About
Fidelia is an audiophile music player for Mac.It plays music exactly as it was recorded: without compression, loss of quality or compromise.Version 2.0: Completely redesigned, with built-in studio-grade DSP engine.
Fidelia 2.0 includes three DSP processors that sound engineers pay hundreds of dollars for as standalone plugins.They are built into our player absolutely free.
HeadSpace - frequency dependent processing for headphones.Listening to music with headphones is unnatural for hearing.In real life, the left ear should hear the right speaker, and vice versa, but this does not happen with headphones.HeadSpace corrects this with a frequency-dependent crossfeed modeled after the acoustics of the human head: bass penetrates 90%, mids 50%, treble 15%.The result is a soundstage that resembles the sound of speakers in a room, rather than two speakers pressed to your ears.
Pro Dither - psychoacoustic noise shaping (noise shaping).When changing the audio bit depth, it is the dithering that determines whether the noise threshold disappears or becomes audible.Fidelia uses 9th order psychoacoustic noise shaping tuned to ISO 226 equal-loudness curves, the same approach used in dither processors licensed for Pro Tools and Logic.The noise level drops below the threshold of audibility.This is professional mastering level dithering built right into the player.
Reference sample rate conversion.If your library is recorded at 96 kHz and the DAC is running at 48 kHz, the quality of the resampling is critical.Fidelia uses linear-phase and minimum-phase resampling engines - exactly the same as in Reaper, Audacity and professional mastering studios.Fidelia has both algorithms built-in with five ready-made quality presets and the ability to fine-tune manually.
Bit-Perfect and Exclusive Modes.In Bit-Perfect mode, the source bits are transferred directly to the DAC - without any processing or conversion.Exclusive Mode completely blocks audio output for Fidelia's needs, bypassing the macOS system mixer.Just like a stationary audiophile player.
3 slots for Audio Unit plugins.Load any Audio Unit plugins installed on your Mac into one of three effects slots.Equalizers, reverbs, compressors, spatial processors, whatever.Enable, disable, and open the plugin GUI without leaving Fidelia.The state of presets is saved between sessions.No other independent player can do this.
Designed for large media libraries.Version 2.0 added batch search for album covers.Select untagged tracks, select Find Artwork Online, and Fidelia will find, download, and embed art for the entire list.And if you want, just drag and drop images into the Now Playing panel to create cover art for your entire album in one click.For a huge collection of rips, this saves tens of hours of routine work.
What else does version 2.0 have in store:
• Playback without pauses (Gapless) has been completely redesigned - no delays or clicks at the junctions of tracks.
• Multi-channel routing (up to 48 channels) for working with professional audio interfaces.
• Convert formats to AIFF, WAV, FLAC, Apple Lossless, AAC, CAF.
• Import DSD (DSF to Apple Lossless 24 bit / 176.4 kHz) and Monkey's Audio (APE to Apple Lossless) - your entire media library in one place.
• Synchronization with the Music application library (Music.app).
• 5 player sizes, including mini player.
• Fully customizable hotkey combinations.
• Sticking of player and library windows - the collection window is docked with the main window and follows it.
Supported formats:• Lossless: WAV, AIFF, FLAC, Apple Lossless (ALAC), CAF.
• DSD: DSF (imports and converts to Apple Lossless 24bit/176.4kHz).
• Lossy: MP3, AAC, OGG Vorbis, Opus.
• Also supported: AC3, Sound Designer II, AU/SND, Wave64.
APE files are converted to Apple Lossless upon import, maintaining the original sample rate and bit depth.DSD (DSF) files are converted to Apple Lossless 24-bit/176.4 kHz upon import—a high-end audiophile conversion without loss of quality.
