Fidelia — Hi-Res Music Player

Bit-Perfect FLAC & USB DAC

Free

The audiophile player, now on iPhone. Your FLAC and hi-res library, played bit-perfect to your USB DAC. Free 14-day trial — one purchase, no subscription. Fidelia is the audiophile music player Mac listeners have trusted for over a decade — now on iPhone. Bring your own collection — FLAC, ALAC, WAV, AIFF, DSD, MP3, and more — and hear it the way it was mastered. No subscription, no account, no one else's cloud. YOUR LIBRARY, LEFT IN PLACE Point Fidelia at a folder and play. Your files are referenced where they live — never copied, never re-tagged, never uploaded. Fast browse and search by song, artist, and album, built to stay quick in six-figure libraries. Everything plays offline; nothing needs a signal. BUILT FOR YOUR DAC Connect a USB DAC and Fidelia drives it as cleanly as iOS allows. Every app on iOS goes through a fixed-rate system mixer at 44.1 or 48 kHz — no player can exceed it, whatever the DAC is capable of. What Fidelia does is reach that ceiling honestly: Bit-Perfect mode bypasses every processing stage for a clean, unity-gain path from file to DAC, and the readout tells you exactly what your DAC is receiving. Higher-rate masters are resampled by Fidelia's own reference engine — the same one that runs on the Mac — instead of by the system. (Keep the system volume at maximum for a transparent path.) YOUR MAC'S LIBRARY, OVER WI-FI Already run Fidelia on a Mac? Fidelia Bridge copies your albums, playlists, radio stations, presets and settings straight across your own network — nothing to find, nothing to import, nothing in a cloud. Keep chosen albums on the phone for listening without the Mac awake.

DSD plays via high-quality PCM conversion. From Audiofile Engineering — independent and family-owned.
