Android AudioRecord Supported Sampling Rates

Question

I\'m trying to figure out what sampling rates are supported for phones running Android 2.2 and greater. We\'d like to sample at a rate lower than 44.1kHz and not have to re

Answer 1

Android has AudioManager.getProperty() function to acquire minimum buffer size and get the preferred sample rate for audio record and playback. But yes of course, AudioManager.getProperty() is not available on API level < 17. Here's an example code sample on how to use this API.

// To get preferred buffer size and sampling rate.
AudioManager audioManager = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
String rate = audioManager.getProperty(AudioManager.PROPERTY_OUTPUT_SAMPLE_RATE);
String size = audioManager.getProperty(AudioManager.PROPERTY_OUTPUT_FRAMES_PER_BUFFER);
Log.d("Buffer Size and sample rate", "Size :" + size + " & Rate: " + rate);

Though its a late answer, I thought this might be useful.
