( buffer size is 0x2274, i.e. 8820. )
( this is an important number: 8820 = 4 * 5 * 441. )
( since it is divisible by 4 we know that the buffer will read )
( an exact number of samples, even with 16-bit stereo. and since )
( it is divisble by 441 we know it will always contain a multiple )
( 10 milliseconds of audio. these assumptions help ensure we don't )
