LairdTurnerSpecial 0 Posted March 18, 2021 Hi! I wand to build an application were I can route the audio from the internal mics to an buffer. I've build some extensions to the current wrappers from Embarcadero for AVAudioSession, Audio.Toolkit etc. Currently I'm able die initialize an AudioSession, create the appropriate routes and select a specific mic and create an AudioUnit. Everything seems to be okay. No function returns me an error, When my app starts on the iPhone I get a message that my app whants to access the mic. but the audiorender callback doesn't get called. Can somebody help me with my problem. Have someone programmed something similar. Thanks! kind regards René Share this post Link to post
