...s of “int” type. Is this type signed 32bit integer? - Do you have some test data, how the echo cancellation algorithm should behave? It will be perfect if we can use it to debug the behavior of all algorithm blocks separately? - In my project I use the onboard ADC to take samples from the MIC every 125uS (8KHz sampling rate) and PWM to output data to the speaker every 125uS. When I collect full frame from the Microphone, I pass trough the EC algorithm. Due to I need the speaker data of the same period, do I need to get earlier speaker data (for example 20-30 samples before the frame period in order...

Hi all, I need a periodic timer running at ideally at 125 microseconds and at least 500 microseconds. I''ve just found the VCPUOP_set_periodic_timer, however there is a comment saying "periods less than one millisecond may not be supported". I will be running on an x64 machine. Is this supported? If not, is there any alternate means of generating a fast interrupt? Regards.
