acoustic simulations in Julia

[Niccolo' Antonello]

Dear julia fellow users,

I wanted to tell you that I just released some Julia code for acoustic simulations:
https://github.com/nantonel/JuFdtd
- a finite difference time domain simulator for room acoustics
https://github.com/nantonel/JuRIM
- a image source method room acoustic impulse response generator
there is lot of space for improvement from the computational point (in particular for the FDTD which is currently not parallelized)
so feel free to join their development!

Very cool. The may be more discoverable on GitHub if they follow the standard naming convention for Julia repos – i.e. ending in ".jl" instead of having a "Ju" prefix.

I uploaded this to:
https://github.com/nantonel/RIM.jl
and:
https://github.com/nantonel/Fdtd.jl
thanks for pointing that out!

Note that "FDTD" is a bit too generic ... the term could apply to any time-dependent PDE, and is commonly used for Maxwell's equations.   I would suggest something more specific, like ScalarWaveFDTD

(Wouldn't FDFD, i.e. the frequency-domain scalar Helmholtz equation, be more appropriate for this sort of problem?  Depends on how wide a bandwidth you care about and what you want to simulate, I guess.)

Hi Seven,

yes you are right it's too generic! I will change it to AcFdtd.jl since this stuff was done for room acoustics simulation!

Thanks for pointing that out!

(ps yes frequency domain is not best suited for auralization might be an application for this)
