Some people asked since few months ago if Fidelizer development is still active and yes it is. I have some internal updates over time and don’t save features and optimizations to prolong version releases.

Now version 8.6 is ready with some changes and optimizations applied. I waited until Windows 10 with 20H1 update released first to confirm further changes and launch it with some bug fixes improvements.

Recently I have a client using Sonarworks as DSP sound card so I also added Sonarworks apps to be recognized as audio processes too. I also added option to preserve current Processor Priority Policy as requested. 🙂

After publishing Fidelizer update, I’ll focus on updating portable products project a bit so expect something good for portable audio soon. 🙂

Hi. Since releasing version 8.4, I’ve been very busy with a lot of product research and development projects while maintaining Purist ROM updates. Now I finally have time to maintain Fidelizer updates for next release.

Version 8.5 will now support AIMP/AlbumPlayer/Amarra/Audirvana/MusicBee/Winamp software. Plus and Pro version will handle new services added from Windows 10 May 2019 Update too.

After fixing reported bugs after each big update, I can finally keep up with program compatibility and Windows updates on this release. I’ll launch some major new products soon and they’ll be game changer improvements for audiophiles. 🙂

It’s been a few months since last 8.3 release. I’m glad to see the hardware key being resolved finally. I’ve been improving Fidelizer software since last release and now it’s stable and ready for official version 8.4 update involving bug fixes and improvements.

Version 8.4 will now support Logitech Media Server (aka. Squeezebox) software. It will also prompt for “Music Player Application 1-3” to avoid the confusion when browsing software.

There’s also immediate fixes after 8.3 like 24-core processor support that I patched again after proper release in Plus/Pro version which will officially be addressed in version 8.4. Higher optimization levels will not affect system/audio performance as much as before too.

Changelog for version 8.4

Free
-Added Media Player Application order 1-2-3 when browsing for each file
-Improved compatibility with Logitech Media Server software
-Improved system/audio stability on higher user level optimizations

Plus
-Added Media Player Application order 1-2-3 when browsing for each file
-Fixed multi-core optimizations on some cases with more than 16 cores processor like 24
-Improved compatibility with Logitech Media Server software
-Improved system/audio stability on higher user level optimizations

Hello everyone. After releasing version 8.2, I spent most of my time fixing the remaining issues with fidelizer.key generation algorithm. I’m truly sorry for the trouble all these times but version 8.3 will have full coverage of fidelizer key data fixes now.

In this release, the older keys you got before will still work as long as associated hardware is still present. This will fix issues with Windows Update and different hardware device order issues on dual boot for good.

While fixing the key generation algorithm, I also realized the root cause with Windows Server in core mode. The reason is fidelizer as a shell may run before important services sometimes and I made sure they’ll run properly now.

I also fixed 32-core processor bug issue that happen after releasing version 8.2 too. This issue has been fixed internally for a long while because it breaks functionality and I’m glad to see it’s officially addressed and resolved in 8.3.

Last month I found a rare gem called Audiophile uPNP Renderer. It’s true audiophile uPNP streaming platform playing only FLAC/WAV/AIFF format. It sounds really good for free software. Sadly, it doesn’t support DSD and ASIO but you can mix with VST too.

I also added new applications into compatibility list including new JPLAY Femto release and some new apps requested from clients. Windows 10 updates that have more processes related to audio performance will be handled properly now too. 🙂
