Fidelizer 6.2

Fidelizer 6.1

Enjoy music with Fidelizer? Consider Fidelizer upgrade program

Fidelizer will instantly turn your Windows 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 a free software but I was pissed with Mac audiophile zealots back then so I made this on a whim to show them how easily Windows can get better sound.

How Fidelizer works

FIdelizer will take advantages of MMCSS to handle multimedia in favor of better audio playback. It will also optimize other parts of system as below depending on level of optimization you choose before clicking ‘Fidelize’.

-Optimize audio thread, I/O priorities, clock rate in resource scheduler
-Optimize network utilization for low latency streaming media
-Optimize process thread priorities and system clock resolution
-Optimize processor core assignment for multi-core CPU
-Launch audiophile player with Fidelizer optimizations
-Stop most system services leaving only audio-related ones

This process are done on runtime so without making any permanent changes to the system except Fidelizer Pro that was designed for dedicated music server solution.


Configuring Fidelizer

Fidelizer has 4 optimization levels to choose. Default will be Workstation for normal use.

Workstation (For general purpose) – It’ll apply only ‘Fidelizer’s core system and resource scheduler optimizations’ This is key feature of Fidelizer and every Windows should have it.
Network streaming (Slower system) – It’ll optimize core optimizations in favor of network audio. It also reduce priority of non-audio processes to improve audio performance.
Audiophile (Slower system/network) – It’ll optimize core optimizations in favor of pure audio. It also reduce priority of non-audio processes and re-assign core affinity to improve audio performance.
Extremist (Full optimizations including stopping system services) – This will perform like Audiophile optimization level but also stopping system services. If you need to keep some services, choose Customize and select either Network features/User experiences.
