The first release: LDAC at its highest quality with one tap, on Samsung and RedMagic phones. The APK is attached to the release.

  • One tap, from a Quick Settings tile or the app, on the headphones Android is playing to.
  • Samsung: a detour via AAC makes the phone reopen the stream, and LDAC ends at 44.1 kHz, 24-bit, top quality (909 kbps), checked against the encoder itself.
  • RedMagic: one LDAC change to 48 kHz, 24-bit, top quality (990 kbps), only while playback is paused, as a change during playback silences the audio chip.
  • Detects the phone's encoder, software or hardware, and the mixer's rate, once per firmware build. This needs the DUMP permission, granted over adb; without it, LDAC Lock changes nothing during playback.
  • A screen with the headphones, the current codec and whether it is locked, that follows the headphones and Bluetooth as they change. Light or dark as the phone is, or as set under Appearance.
  • A tile that shows the result: as its second line on Samsung, and as its name on RedMagic, whose round tiles hide that line. Greyed out while Bluetooth is off.
  • Small and quiet: 73 KB, no libraries, no internet permission, nothing running in the background, and a start in about 140 ms.
