Real-time playback format detection
Designed to identify the active playback format as listening changes.
Real-time playback format detection for macOS audio.
Trace what’s actually playing.
Audex Trace detects the active playback format and keeps your Mac’s output in sync — automatically.
macOS 26 ready Beta in development
The gap
Music changes. macOS output often does not.
Albums and tracks can move between 44.1, 48, 96, and 192 kHz while the selected output format stays fixed.
Manual switching in Audio MIDI Setup interrupts listening, and metadata-based guessing can be late or wrong.
Solution
Built for precise, quiet automation.
Automatic output sample rate switching
Keeps the Mac’s selected output rate aligned with what is actually playing.
Menu bar visibility
See the current format at a glance without opening a full control panel.
Works beyond a single player
Initial beta work targets Apple Music and Spotify, with broader app coverage under test.
Safe beta behavior
Avoids unnecessary switching when the detected playback format is uncertain.
Local-only processing
Playback format tracing is handled on the Mac, without cloud processing.
Apps
Beta support is being mapped carefully.
