Fidelizer


For anyone interested in optimizing their Windows-based (HT)PC music source I wholeheartedly recommend downloading the free(!) "Fidelizer" program via below link(download option at the bottom of the page):

In short Fidelizer optimizes/economizes the environment on your (HT)PC, which can be done in three stages by shutting down processes not important to anything other than (roughly) the most basic needs with regard to A/V playback. As it says on their homepage:

Fidelizer has 3 optimization levels. They're all for the same goal to sonic improvements. I'll leave them all to your judge whether they're subtle or big difference. At any rate, you should leave your ears with it for at least week if it doesn't hurt your computer. Some people need time to adapt to changes.

The first ones is 'Professional'. This will optimize system to the extend that it won't significantly affect overall system performance. You can work as usual while enjoying improved multimedia experiences.

The next ones is 'Audiophile'. This is quite dedicated ones for those who pursue higher fidelity. It will lower system/network performance so audio can gain more priority to access to resources at time. It will also lower most processes including system ones to lowest level so you need to close your audiophile player before using it.

The last ones is 'Extremist'. As the name say, this isn't risk-free feature to try. It will stop most bundled system services leaving only important ones for audio. Yes, it will stop network services and such too. You may not know but Windows Audio and DHCP share the same process in service host provider so disabling network can significantly improve sonic performance. I also add some options to keep network and user experiences (HID,Tablet,Themes) working for some applications.

For general use, you should stick with 'Professional' level but computer in today's market should be able to use 'Audiophile' without hassle about system/network performance. I use 'Audiophile' level on AMD Phenom X2 550 BE machine and ended up running fine for 24/7 usage.....ya it's old and cheap unlike i7 or Athlon II X6 but it still works.

I'm using the 'Audiophile' level myself, and have experienced no problems at all nor any noticable limitations in the use of my HTPC. One of the people who was lead to Fidelizer via my initial recommendation(I stumbled upon Fidelizer from a recommmendation over at the JRiver forum) is a software programmer himself, and he's successfully tested Fidelizer quite thoroughly to see whether any glitches should occur that might be detrimental to the overall funcionality of the PC. As it's stated on the homepage any "newer"(even over 5 years, I suppose) computer shouldn't experience problems with the use of Fidelizer.

Taking up only 272kb Fidelizer has provided a noticable sound quality improvement not only in my setup, but also in all the setups of the audio-friends of mine to whom I've recommended the download. One of them even goes to say he's hardly heard a more substantial sonic upgrade in a long while(to which I definately agree), and with this in mind think about the following: Fidelizer is FREE!

Indeed I'm perplexed that this little wonder of a free program hasn't received more attention among the computer audiophiles, at least what I know of, and I certainly don't see any reason going about hiding its presence.

So, without much further ado: go ahead and download Fidelizer ASAP. Any questions, be they with regard to download/use or anything else, are welcomed.

I wholeheartedly agree. It's one badass upgrade - bigger improvement than some $$$ improvements I have made. If it doesn't work for you its very simple to delete, anyway.
waste of time. Jplay blows fidelizer out of the water, assuming that you play lossless vs midfi quality audio files
Davide256 --

All lossless WAV files played here, and via my quite
transparent setup Fidelizer is certainly not a waste of
time; it makes a very worthwhile difference with JRiver
MC18, and that for free. I'll just go ahead and say it
again: Fidelizer makes a VERY worthwhile difference, not
only in my setup.

Your "JPLAY blows Fidelizer out of the water"-
remark is, strictly speaking, somewhat besides the point;
Fidelizer is no playback software but a Windows-based (HT)PC
optimization tool, and as such makes comparisons to a
playback software moot. If you'd want to compare investments
- one free, the other not - into making better sound, I'd
say Fidelizer with an existing playback software like JRiver
MC18 holds as much potential as JPLAY sans Fidelizer, unless
perhaps where JPLAY's hibernation mode comes into play.
Indeed, being that Fidelizer is free and does what it does,
why not use it in conjunction with JPLAY as well?

No bashing on JPLAY, I must add. In terms of pure 2-channel
sound quality I find it's possibly the very best out
there, certainly in hibernation mode, but JRiver MC18
+ Fidelizer is very close. There's also cPLay, which is
free, and to my ears sounds very much like JPLAY. What I
like about the sonic "imprinting"(or lack hereof)
of cPlay and especially JPLAY is the natural, full-bodied,
and organic sound, where JRiver MC18 sans Fidelizer is
perhaps a wee bit more meager or even sterile, if you will.
However, Fidelizer seems to almost completely eradicate this
slight sterility via JRiver and brings with it a needed
organic element to the sound.
Phusis, you don't post your system but I see from one of your threads that you use the NuForce DAC-9... this has USB but its not listed as asynchronous. Without asynch usb computer audio is a lame duck. I run a PS Audio DLinkIII with the JKMkIII asynch USB converter. My PC server is optimized per computer audiophile service specs with the exception that network services are enabled

Running a quick A/B comparison of Fidelizer in extremist mode vs Jplay in Xtreme mode

RR -120 CD lead track,Brittens Orchestra
both harmonically correct. Fidelizer soggy on bass attack. Jplay deeper in bass with good attack. Fidelizer flat lifeless stereo image. Jplay presents good bloom for brass instruments spatial location

Paper Airplane by Alison Krauss and Union Station - lead track
both harmonically correct. Fidelizer flat and uninteresting. Jplay captures picked string leading transients and the richness of the acoustic guitar.

I will knock Jplay because it takes 6 seconds to respond to a mouse click once music starts playing in extreme mode, but I can live with that to get Porsche vs familiy sedan performance.
