How to jump to position in a song? #6

Closed AmyXS closed 3 years ago

AmyXS commented 7 years ago

Hi,

I couldn't find a method that allows for setting the playhead position, wonder if this is supported? I noticed the demo app has a slider that allows for jumping to a different position, could you please explain how this is done?

Cheers!

Hi @swan488, I don't think jumping position is really the job of RubberBand.

You pass in blocks of samples to RubberBandStretcher::process() and retrieve them (stretched) from RubberBandStretcher::retrieve(). So if your input block "jumps" with respect to some larger buffer of audio, then the output from RubberBand will reflect that.

That makes sense, thanks for answering!
