Fidelizer is a tiny and portable piece of software that can improve the audio quality of your system. It is simple to use and does not apply permanent modifications to the PC.
Since there is no setup pack available, you can drop the executable file anywhere on the hard drive and run it. Otherwise, it is possible to put Fidelizer on a USB flash drive or similar storage unit, in order to run it on other computers.
What's more important is that Fidelizer does not work with the Windows Registry or leave files behind on the hard drive after removing it.
The utility's interface is represented by a regular window with a well-organized layout. There aren't many configuration settings available, but the few ones are pretty powerful.
Fidelizer offers three optimization modes, and each of them has its own ups and downs. The "Professional" mode improves the multimedia activity without significantly affecting the overall performance of your computer.
The "Audiophile" profile is specially designed to bring you a better audio quality, meaning that the memory allocated for system and network processes is significantly reduced, in order to assign a higher priority to audio players. The last optimization mode, "Extremist", comes with a few risk factors for the computer, as it shuts down all services to provide maximum resources to your audio experience.
However, before resorting to one of these profiles, you may be interested in customizing the optimization mode when it comes to Fidelizer's core system and resource scheduler, processor core source assignment for multi-core optimizations, and advanced system or network process resource priority optimization.
In addition, you can stop unneeded services and just leave the ones related to audio, as well as keep network features and user experiences. Applying all these settings is easily done, with the click of a button, but a system restart is in order.
Fidelizer is light on the system resources and delivers good results in regard to the audio quality. We have not experienced any problems during our evaluation; the tool did not hang, crash or pop up error dialogs. Avid music fans are free to test Fidelizer for themselves, as long as they know what they are doing.
