Cuki-IR-generator is a Software to generate IR files from acoustic instruments. This version works on GNU Octave and needs no packages. So it is very easy to use.
I started to develop this program years ago. This is a "light" version of the program I initially created using MATLAB.
Acoustic guitar IR generator "light" 1.0 Author: Kien Phan Huy on the 14th of July 2020. Copyright 2020
All you need is:
- A computer (Mac, PC)
- A 2-channel audio interface
- A microphone
- An acoustic guitar with an onboard pickup
- 2 cables (one for the mic, one for the guitar)
- GNU Octave GNU Octave installed on your computer.
- Download and install GNU Octave
- Download Cuki-IR-generator official realease from http://acousticir.free.fr or clone this repository.
- Run GNU Octave and make sure to choose the working directory where you saved the IR generator program
- Open the script Cuki_IR_gen1r.m and run it.
- Follow the steps on the youtube video
-
Linux Users: The save button is not visible by default, so you need to activated by replacing all occurrences of
ispcwithispc|isunix(Check: #1). -
A wav file containing a previous audio recording, with DI on left channel an MIC on right channel, can be use but the button must be enable by uncommenting line 231 of the script (Check: #2).
