Re: resend: Re: [ecasound] Re: Resampling in realtime (fwd)

Last night, I ran a quick test of 44100 -> 96000 with 16-bit samples.
Results are good. No clicking. Max difference 1 LSB. I'll post more
complete results within a couple of days.

See http://www.ai.sri.com/ajh/audio/resamp-test-4

for the files. The main file of interest is:
