    Record and process audio

    Hello there, I am trying to develop an iOS app with Rio. This app must record audio and process it in real time to display some graphs. I am a newbie with FMX platform and iOS, there are lot of informations I don't get There is iOSapi.AVFoundation unit which contains a lot of types (TAVAudioSession, TAVAudioRecorder) but I cannot understand how to use them. For what I understand, I have to define an audio format (2 channels stereo, 16 bits), get the buffer size, create a recording task and then launch recording. In a thread I read samples and fill them into a TMemoryStream for processing. Do you think is this correct ? Do you have any idea how can I do this ? Kind regards Lefjucabro
