Hi Yang,
Just want to make sure I understand one thing correctly: using rational resampler can be slower than mmse resampler given the same 1/n resampling ratio, however it can lead to a signal with better spectrum?it's usually even faster, but you can't use a rational resampler for non-rational resampling. But as long as your resampling ratios are fixed and all rational (which both 1/64 and 1/67.5=2/135 are), I'd recommend using the rational resampler.
