User Guide – How to improve sound quality with Fidelizer

This will help you setup your system for better sound quality with Fidelizer. Please follow the step-by-step instructions below.

 

 

System Requirements

 

Although Fidelizer could work on all versions of Windows since Windows XP without minimum hardware requirements, some users might feel confused whether Fidelizer will work on their installed version of Windows. Fidelizer is supported on the following Windows versions:

Windows XP*
Windows Vista
Windows 7
Windows 8
Windows 8.1
Windows 10

Fidelizer also works with the following versions of Windows Server:

Windows Server 2003*
Windows Server 2008
Windows Server 2008 R2
Windows Server 2012
Windows Server 2012 R2
Windows Server 2016

* Some NT6 core optimization features aren’t available in these marked Windows versions. To get full optimization, consider upgrading Windows.

 

For usage with AudiophileOptimizer, please enable the following options in AudiophileOptimizer (Recommended version 1.31 or higher)

– Keep Windows Management Instrumentation service
– Install Kernel-Streaming and MediaPlayer Support
– Enable MMCSS in core mode (Multimedia Class Scheduler)
– Set Fidelizer Pro as default shell replacement (Only after optimizations and you don’t see Fidelizer Pro running on startup)

 

 

STEP 1: Setting up the audiophile environment

 

Although Fidelizer can instantly enhance Windows sound quality with just one click, setting up audio software for better sound before using Fidelizer is recommended. To demonstrate how to improve sound quality on audio software, we’ll use foobar2000 as an example.

 

1. Download and install foobar2000 with WASAPI component for bit-perfect playback support

2. Open setup Preferences and set ReplayGain to “none” in Source mode and Processing as shown below.

 

Fidelizer - Foobar Setup 1

 

3. Setup output device with WASAPI (event), change output data format to highest supported bit-depth, and slide down Buffer length to 200ms. If you have working ASIO driver, you may install ASIO plugin and use ASIO output instead.

4. Configure Advanced settings with the following options:

Full file buffering up to (kB): Highest possible (I entered 1048576 for 1GB buffer)
WASAPI Hardware buffer in MS – push/event mode: 24
High worker process priority: checked
Thread priority: 7
Use MMCSS: checked
MMCSS mode: Audio (Windows default mode where Fidelizer optimizes)

 

Fidelizer - Foobar Setup 3

 

With this, you should get better sound from foobar2000 and make Fidelizer optimizations become much more effective than before. Some people who failed to notice improvements with Fidelizer before may have a better chance after configuring audio software like this.

 

For Tidal/YouTube users who rely on default Windows audio playback, you can setup bit-perfect sound software like VB-Audio ASIO Bridge with JPLAY/ASIO4ALL in combo for better audio performance. It also works well on iTunes and Windows Media Player.

 

 

STEP 2: Choosing user level

 

Fidelizer has 3 user levels. This will explain how each level affects your system.

 

Consumer: This is a default user level. Fidelizer will enhance sound quality without affecting system performance. Your system won’t slow down and everything will work fine as usual. I also use it on my work machine generating Fidelizer for customers.

Audiophile: This is a dedicated audio level. Fidelizer will sacrifice system performance for better sound quality. Your system will be slower and some applications may not work right. It doesn’t affect software running after optimizations but keep in mind it’s not suitable for work machine.

Purist: This is an extreme purist level. Fidelizer will stop/disable system services that aren’t related to audio playback. Services like Windows Update, Print Spooler or even network may stop completely depending on configuration. Don’t ever use this on work machine, you have been warned.

 

You can restart to return back to normal if you have trouble. For Fidelizer Pro, please run again, select Consumer level and Fidelize before restart.

 

 

STEP 3: Choosing configuration for the right application

 

In Fidelizer Pro, you can change your machine configuration for different suitable audio applications. Since they’re already explained in About Fidelizer section, this section will cover end-user scenarios, as below.
