passing audio to libpd4unity

[JohnnyMauser]

I have following problem: i want to process microphone audio in Pd send from Unity using the given LibPdFilterRead.cs. it is working in that way that i can receive audio from unity, but Unity is sending aparently all incoming audio back to Pd, so that there is a loop now. That way, I cant use my pitch tracker on only the incoming micophone signal but get crosstalk from my Pd Audio source. What i want is only send the microphone input to Pd, nohting else. Any Ideas?
