cpp-timbreID

An audio feature extraction library for the JUCE framework.
Porting of some of the objects from the Puredata external wbrent/timbreID [1].
A wrapper for aubio/aubio's onset detector is included.

A earlier version of this library was used for the paper On the challenges of embedded real-time audio classification which was submitted to the 25th International Conference on Digital Audio Effects (DAFx20in22). The code for the timbre classifier mentioned in the article is in /master/Demos/Demo-guitarTimbreClassifier
Check the JUCE projects in Demos/ to understand how to use the library.

At an early stage of development, the library was used for the following scientific papers:

Build and usage

At the current stage, library source files (in src/) need to be compiled alongside the user's project. However, most of the code is header-only, requiring to add include to the include path of the project.
The library also includes a convenient wrapper for Aubio Onset, which requires to compile the library in libs/audio. To do so, run the script libs/build_dependencies.sh, which build a tested version of Aubio for both amd64 and Elk Audio OS arm64/aarch64.
