Description
Fidelia is a reference playback system for Mac: a complete, inspectable signal path from your files to your DAC, your headphones, or your whole multichannel rig. One purchase, no subscription. FOUR MASTERING-GRADE PROCESSORS, BUILT IN Equalizer — a ten-band EQ in Fidelia's own chain, with clip-safe automatic preamp and direct import of AutoEQ correction profiles for thousands of headphone models. HeadSpace — headphones are unnatural: your left ear never hears the right speaker as it would in a room. Frequency-dependent crossfeed modeled on real head acoustics gives a soundstage like speakers, not two drivers against your ears. Pro Dither — moving between bit depths decides whether the noise floor vanishes or turns audible. A 9th-order psychoacoustic noise shaper tuned to ISO 226 equal-loudness contours, the approach licensed into Pro Tools and Logic. Reference SRC — linear-phase and minimum-phase engines from professional mastering practice, with five quality presets. THREE AUDIO UNIT SLOTS Load any Audio Unit — EQ, convolution, room correction, spatial. Plugin GUIs open inside Fidelia; every setting returns as you left it. The slots run a bus up to sixteen channels wide, so a convolver can emit a filtered channel per driver. BIT-PERFECT & EXCLUSIVE MODE Source bits go straight to your DAC — no processing, no conversion. Exclusive mode locks the device to Fidelia, bypassing the OS mixer entirely, like dedicated audiophile hardware. YOUR WHOLE RIG, NOT JUST TWO CHANNELS Fidelia plays 5.1, 7.1 and 7.1.4 — up to 9.1.6, sixteen channels — reading the layout each file declares, not guessing from track order. The Output Dashboard puts the rig on one surface: your speakers drawn where they sit, your interface's outputs beside them, a live meter on each, so a miswired channel is obvious the moment music plays. Identify sweeps the room a speaker at a time; mute, solo and polarity sit on every speaker. Calibrate by measuring, not arithmetic: give each speaker the distance you measured and the nearer ones are delayed to match. Two subwoofers can differ — that's the reason to have two. Your rig is remembered per output device. NATIVE DSD DSF and DFF, DSD64 through DSD512, decoded in real time, gaplessly, no conversion. For a DAC that decodes DSD itself, bit-perfect DoP sends the stream through untouched, enabled per device. YOUR NETWORK, YOUR LIBRARY Fidelia speaks Lyrion (Squeezebox): your server's library sits in the sidebar beside your Mac's files — one search, one wall, one player. Browsing it is free. It plays TO your system, too. Any UPnP/DLNA streamer becomes an output — WiiM, Bluesound, Linn, Naim, Eversolo, Denon, HQPlayer — chosen from the same menu as your USB DAC, fed the original bytes, gapless. And you don't choose between the network and your signal path. Leave bit-perfect off and the whole chain runs first — HeadSpace, dither, resampler, your Audio Unit slots — then streams the result. Most network players hand the file to the box and stop. BUILT FOR LARGE LIBRARIES Album art fills itself in, exact matches only — a wrong cover is worse than a missing one. Every playlist remembers its own sort, and duplicates resolve to the best copy you own. ALSO • Internet radio — thousands of stations or any URL, quality graded • Gapless rebuilt from the ground up — no gaps or clicks, even across sample rates and DSD • Conversion to AIFF, WAV, FLAC, Apple Lossless, AAC, CAF • Monkey's Audio (APE) import, Music.app library sync • Scalable player — 5 sizes plus a scale control to 200% FORMATS WAV, AIFF, FLAC, Apple Lossless, CAF, MP3, AAC, OGG Vorbis, Opus, AC3, Wave64, Sound Designer II, AU/SND, DSF, DFF. PRICING — NO SUBSCRIPTION Free to try for 14 days, the full app, no limits. Then a one-time unlock. Network playback — Lyrion libraries and UPnP streamers — is a separate one-time unlock; browsing your server is always free, so you see your library working before you decide. Fidelia Remote, the iOS companion, is free.
What’s New
Version 2.12.18 · 9/19/2026Bring your playlists. Import M3U playlists from other players from the File menu, or drop them onto Fidelia or its Dock icon. Fidelia finds every track it can — even from a playlist made on another computer, or before you converted your music — and tells you plainly about any it can't. Take them with you. Export one playlist, a selection, or all of them at once, ready for another player or kept as a backup of everything you've arranged. Your covers come first. An album's own cover, in its files or its folder, always comes first, then your own music servers, and only then the web. With online lookups switched off, Fidelia still reads every cover you already have, and Find Artwork runs whenever you ask. Also in this release: pausing, or a brief network hiccup, never cuts a track short on a network streamer, and each track ends precisely where it should before the next begins. Longtime Fidelia 1 owner? Fidelia 2 is an all-new app — a free download with a 14-day trial and a one-time unlock, no subscription, so a Fidelia 1 purchase won't restore into it. Thank you for years of listening.
