 Example for using the microphone with ctrulib. Hold down the A button to record, the app will then play the recorded audio once the A button is released. Roughly 32 seconds of audio can be recorded with the default audiobuf size in this app.
 
+Do not use this example(and/or ctrulib MIC?), since MIC is broken currently.
