https://community.intel.com/t5/Intel-Integrated-Performance/Problem-of-AEC-Sample-Rate/m-p/978343#M21162 Hello, i tried the AEC example recently. It works well both in the room sim mode and realtime processing in 8k sample rate. But when i change the sample rate to 11k, 16k and 22k, it only works well in the room sim mode, realtime processing result was unacceptable. I have tried to change the define of SAMPLE_RATE(to 11k, 16k and 22k), FRAME_SAMPLES(to 256 and 512), MAX_BLOCK_SIZE(to 256 and 512), FFT_ORDER(to 8 and 9), but it did not work. I also tried define some DELAY_SAMPLES, and it's useless either. Is this AEC sample only support 8k sample rate? or there is still something i should change? Thanks!
