MISO and MIMO- calculation problem in static IR

[david1412]

how can I get the Static impulse response from multiple sources.

#######################Static impulse respones########################
waveform, shift, _ = fractional_delay(delay, Lf, fs=fs, type='lagrange')
h, , = construct_ir_matrix(waveform * weight[:, np.newaxis], shift, N)
h = h.T

denom = denominator(h, Phi)# denominator of formula

#######################End of Static response######################

this is the code to calculate Static impulse response.

if mic num is two, distance is also two.

then can not calculate the waveform and shift and so on.

Please take a loot at #1.

For multiple source-receiver combinations (in this case, multiple-source and single-receiver), you need the same number (let's say M) of impulse responses. Those have to be computed individually, which mean you will have 'M' set of impulse responses (waveforms and shifts).

Now we have the all impulse responses we need for the simulation. The next step is simulating the microphone signal which captures the sound waves emitted by all sources. The microphone signal is the superposition of the contributions from the individual sources. First, you have to simulate M signals corresponding to the sources using the impulse responses (or the waveform and shift from above). Then, add them up, which is now the captured signal. Keep in mind that the excitation signal differs for each source.
