Fidelia music player for OS X

Yet another new music player.  Audiofile Engineering, maker of the fine Wave Editor software which we covered in an earlier post, is launching a Fidelia, a Mac OS X music player which does upsampling and dithering on the fly using industry standard iZotope's algorithm. Seems like it has the best features out there.  We will be testing it soon to see how does it compares sonically to competing OS X players like Amarra, Pure Music, Decibel and Audirvana.  Beta testers who were using Fidelia under its previous "Twilight" name, reported excellent sound quality.



  • Fidelia takes advantage of Apple CoreAudio, Quartz, and other solid OS X features
  • Supports AIFF, WAV, CAF, AAC, Apple Lossless, Ogg Vorbis, MP3 and FLAC, also convert existing files to and from any
  • Seamless access by importing your iTunes library, including user-generated playlists
  • iZotope's 64-bit Sample Rate Converter featuring a hybrid ringing control enabling a compromise between the standard pre-ringing of a linear phase filter and the post-ringing of a minimum phase filter with unlimited sample rate support (including 44.1kHz, 96kHz, 192kHz, and higher)
  • iZotope's MBIT+ dithering algorithm (Audiofile Engineering claims that this is the best sounding dither on the market - making digital domain volume control a real contender for serious listening)
  • Fidelia remote app ($10 available from Apple Appstore) for iOS turns your iPhone or iPod touch into a full-featured remote control
  • $119 Price to be announced
Update: The base program is $20.00 The Advanced program that includes hog and advanced settings for iZotope SRC is an addtional $50 in the Add-on store.
