I have just joined the group. I am working on a I am having

I want to use different techniques.
In short need a way to get sound data in bytes if possible float and
an ability to process it.
Can somebody help me with finding an easy technique for accessing
voice from the internal microphone ?
Take a look at TN2091: Device Input using the HAL Output Audio Unit
