I am calling
AudioRecord.getMinBufferSize(44100,AudioFormat.CHANNEL_IN_MONO,AudioFormat.ENCODING_PCM_16BIT)
and using the returned minAudioRecordBufSize in
new AudioRecord(MediaRecorder.AudioSource.MIC,
44100,AudioFormat.CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT, minAudioRecordBufSize);
Is that sizing the buffers correctly?
Thanks for the offer for the enumeration app, but I do not have a failing
device at my disposal. Only a few devices are failing, and they are all
owned by my customers. I can't ask too much of them in the way of
debugging help.
