Updated release of EqualizerAPO x64 1.4.2 with double precision processing and AVX2/AVX512 support. Should improve quality for complex setups, convolution filters, etc.
Note, Updated and tested with a simple VST2 plugin, should be compatible by using single precision processing before passing audio to VST's, converting back to double on return.
Requires at minimum a CPU with AVX2 support, anything from 2013 (Haswell) onwards for Intel, and anything from 2015 onwards (Excavator/Ryzen) for AMD. An additional version is available for AVX512, compatibility with AVX512 can be checked here.
Compiled this version with the latest Visual Studio C++ 2022 compiler, latest Windows SDK. Additionally used /fp-precise, and various optimizations flags for maximum speed without sacrificing floating point precision.
Installation
- You will need standard Equalizer APO 1.4.2 installed on your system.
- Disable Equalizer APO for all audio devices via the Equalizer APO Device Selector.
- Unpack the downloaded zip into the Equalizer APO installation folder. This will replace EqualizerAPO.dll and other related files.
- Re-enable Equalizer APO for any relevant audio devices via the Equalizer APO Device Selector. This will load the modified 64-bit audio processing engine for immediate use.
If you have a missing DLL error, make sure you have installed the Microsoft Visual C++ 2022 Redistributable from their website here.
Once installed it's recommended to ensure your EQ is fully functioning (enabling/disabling filters should change the sound, try adjusting your preamp as an easy test). If you have any issues, I recommend uninstalling EqualizerAPO (and Peace GUI if you have it), then following the installation instructions from Step 1 for a clean install.
