This is a python compilation of the RIR-Generator code from https://github.com/ehabets/RIR-Generator

Cython is used to compile the code.

Code is taken from the Version: 2.1.20141124 of RIR-Generator.

This package contains: - C implementation of the RIR code and the corresponding .h file - A .pyx fil,e which is a wrapper code written in Cython - A setup.py file to compile the new module

Python dependencies: cython

Compilation: python setup.py build_ext --inplace

-- The system object file rirgenerator.so generated after successful compilation is equivalent to the .mexa64 generated for MATLAB version.

Use case: import rirgenerator as RG

h = RG.rir_generator(c, fs, r, s, L, beta=beta, nsample=n, mtype=mtype, order=order, dim=dim, orientation=orientation, hp_filter=hp_filter)

Input parameters: c : sound velocity in m/s. fs : sampling frequency in Hz. r : M x 3 array specifying the (x,y,z) coordinates of the receiver(s) in m. s : 1 x 3 vector specifying the (x,y,z) coordinates of the source in m. L : 1 x 3 vector specifying the room dimensions (x,y,z) in m. ------ Parameters below needs to be specified as: key=value ---------ex: beta=0.4,nsample=4096,mtype='omnidirectional',order=-1,dim=3,orientation=0,hp_filter=1 beta : 1 x 6 vector specifying the reflection coefficients [beta_x1 beta_x2 beta_y1 beta_y2 beta_z1 beta_z2] or beta = reverberation time (T_60) in seconds. nsample : number of samples to calculate, default is T_60*fs. mtype : [omnidirectional, subcardioid, cardioid, hypercardioid,bidirectional], default is omnidirectional. order : reflection order, default is -1, i.e. maximum order. dim : room dimension (2 or 3), default is 3. orientation : direction in which the microphones are pointed, specified using azimuth and elevation angles (in radians), default is [0 0]. hp_filter : use '0' to disable high-pass filter, the high-pass filter is enabled by default.
