Classes
struct	rack::dsp::Frame< CHANNELS, T >
	Useful for storing arrays of samples in ring buffers and casting them to float* to be used by interleaved processors, like SampleRateConverter. More...

Namespaces
namespace	rack
	Root namespace for the Rack API.
namespace	rack::dsp
	Digital signal processing routines and classes.
