - Spots fake lossless files (lossy upconversions disguised as FLAC or WAV)
  - Analyzes stereo imaging, phase issues, and per-band stereo width
  - 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
  - Supports WAV, FLAC, AIFF, ALAC, DSD (DSF/DFF), MP3, AAC, and OGG
  - Analyze full albums at once with per-track breakdown
  - Visualize waveforms, frequency spectrum, and stereo vectorscope
  Stop guessing. Start diagnosing.


## Version history (last 3 releases)

### 5.1 — 2026-04-28

What's New in this Version
  Improved Dynamic Range accuracy — now matches the official DR14 standard
  Heads up if you've used previous versions: DR scores in this release may read 2–4 points lower than before. This is not a regression — it's a
   correction.
  The previous algorithm produced systematically optimistic readings due to three deviations from the Pleasurize Music Foundation DR14
  specification. Dr. Doctor now uses the same formula as the public DR Database (dr.loudness-war.info), the TT DR Meter, and the foobar2000 DR
  plugin. Your numbers will now line up with the values audiophiles and mastering engineers have referenced for over a decade.
