[Matplotlib-users] audio editor

[Michael M. <mic...@gm...>]

I'm new to Matplotlib and not sure if it's right for my application.

I would like to build a simple audio (sound file) editor with the use of 
Matplotlib. It will plot a waveform, hence the usefulness of matplotlib. 
I will also need the user to be able to select regions of the waveform 
by dragging the mouse or perhaps by clicking at the start and end. I 
want the regions to be highlighted.

I also need a playback cursor.. a line that travels along the waveform 
as it gets played back.

So is there a way to add to Matplotlib custom responses to drags and 
clicks? Something like an animated playback cursor (moving line)? Can 
these be based on natural features of Matplotlib or would I have to hack it?

Thanks,
Mike
