• Process optimization. Fidelizer analyzes and manages background processes, disabling those that are not essential for audio playback. This includes system services, background applications, and scheduled tasks that can cause interference.
• CPU priority. Assigns higher processing priority to audio applications, ensuring that system resources are primarily dedicated to playback. This reduces latency and improves audio stream stability.
• Core isolation. Allows reserving specific processor cores exclusively for audio tasks. This feature prevents other processes from consuming resources on the designated cores, improving performance.
• Memory management. Optimizes RAM usage for audio applications, reducing swaps with the paging file. This decreases delays and improves system responsiveness during playback.
• Service disabling. Identifies and disables Windows services that are not necessary for audio playback, such as automatic updates, file indexing, or unnecessary network connectivity.
• Exclusive mode. Configures the system so that audio applications run in exclusive mode, avoiding signal mixing or resampling by the operating system.
• Latency reduction. Implements specific adjustments to minimize latency in the playback chain, from the application to the DAC output.
• Network optimization. Disables network protocols and services that can introduce electrical noise or consume system resources during local playback.
• Power configurations. Adjusts system power profiles to avoid CPU throttling and maintain consistent performance during high-quality playback.
• ASIO compatibility. Improves ASIO driver performance by optimizing buffers and interrupt priorities, reducing clicks and pops during playback.
• Advanced customization. Offers options for experienced users to adjust specific system parameters according to their audio setup needs.
• Presets. Includes predefined modes for different uses: music playback, audiovisual production, or gaming, with optimized settings for each scenario.

Fidelizer was initially developed in 2012 by Fidelizer.Audio, an audio engineer and high-fidelity enthusiast. The project was born as a response to Windows limitations in audiophile playback. The software is written in C++ with assembly components for low-level optimizations. Over the years, it has received regular updates to support new versions of Windows and optimization techniques.
