Gain Matrix 8x8 (APO As Application)

Postby Vincent Burel » Thu May 26, 2016 3:10 pm

With Voicemeeter Audio API, it is now possible to make APO's (Audio Processing Object) working as application.
The first example provided in the SDK is a 8x8 gain matrix applicable to a selected BUS.

The application registers his own audio callback as OUTPUT INSERT on Voicemeeter to get all audio output channels before going to master section (all 'C' source code available in SDK package).

I have found the gain matrix utility very useful. I sometimes need to quickly swap left & right channels. I was using Equalizer APO, but it's more of a hassle now.

I also made this AutoHotKey script that places a new button on VoiceMeeter Bannana to open the 8x8 Matrix window.
Make sure that vmr_matrix.exe is located in the voicemeeter install folder along with button.png. You also need to have AutoHotKey installed. Then just run vmbutton.ahk and it should appear on the right under the recorder.
