Player + library

Your music, not another feed.

Built for people who still keep albums, files, and carefully chosen libraries on their Mac. Import FLAC, ALAC, DSD, APE, and other local formats, or sync with Apple Music’s local library.

  • Local files
  • FLAC / ALAC / DSD / APE
  • Apple Music library sync

Add the approved player/library screenshot when the real current asset is available.

Output path

A clean path from file to DAC.

When the playback chain matters, Fidelia keeps the output path predictable. Bit-perfect/exclusive playback and DAC rate following help the Mac behave like a serious source again.

  • Bit-perfect / exclusive
  • DAC rate following
  • Predictable signal path

Use a current output/settings screenshot with bit-perfect or exclusive state visible.

Built-in DSP

Headphones, sample-rate conversion, and dither — built in.

HeadSpace, SRC, and dither live close to the listening session, where they are useful. Shape headphone playback, sample-rate conversion, and final output without opening a full DAW.

  • HeadSpace
  • SRC
  • Psychoacoustic dither

Use current HeadSpace, SRC, or dither UI only.

AU chain

A listening app with a real AU chain.

Fidelia hosts three Audio Unit effects in the playback path, making it useful for checking masters, auditioning playback processing, or monitoring through a familiar chain without opening a DAW.

  • Three AU slots
  • Monitoring / preview
  • Remote control

Use real AU plugins in the chain; optional Remote screenshot can sit beside it when available.
