I'm asking this question to help out a user on a sister SE site.
I'm Mac-based myself & know this is an easy task in Mac, using CoreAudio, SoundFlower, Rogue Amoeba etc.
Is there a comparable Windows framework that would allow audio processing plugins to be inserted to the 'standard' Windows audio chain, for non-professional use?
The end requirement is for a user with a specific hearing impairment who needs to be able to sum stereo to mono, adding different EQ to each channel before summing ?
This is a consumer-level, output-only requirement & needs to be done without recourse to any kind of DAW or offline processing.
My Google-fu is usually pretty good, but I'm having difficulty getting past all the VST plugin pages to find what I'm looking for.
