Usage (Python API)

The package can be included in a Python script as simple as:

from irdl import get_fabian

data = get_fabian(kind='measured', hato=10)
print(data)

{'impulse_response': time domain energy Signal:
(11950, 2) channels with 256 samples @ 44100.0 Hz sampling rate and none FFT normalization
,
 'receiver_coordinates': 2D Coordinates object with 2 points of cshape (2, 1)

Does not contain sampling weights,
 'source_coordinates': 1D Coordinates object with 11950 points of cshape (11950,)

Does not contain sampling weights}

Usage (CLI)

Once installed, the package provides a convenient command line script which can be invoked with irdl.

$ irdl --help
