I'd like to calculate a set of false colour spectrograms, from long-duration audio -- i.e. the type of visualisation introduced by Michael Towsey's research group at QUT, like this:
The QUT Ecoacoustics group have open-sourced their own analysis code which is the "official" implementation. It runs on Windows/Mac/Linux. (But it's implemented using Windows tools (Mono and Powershell) so on my Linux laptop I'd have to install a lot of extra kit to get it running.)
I wrote (together with Sarab Sethi) a Python script to calculate them. (It produced the lower image shown above.) It has the advantage of being a simple standalone Python script, but it's not perfect -- it doesn't implement all the same acoustic indices as the QUT original.
Hence my question: Has this type of long-duration spectrogram been implemented in any other software or scripts?
