fidelizer will instantly turn your windows xp/vista/7/8 computer to audiophile workstation for sophisticated audiophile player like j river, xxhighend, hqplayer, foobar, etc. it involves no permanent modifications so system will remain safe and sound after restart so even system with normal windows installation can experience better sound quality when needed. backgrounds behind the optimizations is far advanced for someone daring to make free software so grab it while it lasts.
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 riskfree 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.featuresstop most system services leaving only audiorelated onesoptimize audio thread, i/o priorities, clock rate in resource scheduler
