This repo contains a 64-bit port of EqualizerAPO - system wide equalizer for Windows. Standard Equalizer APO performs all sound processing using 32-bit float number. This is a modification of the processing engine that uses 64-bit double precision numbers instead. This increases fidelity especially with complex configuration files (like configurations generated by HeSuVi).
No functionality was added or modified. The source code is based on commit r73 of the original repo.
