Hi Guys, I'm looking for the optimum audio format when using streamfile in a lua script. I've found CPU load increases rapidly with the number of threads playing a .wav file. Can anyone tell me the optimum when using g711a? Right now the the .wav files are Audio format: PCM Sample rate : 8 kHz Mono Sample Size: 16 bit Bit rate :128kbps Will it help CPU load if I resample to a bit rate of 64kbps and sample size of 8 bit? I have read that the sample size needs to be 13-14bit +1 for alaw/ulaw though Regards,
