Creating very specific filters with Sigma studios

Hello,

I'm working on a project where I have to convolve a signal with an impulse coming from the left or right of a microphone to get a specialisation effect. I would use either an ADAU145x or ADAU 146x for the FFT capabilities.

If I am to work with Sigma Studios, my problem is that I don't know how I would upload the impulse coming from the left/right to the chip with Sigma Studio. My problem comes back to the fact that I don't know how to upload and save outside signals with Sigma Studios. I might be be able to use Look up tables but I really don't know whether that is a viable solution.

If the way I'm phrasing my problem is unclear, I can try to explain it better if needed.

Thank you for your future help.
