Beta 11, how to handle progress, drawer ?

[michelson]

Hi there, We have updated the beta of Wavesurfer, and in the previous version we did some calls to the backend and drawer objects, as they are not present in the current beta version what is the proper way to handle the following calls?

wave.drawer.lastPos
wave.drawer.progress(percent)
wave.backend.getPlayedPercents()

thanks

In v7, you have methods like wavesurfer.getCurrentTime(), wavesurfer.setTime(seconds), wavesurfer.seekTo(percentage).

getPlayedPercents would be wavesurfer.getCurrentTime() / wavesurfer.getDuration().

Thanks! it works

Why does getDuraiton return "auto"? It used to return the length of the wave file...

Here is the code. Here is the wav file dropbox link:

If I changed the initialize to not provide the peakdata, then I get no error...

[doctor30309]

Sorry to be a PIA. Fixed the peak load problem... Works fine...

[doctor30309]

Scratch everything. I have it working except now the waveform does not fit in view and scrolls which I don't want.
