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,
