It will increase audio thread priority, real audio thread not increasing process priority in Task Manager so audio performance is improved from its core.Īfter applying these core optimizations, your system should probably look like this:
#BEST UPNP SERVER FOR AUDI SOFTWARE#
Audio thread priority optimization: Here’s a real gem. This is the only unique feature that I couldn’t find any software claiming to do and it needs to be done from Core Audio’s API call. This would solve most low latency issues in digital audio.ģ. I added this to Fidelizer and set it to the lowest possible resolution (0.5ms).
I looked further and found it changed the kernel timer resolution from 15.6ms to 1ms, fixing this stuttering issue. I used to have stuttering audio for low latency playback but running this software stopped the stuttering. Kernel timer resolution optimization: I first discovered this from DPC Latency checker software.
Increase more frequent time slice for audio resource utilization.Ģ. Raise audio task priority, over all others, like I/O, etc. Keep audio tasks working steadily without losing focus to other tasks. At least you can find an explanation in Fidelizer and here’s how it’s done. Multimedia Class Scheduler Service (MMCSS) optimization: You may see some DAW software having MMCSS options and we have no clue what they do specifically, as if it’s the developers’ secrets. It focuses on applying Fidelizer’s core optimizations below.ġ. “Consumer” represents everyone who can use Fidelizer on any machine to improve audio performance without any drawback. After the optimizations, your system will have improved audio performance by concentrating available resources. Let’s see how Fidelizer works in the first optimization level. You can see that the audio is represented by the big speaker, playing multimedia files, the system by the graph, running services and tasks in the background, and the networking on the bottom, doing some web browsing and streaming content. We’ll divide the work evenly for easier understanding. Based on Microsoft’s Multimedia Class model, we’ll treat non-audio tasks as System or Network. Most systems would look like this.Īs stated in the picture, this data is simulated to help users visualize how system resource utilization works. This page will help you to understand how Fidelizer works in detail starting from each optimization level down to every single individual option.īefore we start, we’ll classify resource utilization into audio tasks and non-audio tasks. Audi dealerships will be able to provide you with further information on Wi-Fi audio players.Although Fidelizer is very easy to use, those features require a long explanation for people who aren’t familiar with tech stuff to understand how it works.Please note that files with DRM protection cannot be played by the Wi-Fi audio player.
