A cult Mac music player returns for the no-subscription era.
Fidelia is a rebuilt Mac music player from Audiofile Engineering for listeners and professionals who still own music, care about the playback chain, and want a private listening room instead of another algorithmic feed.
Owned music still deserves serious software.
Fidelia first appeared in the Mac audiophile-player era. In 2026, Audiofile rebuilt it for current macOS around a timely idea: owned music still deserves serious software.
The new Fidelia pairs a Swift app and C++ audio engine with bit-perfect/exclusive playback, built-in DSP, Audio Unit hosting, Fidelia Remote, no subscription, and no data collected.
Why Fidelia matters now.
Owned-library focus — local music libraries and real files, not streaming-first behavior.
Mac-native rebuild — current macOS app, not a cosmetic shell around old assumptions.
Playback-chain control — bit-perfect/exclusive mode and DAC rate following for predictable output.
Built-in Audiofile DSP — HeadSpace, SRC, and dither in the listening path.
Professional workflow edge — three AU plugin slots and Fidelia Remote make it useful for review, mix/master preview, and reference playback.
