Dimensionality Error with Room Simulation

[arilato]

Following the example code for room simulation found on the docs [https://pyroomacoustics.readthedocs.io/en/pypi-release/pyroomacoustics.room.html], I am running into a syntax error.

My code block:

room = pra.ShoeBox([9, 7.5, 3.5], fs=fs, absorption=0.35, max_order=17)

my_source = pra.SoundSource([2.5, 3.73, 1.76], signal=signal, delay=1.3)

# place the source in the room
room.add_source([2.5, 3.73, 1.76], signal)

R = np.c_[
    [6.3, 4.87, 1.2],  # mic 1
    [6.3, 4.93, 1.2],  # mic 2
    ]

# the fs of the microphones is the same as the room
mic_array = pra.MicrophoneArray(R, room.fs)

# finally place the array in the room
room.add_microphone_array(mic_array)

room.compute_rir()

room.simulate()

Note that fs and signal was already loaded. I am getting an error with FFT:

    375     elif in1.size == 0 or in2.size == 0:  # empty arrays
    376         return array([])

ValueError: in1 and in2 should have the same dimensionality

It seems there's a problem with the dimensionality of signal. They should be 1D ndarrays. Have you checked this is the case ?

[arilato]

I see, I mistakenly assumed a single channel for the audio signal. After ensuring that, I no longer get this error. Resolved!

I am new here in python, have some basic level, I faced same problem in my experiment can you provide the solution with help of code. It seems veryhelpful for me to learn pyton and solved this kind of problem in future.
