About implementation
5.1. How does PaceMaker work
Description about the sound processing algorithms used in PaceMaker is to be written. There are some related notes on the SoundTouch README file you might wish to check meanwhile.
(if a long time has elapsed with nothing new here and you're curious, please drop me an e-mail and remind).
5.2. Other algorithms
Overview of other approaches to tempo/pitch scaling is to be written (if a long time has elapsed with nothing new here and you're curious, please drop me an e-mail and remind).
5.3. Source code
PaceMaker v1.3 source codes aren't currently available for public. However, given a good reason I may consider handing them out, e.g. for porting the plug-in to some other player/platform. Source codes for older PaceMaker versions are available here.
Also have a look at the SoundTouch library for similar sound processing routines to be used in own applications.
