Hi @dmrschmidt, Do you have the ability to zoom in/out the waveform and scroll it?

Hey @ldakhoa,

this is not something that's currently supported natively.

If there is no real-time interaction requirement, and you know the beginning and ending boundaries rather statically, you could slice the audio file beforehand and then just pass that into the waveformview.

I'm assuming you're looking for a real-time dragging supported zoom though, to which the answer for now is just an unfortunate "no, sorry".

Hey, thank you for your answer
