Forgive me for I have sinned.

 There is something somewhere about not making an oath.

Well, as I cobbled demo code together for the ADC submission (one
trial strategy was to use the demo API look and feel by deleting all
the elements not needed), experiencing 19% errors causing reboot on
the evening of the 14th, I made an oath: "I will not touch this until
I can load a clean new SDK."  -predicting that a new one would be out
in a week or so. Time passed. The future was not as I predicted. The
lawn is mowed. The dog is in great shape again... not at all snippy...

Please, please, I have learned my lesson. Oaths imply one can predict
the future. Clearly not true for me...

New SDK please.

1. AudioRecord: onPeriodicNotification and onMarkerReached are not called

I've seen posts regarding problems with the AudioRecord
OnRecordPositionUpdateListener, but I haven't seen any real answers.

I'm using AudioRecord to record from the mic, and I want to get the
input from the mic periodically so I can check sound levels and update
a meter.  I set up the listener like this:

        private OnRecordPositionUpdateListener mRecordListener = new
                public void onPeriodicNotification(AudioRecord recorder) {
                                mAudioBuffer = new short[8000];
                                mSamplesRead =, 0, 
                                if (mSamplesRead > 0)
                                        // do something

                public void onMarkerReached(AudioRecord recorder)
                                mAudioBuffer = new short[8000];
                                mSamplesRead =, 0, 

I instantiate the AudioRecord object like this:

                        // audioSource = MediaRecorder.AudioSource.MIC
                        // sampleRate = 16000
                       // channelConfig = AudioFormat.CHANNEL_IN_MONO
                       // audioFormat = AudioFormat.ENCODING_PCM_16BIT
                       // bufferSize = 409600

                        aRecorder = new AudioRecord(audioSource, sampleRate, 
audioFormat, bufferSize);
                        if (aRecorder.getState() != 
                                throw new Exception("AudioRecord initialization 

What happens is that onMarkerReached gets called once, after the
recorder is released, so that's not very useful.

Do I need to change the marker position and notification period?  Is
the listener working?  Is there another way to accomplish periodically
getting the mic input?


2. AudioRecord creates a stereo file instead of a mono file.

Yes its a bug, sounds like the WAV header is wrong. You'll have to
hack at that source to fix it..
