Fidelia is the best sounding music player app available! Use your favorite plugins while listening.

Fidelia is a high-definition audio player for sophisticated music lovers. With support for all contemporary audio file formats and an elegant interface that focuses exclusively on music, it gives users the power and the freedom to organize, customize and savor their digital music collection at the highest possible fidelity in any circumstance. If you've invested in premium audio hardware, you should have the best audio software.

Fidelia provides a gateway to high-definition audio by supporting a wide range of high-quality formats — including FLAC, which iTunes does not support. As artists in every genre increasingly turn to high-quality formats, Fidelia gives discerning listeners a way to hear their music as it was meant to be heard.

Fidelia's stylish interface reflects users' pure passion for music, paying tribute to the iconic stereo systems of decades past while offering sleek, intuitive controls that Mac owners demand. A classically styled volume dial is augmented by Mute and Dim functions. A crisp, eye-pleasing display shows individual track details, stereo levels and audio waveforms. Fidelia also provides seamless access to your existing iTunes music library.

With Fidelia, savvy music lovers have the ability to further personalize audio playback by installing third-party Audio Unit plug-ins. For example, Fidelia reaches beyond the narrow parameters of typical built-in equalization controls, allowing users to install higher-quality EQ and other Audio Units plug-ins to suit any taste or listening environment.

With the Fidelia app for iOS (sold separately), users can turn their iPhone, iPad or iPod touch into a full-featured remote control for Fidelia.

NOTE: Fidelia cannot support DRM-protected files.

TourPooch ,

Best audio player. Period

I am an audio professional that deals with all kinds of formats of audio files. This is the only audio file playback piece of software that plays them all easily and has a good interface. I highly recommend it. I was super bummed when it was unsupported for a few years. NOW ITS BACK and there are regular updates through the apple store. This is the only stereo audio playback software you need.

Excellent sound, except has quirks.

This is probably the best sounding music library/playback software available, but the program has quirks and needs to be developed more. For one thing, everytime I import an audio file into the program, the file sounds different in the program. Don't know what's going on with that, but it's maddening. The other issue is the playlists you create aren't listed in alphabetical order, so if you have created a lot of them, it can be impossible to find the playlist you're looking for. Also, there's no way to see folders of each individual artist. I am a professional audio engineer, and I require excellent sound, and to my knowledge Fidelia is the best (I own the top 4 hi-fi music library programs for Mac), but this program needs to be developed more. I would gladly pay a ton of money for a better designed program, since I listen to music constantly and I need it to sound great.

New review

In my last review I complained about the pop up frequently of the review the product prompt…an then something amazing happened… I got a reply… from the developer first let me state that I do like Fidelia better than the app that came with my OS I sounds better to me an has much more control of the sound… I did run into a small hitch… sometimes it won’t play after my computer wakes up.. anyway the developer looks at the reviews so maybe there’s a fix on the way…I support small business this is a small company I would recommend there app …

Hey sorry about that, we are a small family-owned company and reviews go a long way toward getting visibility for our work. We will check the algorithm to see if we can tune it a bit. I hope you enjoy Fidelia!
