【SPEEX】 use speex resample make noise
Look, how about you start from the testresample.c file? Oh, and you seem
to be reading 320 samples at a time and processing 640, so that can't be
good (and even beyond that your code is wrong for other reasons).

【SPEEX】 use speex resample make noise
Be aware that inlen is an in/out parameter. It tells you how many
samples the resampler read. That number can be smaller than what you
passed -- in which case it means you need to buffer them and give them
to the resampler again in the next call.
