You already know that this code is based on Stephan M. Bernsee "smbPitchShift.cpp" v1.2.
From my point of view, I don’t know any other code providing a so fast pitch-tracker, here embedded in a pitch-shifter.
On a fast machine (G5 dual or Quad, Mac Pro), it can be used for real-time processing (latency < 10 milliseconds) when playing a musical instrument such an electric guitar or an electric violin.
Tested on a G5 Quad 2*2.5gHz.
All known bugs have been fixed and successfully recompiled in Xcode 2.4.
Well, is it worth looking at this code to translate part of it into a MaxMSP external, or not?
I have the free time for, but for what result in MaxMSP?
Could I expect a same performance as an MSP external versus a ‘pure’ AU plug-in?
In advance, thanks for your insights.
The #include are:
- in the cpp, the following header:
- and in "Pitchy.h":
vDSP_create and vDSP_destroy are (See vDSP.h in Xcode):
* Mac OS X: in version 10.2 and later in
* CarbonLib: not available
* Non-Carbon CFM: not available
