Gammachirp auditory TF representation of gravitational-wave signal GW150914

Authors: Serrano-Pedraza, I. & Sierra-Vázquez, V. (2022)

 

We have developed two Matlab GUIs to process different gravitational waves using the Gammachirp filter (Irino & Patterson, 2001). (Download Matlab programs).

- (Gammachirp_demo.m) This program computes the spectrogram.

-(Gammachirp_Basilar_membrane.m) This program simulates the vibration of the Basilar Membrane. 

 

To run the programs: you have to download the .zip file and unzip the file in a single directory.

Then open and run the script Gammachirp_demo.m to compute the spectrogram or the script Gammachirp_Basilar_membrane.m to simulate the basilar membrane motion.

Last version tested Matlab R2021a. Minimum resolution 1366 x 768 pixels.
