I'm designing a simple active noise control experiment using the ADI ADAU1467 as the processor. Before designing the ANC system, I need to measure/characterize the transfer function from the speaker to the microphone. On the MFxLMS block, there is a secondary path training tab that seems to do exactly this. But I don't see a way to export the FIR coefficients afterwards. Ideally, I'd like to obtain time-aligned time series data for the input (speaker) and output (mic) signals so that I can apply my own system ID tools. Is this sort of thing possible with the ADAU1467? Or will it be necessary to acquire alternative signal generation/DAQ H/W to measure the response?
