Change colormap used to display spectrogram to make harmonics more visible #50

Open macaodha opened 10 years ago

macaodha commented 10 years ago

The current colormap makes it hard to see all the detail such as harmonics of a bat call. In the image, the left is the current view and the right is the standard matplotlib imshow colormap. Harmonics are marked with blue boxes. Its hard to see them in the image on the left.

@macaodha Oisin, could you send me that audio file above so that I can play around with the colormap settings please?

groakat commented 10 years ago

In a way, we could place a combobox (like for the audible/ultrasound settings) somewhere where people could select a colourmap they prefer.

Could you send it to me attached to an email?

Github must have eaten it. I just sent it to your UCL mail.

In the ideal case there would be a way to specify the colormap from one of several using a dropdown menu.
