OVWrap stands for OpenVINO Wrapper. It is used for AI / neural network features like AI Noise Cancellation (running inference via Intel GNA/NPU/CPU) As far as I understand
The DFX Audio Enhancer is much better; you have extra modes : 1. Listening Environment´s with 2 options as selection: 1. Speakers and 2. Headphones 2. Processing Mode´s : 1. Music Type I 2. Music Type II and 3. Speech DFX Audio Enhancer was made from the father (the founder). FxSound is still maintained by the son from the founder from DFX Audio Enhancer. ps: The name is the game(the sound) changer.
once you set environment yourself with existing options like bass, 3d , ambience , you dont need processing modes like music type 1 and 2 etc. i never needed them to change. your wish if you want to stick to old crap. i also took so many years to move to fxsound from dfx. i adapted to it now. if the app working is important. not that father, son or brother did it. apps always update with more features. you are missing.
