■ How the sound is built

1. Sound settings are a console: a signal flow diagram and meters at the head, seven tabs below, Simple for switches or Pro for detail, recommended defaults one tap away.

2. Eleven DSP stages, written by us: De-clip → MA Tone → Tube → Vinyl → Tape → 10-band EQ → Space Reverb → Crossfeed → Voice boost → Studio Clear → Limiter.

3. The EQ follows the RBJ Audio EQ Cookbook, five bands or ten; PEQ-10 sets each band's gain. Volume leveling follows ITU-R BS.1770-4, with album mode. Upscaling adds harmonics above the lossy-codec cutoff, derived from the signal itself.

4. Space comes from Schroeder-Moorer reverb, virtual surround 360° and crossfeed, with eight space presets from studio to cathedral at real reverberation times. Analog color is tube, vinyl and tape.

5. The Output analyzer rates source against processed audio for headroom, clipping, dynamics, tone and stereo width; the Sound effects on switch returns the original. Output path shows both formats and, on Bluetooth, the codec in use and the highest your device supports, with recommended settings applied in one tap.

6. For the expert: true peak (dBTP), gain reduction, stereo width and latency on the console, a -0.3 dBTP limiter ceiling (-1.0 on Bluetooth), automatic headroom, TPDF dither and per-track sound settings.


■ Screen and widgets

In 50 disc modes the album art is the jog wheel, twelve steps to a turn; video gets the same wheel as a translucent ring. The seek step is 5, 10, 20, 30 or 60 seconds, shared by notifications, headsets and widgets. Light and dark themes, six accent colors: terracotta, emerald, sky, rose, violet and amber.


■ 27-band analysis, 100 spectrum meters

LED matrix, Retro VU, Aurora Curtain and more.


■ Library and playback

Today's picks learns from your history, the time of day and the loudness and tone of your files, chooses the next track and says why. Browse by track, album, artist, genre, composer, folder or quality. Narrow to 16-bit or 24-bit; the filter stays until you clear it. Filter MP3, FLAC, WAV, APE, M4A music and MP4, MKV video by format. Lyrics inside the file play in time (synced LRC); they are read from your device and never looked up online. Music and video play from your device; podcasts stream from public RSS, with download ahead, alerts, speed and OPML. Crossfade runs 1 to 20 seconds, 12 by default. Voice commands play a song by name or set a sleep timer. Playback continues in the background and deleted files wait in the trash.


■ How it is paid for

The first 5 launches or 60 minutes are free, no ads - tap "Run free this time". After that, one ad of about 30 to 60 seconds watched to the end opens everything for 24 hours; stopping early grants nothing. To keep it, buy lifetime once. Google Play handles payment and refunds.


■ Our promise

No account to create. We send no listening history or playback patterns to any server; what Google's ad SDK sends during an ad is in the privacy policy. No ads pop up while you use the app.
