The main file that controls recording audio is created under build/mic_record_file Once it begins running, you have to hit ctrl+z to stop recording, otherwise it runs infinitely. Once you stop it, you'll have 9 different *.raw files. Each one is numbered and corresponds to a specific mic on the array. The 9th *.raw file is a beamformed channel from the other 8. Similarly, the *.wav files that are created will be named according to the channel they came from.
