<![CDATA[Pitch Shifting and Time Stretching - Audio Plugin]]>Hi guys,

As we all know we do not yet have pitch shifting or time stretching functionality in HISE but I was wondering whether this would be possible using the HISE C++ framework.

I'm keen to get using the framework if it is possible as there are quite a few open source libraries that do time stretching and pitch shifting that I'd like to play about with and implement.

http://www.surina.net/soundtouch/

Does anybody know that best way to get started with this in HISE.

Cheers,

Lee

Have a look at the project I linked to above, it might point you in the right direction.

@d-healey im clever how to add effects like this to hise?

C++

SoundTouch is horrible, I'd prefer Rubberband, but then there are licensing issues.

Looks like Christoph is considering Rubberband integration at some point:
