Yes, that looks fine to me ... In case it helps, here is a snippet of what
I do to check a samplerate is going to work:
minBuffer = AudioRecord
.getMinBufferSize(rate, config, encoding);
if (minBuffer != AudioRecord.ERROR_BAD_VALUE
&& minBuffer != AudioRecord.ERROR) {
boolean bGood = true;
try {
audio = new AudioRecord(audioSource, rate, config,
encoding, minBuffer);
int istate = audio.getState();
if (istate != AudioRecord.STATE_INITIALIZED)
bGood = false;
} catch (Exception e) {
bGood = false;
}
audio.release();
audio = null;
if (bGood)
return rate;
