Audex Trace

Audex Trace is a focused macOS companion for Apple Music that reveals technical playback details typically hidden by the Music app. It displays the active codec, bit depth, sample rate, and output match status in a compact player, menu bar, or notch view. The app includes a Playing Next queue with estimated Lossless/Hi-Res quality and skip risk warnings for upcoming tracks. The Pro version adds experimental Auto Sample Rate Match to automatically update compatible output devices when Apple Music switches sample rates. Designed for macOS 15+, it runs locally with no audio recording or cloud library access. A free download includes Compatibility Check and basic features; Pro is a one-time purchase.
