Its just all the same microphone signal coming through the DSP at slightly different mix levels.
Its not perfect , a couple of really small glitches near the beginning of the recording.
Going for perfect here so will have to find out what that is ! The TDM8 clk 12.288mhz and FS are just going down
jumper wires and are patched into a scope , so probably not helping at all!
I scrapped the TS screen now and start recording with the bluetooth app.
after i finish 24bit & 32bit I will move onto sending the realtime recording data back to the app including nearly real time audio meters from the DSP to the app.
I'm going to unscrew / disconnect the screen now, waste of space :)
