Create spectrograms of wav files and save as jpeg

General
1

I am a masters student working with dolphin acoustics. I have very little coding experience and am looking for help with a problem. I have thousands of short (4 sec) wav files of dolphin whistles I would like to save as jpegs to ease analysis.

I was wondering if anyone had code or could produce code in either MATLAB or R to load .wav files from a folder and save each one individually as a jpeg. The fft I am looking for would be 1024. All files are 4 seconds and at 96kHz.

Thanks Jack

The bioacoustics and dynaSpec packages seems to have support for this kind of activity.

Learn more at https://marce10.github.io/. These packages aren't on CRAN, but do appear to be under active development (and cran gives an archived message about bioacoustics when I visit their page, which is confusing to me).
