Acoustic Room Impulse Response (RIR) generator using the (Randomized) Image Method for rectangular rooms. Convolving a RIR with an audio file adds reverberation.
To install the package, hit ] from the Julia command line to enter the package manager, then
pkg> add ImageMethodReverbSee the demo folder for some examples.
Type ?rim for more details. By default the randomized image method from [1] is used. The original image method proposed in [2] can be reproduced as well by turning off the randomization and fractional delays.
A MATLAB implementation of the Randomized Image Method can be found here.
