Built-in DSP

HeadSpace, SRC, and dither.

Headphone processing with frequency-dependent crossfeed modeled on real head acoustics, sample-rate conversion, and final-stage dither sit in the listening path. No DAW or outboard processing required to shape the chain.

DSP — HeadSpace, SRC, and dither live close to the listening session, not buried in a DAW.
AU chain

Three Audio Unit slots in the listening path.

Host three AU effects inline. Audition masters through a familiar chain, monitor through the plugins you trust, or check a mix without opening a session. Fidelia Remote controls the chain from the listening position.

Output path

A clean path from file to DAC.

Bit-perfect and exclusive playback. Sample rate follow. The Mac stops behaving like a streaming box and starts behaving like a boutique hi-fi.

Remote control

A companion app. Control transport, library, volume, and even the AU effects from where you actually listen — not at the keyboard.

Reception

“There is nothing that looks or works like Fidelia.”

“What matters most is having an audio player that plays back my signal accurately and without coloration. As someone working in a recording studio, that is extremely important to me. I honestly don’t think there is any comparable tool out there.”

— Raffael Gruber, Austria

“Uso Fidelia hace más de 10 años, y sólo puedo decir que es el mejor reproductor de audio para MacOS. El sonido, poderoso, sedoso y analítico sin sobresaltos.”

— nodata80, Chile

“I’ve been using this player for years, and it has no equivalent.”

— JnCmbn, France
