I did a deconvolution between two signals, a sweep and an impulse response (actually an impulse response with a very simplified response, I lowpass filtered its magnitude bins in the frequency domain to make it smooth) and as a result, i get what I expect, plus a weird peak (actually two very close peaks) in the frequency domain. In the magnitude, as everything goes smoothly between nearly 0.0 and 0.31, the peaks go up to 105.2 and 19.8, and I have no idea why they are there. Basically everything is normal, the magnitude of the result looks like the impulse response's magnitude kinda upside down, but there as those two peaks, and I have no idea where they're coming from. Does it mean my deconvolution function might be broken? It's just a fast convolution function that was proved to work right except that instead of performing a complex multiplication it performs a complex division
