How Fidelizer Works
Fidelizer is very simple tool to use. You just have to choose optimization level, click “Fidelize”, sit back and listen to good music. You can also choose Customize to pick individual optimizations by yourself to find the optimal point with other optimizations. Fidelizer could do the following functions below.
You can choose any options you want freely because Fidelizer doesn’t make permanent changes to system. All changes will be reverted back to normal after system restart. So you can give it a try without taking any risks at all. There’s no chance to put system in harm.
Let’s see how system works before applying Fidelizer optimizations. To make things simpler, we’ll classify resource utilization to audio task and non-audio task. Based on Microsoft’s Multimedia Class model, we’ll treat non-audio tasks as System and Network, most systems would look like this.
We’ll divide everything evenly for easier understanding. You can see that part of audio is one big speaker icon on top playing multimedia files, part of system is middle graph doing background services and other non-audio tasks, part network is bottom globe with computer on network doing some web browsing and streaming content jobs. After optimizations, your system could probably be Fidelized like this.
As you can see that audio will have more resource utilization after using Fidelizer and can improve further with higher optimization levels. You can learn more about each optimization level in details from reading User Guide including individual options and features from upgraded version. Isn’t it great that you could improve Windows audio quality this much for free?
FOR FREE? REALLY?
Yes! You can get this for free with no trial because developer of this software wants to change the world of computer audio where most audiophiles pay for OS X audio software. The thought of OS X being best audiophile solution is unbearable while there’s so many contributions to Windows side such as:
JPLAY – Ultimate Audio Output module for Windows
AudiophileOptimizer – The best way to turn most powerful Windows platform to dedicated audio server
Rewrite Data – Data storage optimization for reducing jitter by Bughead Emperor developer
And of course, Fidelizer too. They’re made by truly passionate audiophiles.

Is there some kind of way to test it, before buying it?
While it’s understandable how some customers choose to evaluate test products before purchasing. However, we decided to focus on improving product quality and services without limiting features to test version. We don’t favor the idea of making trial version of Fidelizer Plus/Pro with limited capabilities and it later becomes constraints to further improving software.
Developer put great effort in building good quality software for free. So if you trust in free version’s performance being something worth paying for, you won’t be disappointed in what Fidelizer Upgrade Program can offer you. You can read reviews and how other customers say about Fidelizer after upgrading and make up your mind later.
Since moving Fidelizer to new home, there’re requests sending for product review from a few respectable audiophile websites. Some are kind enough to give us a review about Fidelizer products as below.
“Fidelizer resulted in the biggest single improvement to my hi-fi that I have yet encountered!”
What customers say about us
To ensure you’ll receive good quality of products and services, I’d like to share what customers say after applying Fidelizer Upgrade Program. These are quoted from their feedback without changing any context so feel free to read it.
A Fidelizer update is always great news for me. Since I use your program, the sound of my system has improved, enriched, expanded, the VERY BIG SOUND.
Thank you for your work, I am already looking forward to version 6.4.
Great job! I also had my brother & friend buy your product system never sounded better fast service. Dean from Canada! They are also very very happy with Fidelizer Pro worth every penny!!!!!!!!!!!!!
Excellent upgrade on your freebie! on mini 8 VHD of AOed Win2Go Server 2012 R2 Essentials OS bootloaded into RAM, player Lekt.exe out through RME HDSPe card. More detail, dynamics, everything – far exceeded my expectations of what is possible from red book.
Thanks for getting the program to me so quickly. I have had a few hours with it this this evening & WOW!! what a difference compared to the free version. I’m so glad I upgraded & I will probably go Pro next month when I have the money. Is it correct that I could do that for an extra $30? The bass is deep & tight now & the soundstage is wide & precise. The shear amount of small details i’d never heard before was amazing even though I have a decent system. Thank you for you hard work in creating this program & improving my listening experience by such a large margin
After upgrading to Fidelizer Pro
“Much more subtle changes this time but very nice one’s. The soundstage is fantastic, wide & 3D. Also, vocals are brilliant. Lyrics I could never make out are now clear to me without straining to grasp them. It’s taken the last bit of harshness from the treble & as a result female voices are smooth especially sopranos. I just want to keep playing my music now!!Mike.”
thank you very much for your quick response. I have just installed the Fidelizer Pro and it works just as expected. I am really impressed, how much difference the Fidelizer makes to digital audio. I always disliked the “digital sound” with its glare, graininess and simply sterile artificial sound. I even changed my music selection according to avoid the bad effects as much as possible. No more great female singers and so, because digital it just made it impossible to hear. But NOW THE MUSIC HAS RETURNED and I can listen to what I want and not what digital can reproduce without causing just pain in my ear.
I was using a pretty expensive vinyl record based LINN hifi system (with Linn LP12 record player), before having switched to digital and always missed something. Well, it’s here again, sounding like a very very good analogue recording to my ears – thank to Fidelizer Pro!
After several hours of using Pro, I’m very pleased with the purchase and am happy funding your endeavor.
I’m using an Apple Mac mini running Bootcamp, Windows 8 and JRiver Media Center in a headless configuration using JRemote.
thanks so much for generating the program so quickly this (my) morning. I downloaded in the meanwhile and did a bit of listening – so far: absolutely great! Even more transparency/veil off/details compared to the trial version and it feels like having a more precise low end. I never got close with my high-end CD player to what a properly setup and fidelized PC via DAC is capable of doing. Late night listening will follow, the first glimpse is great!
I’ve installed Fidelizer pro 6.1 on my HTPC and everything is OK.
Audio is very good, as I’m using JRMC 20 as VDM driver and DVDFab plyer for playing DVD or Bluray.
This little media player has a very good video quality equal to JRMC with Red October HQ filter and it offers menu for Bluray.
For the moment I’m using Audiophile level for Media Center (HTPC, Audio/Video/Network player), black are deeper with better definition and more “grain”.
Thanks for the 6.1 update to Fidelizer Pro. I tried this tonight and I am very impressed with the additional texture and detail this now brings to instruments. I have a JPLAY control/audio pc set-up and I have posted my impressions on the JPLAY forum (I am rocketiii).
Many thanks for your work,
I have used Fidelizer before (F4 & 5) with good results, see copy of a post from JPLAY below. After more listening today F6 is clearly a further improvement. F5 Extremist did not really work for my system, but with F6 the Extremist option provides a further significant improvement in SQ.
This seems to be working better, and it sounds better than ever. I think that if you don’t select the device you are using for sound as the default, it will be shut off. Only got to listen to it for an hour. Another step closer to analog with the best aspects of digital included. Lots of space and subtle details. You do know how to listen. Can’t wait to get my tricked out Geek Pulse DAC with 82 Femtosecond clock. Still need Fidelizer if the jitter is modulated by the computer.
My reaction to listening to Fidelizer 6.1 Pro is being relaxed, closing my eyes and listening. I can’t remember being able to do that before. Job well done.
I managed to get the program installed before I left for work. It sounds really good…smooth and musical.
I am very happy to get the Pro version without any regret, and 100% money worth. Thumb up. There is improvement with subsonic low and high frequency with much purity sound.
Great product! Really makes more different to the sound with my setup than ‘replacing all the cables’ Very pleased!
I really like with my Audio PC setting. With AudiophileOptimizer 1.30, it gives extra impact on sound. Current my best feedback setting is below…
– Client PC : Windows 8 (not 8.1) + Fidelizer Pro 6.1 + JRiver 20/JPLAY 5.2.1
– Audio PC : Windows Server 2012 + AudiophileOptimizer 1.30 + JPLAY 5.2.1
I think it is the best sound I ever heard with my Audio setting. Very clear background and close to perfect image (I assume there is no perfect with Audio since every new technique comes). Especially, when I listen big scale symphony like Mahler Symphony No.2, I can hear different stage of music. Better dynamics and better image. Thank you for great software.
I may need more time to conclude testing, but I can say Fidelizer Pro definitely help my PC Audio life.
Hi, Just loaded it and have it running now. It sounds great. Seems very smooth and resolved. I am running in Audiophile mode/JPlay local.
