This library provides the c-bindings for the aubio audio library.

Well, you have to have libaubio installed in your computer. You should probably check out the aubio download page It's worth noting that in this part, you could choose to install other libraries (such as libsndfile or FFTW) and build aubio with them so it will try to leverage some of the work to those libraries. It is totallly optional.

This project exposes two packages (each one in its own system):

This is the one that you should use. It contains all the lipsy translations and utility wrappers for the actual c functions/structures.

This package contains the raw bindings, with no name processing or whatsoever. You should only use this package if I was super lazy and didn't provide a lispy binding for some function.

A package to contain all the examples of usage of the different aubio objects

Before explaining each object by itself, I want to tell you that the guys and gals in charge of the aubio project did an extremely good job at mantaining its API object oriented. And what I am refering to is that

• every object can be created with new_aubio_<name-of-the-object>
• and can be destroyed with del_aubio_<name-of-the-object>
• and most of them have a aubio_<name-of-the-object>_do (which seems to respond of a method object of sorts)

So, in my Lisp translation I'm trying to mantain that convention in this form:

• every object will be created with a make-<name-of-the-object> function
• every object will be deleted with a clean generic function
• I'll try to make a generic function for the do part, but only if I find that it makes sense to have a polymorphic way of dealing with some objects. In other cases, I probably will generate functions with more descriptive names of what the object is actually doing

Important note: In order to distinguish the object that represents the detection algorithm and the thing being detected in this Lispy translation there exists two different objects to reify those two thing (like the note-detector and the note itself). In the aubio source, there is no "detector" and the detector is named after the thing it detects. There is no struct or datatype that reifies the thing being detected (in the previous example, a note is simply a list of three elements)

• Source
• Sink
• Pitch detection
• Onset detection
• Note detection
• Tempo detection
• Filterbank
• Aubio data structures
