I am using AudioConverterConvertBuffer to convert my audio data from 8k,
16-bit, 2-channel, linear to the required 44.1k, float, 2-channel,
linear needed for coreaudio. Unfortunately, I am getting discontinuities
in the output data resulting in clicking sounds.
By sending 44.1k data into the AudioConverterConvertBuffer routine, I
can eliminate the clicking. Passing in 8k, floats still clicks. Thus, I
have determined it is the upsampling that is creating the clicks.
Is there any way of correcting this through coreaudio, or do I need to
come up with my own upsampling routine?
Thanks,
Harry Mahoney
