OfflineBufferProcesses, a few utilities to manipulate buffers on the server's non-real-time thread

v.1 by Pierre Alexandre Tremblay (2018)

Description

This is a set of offline buffer processes for SuperCollider (https://supercollider.github.io/) augmenting the Buffer class with new instance methods. This project, especially the first few commits of the repository, can be used to understand how to write such process in C.

How to Install from binaries (SC 3.9 on Mac required)

Download the package and read the text file.

How to build from the source code

These instructions are modified from the amazingly streamlined UGen writing tutorial by snappizz (https://github.com/supercollider/example-plugins)

  1. Download the SuperCollider source
  2. Create build directory
  3. cd to the folder where OfflineBufferProcesses is
  4. create a build directory
  5. cd into it
  6. Set the compiler options and build
  7. set the make parameters by typing cmake -DSC_PATH=PATH_TO_SUPERCOLLIDER_SOURCE -DCMAKE_BUILD_TYPE=Release .. 5. for a MacOS fat binary add -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" - or for a personal copy the option -DCMAKE_CXX_FLAGS=-march=native will optimise as fast as the machine will go, at the cost of compatibility with other hardware.
  8. type make, it should compile.
  9. once it is done, install the Ugen and its Declaration by moving them in the release-packaging/OfflineBufferProcesses/classes and 'release-packaging/OfflineBufferProcesses/plugins' respectively, then move the whole OfflineBufferProcesses folder in your Extensions folder.
  10. for MacOS this is where code signature and notarization has to happen...

Enjoy! Comments, suggestions and bug reports are welcome.
