AudioCallback Buffer Size

Hi,
I was wondering what the value is for the “size” argument of the AudioCallBack function and what determines this value.

Thanks,

It specifies the number of samples in the audio buffers. It is determined by the setup code that initializes the audio system, take a look at libDaisy/src/daisy_seed.cpp:230-232

Thanks! Just what I was looking for! I see that the buffer size is 48, which, I’m guessing, was done so that the buffer holds exactly 1 ms at a 48kHz sample rate.
