Remarks
Builder class for AudioRecord objects. Use this class to configure and create an AudioRecord instance. By setting the recording source and audio format parameters, you indicate which of those vary from the default behavior on the device.
Here is an example where Builder is used to specify all AudioFormat parameters, to be used by a new AudioRecord instance:
AudioRecord recorder = new AudioRecord.Builder()
.setAudioSource(MediaRecorder.AudioSource.VOICE_COMMUNICATION)
.setAudioFormat(new AudioFormat.Builder()
.setEncoding(AudioFormat.ENCODING_PCM_16BIT)
.setSampleRate(32000)
.setChannelMask(AudioFormat.CHANNEL_IN_MONO)
.build())
.setBufferSizeInBytes(2*minBuffSize)
.build();
If the audio source is not set with #setAudioSource(int), MediaRecorder.AudioSource#DEFAULT is used. <br>If the audio format is not specified or is incomplete, its channel configuration will be AudioFormat#CHANNEL_IN_MONO, and the encoding will be AudioFormat#ENCODING_PCM_16BIT. The sample rate will depend on the device actually selected for capture and can be queried with #getSampleRate() method. <br>If the buffer size is not specified with #setBufferSizeInBytes(int), the minimum buffer size for the source is used.
