The physical stream format of my line-in audio hardware is 16 bit signed
int lpcm. The HAL converts this to 32 bit float lpcm. My question:
Does the HAL use the cpu to perform this conversion? I'm writing a very
performance-sensitive application which is trying to get 16 bit unsigned
int samples from the line-in source and I would like to aviod needless
conversions. Is there a way to bypass this conversion and get 16 bit
signed int format from HAL? Is there any reason this shouldn't be done
(the captured samples will never be saved as audio data in my
application so quality is not an issue)?
Thanks,
-Zach
