Horizontal zoom #33

Open ali-fairbrass opened 10 years ago

ali-fairbrass commented 10 years ago

Would it be possible to add a horizontal zoom function similar to the vertical zoom function?

Did you decide to change the time dimensions of the spectrogram to do this? Can I help in any way?

Had no time to do this, but I will incorporate it now. Hope to have it done tonight.

I implemented now two fixed spectrogram parameters, one for audible range and one for ultra-sonic range. The ultra sonic range shows the typical hockey shapes on bat calls.

I chose these two modes because they take the same time to compute. The ultrasonic mode is 10x less resolution in frequency, but 10x higher resolution in time.

If these modes are not convenient there is no reason why we have to stick to them. Everything is ready to use any resolution in time and frequency range.

PLEASE BE CAREFUL. AS LONG AS #37 IS NOT CLOSED, THE PROGRAM DOES NOT SAVE WHICH MODE THE ANNOTATION WAS DONE IN. I.E. ALL POST PROCESSING WILL HAVE TO ASSUME THAT THE LABELLING WAS DONE IN THE AUDIBLE MODE, WHICH WILL LEAD TO ERRORS.

ONLY USE TO TEST THE FUNCTIONALITY.

It looks really good. Both visually and acoustically this makes labeling the ultrasonic files much easier.

How would you like to proceed? Should we make a decision about how the mode data should be appended to the label data?
