Hello List, I'm trying to find a library or code-snippet in order to do audio resampling from 8khz to 44,1khz and from 44,1khz to 8khz. I need to resample the data in realtime - resampling a buffer of data, not a soundfile. The quality doesn't need to be good so I guess the best solution might be linear audio resampling. The device to do the resampling on is an ARM CM-X255 running at 400MHz.
I tried out libsamplerate so far but when I tested it with the soundfile conversion test program it needed 3,5 secs to sample from 8kHz to 44,1 khz for a 1,7 secs audiofile - which is too slow for me. Is there something faster that can do the job? Any suggestions are highly welcome Greetings, Tobias
