Hi, I have a simple speaker output/microphone input system on ADSP-21489, and I'd like to measure the impulse response between them.
It seems that the most straightforward approach is to use the "measurement" block in the library. However, I have some trouble getting the impulse response out of it.
It seems that the output pin should be connected to the speaker output, and the input pin on the "measurement" block should be connected with the microphone readings. Once I toggled the trigger, I could hear the speaker playing the pre-determined noise, but I can't find a place where I can get neither the raw reading nor the estimated impulse response in the block.
Can you please work with me to figure out how I can get the readings out of that block?
Also, if this is not the right module for the job, can you please work with me to figure out the best way to measure the impulse response (recording the raw data and post-process it, or running LMS )?
