Thas class represents an plan object that allows to calculate FFTs and IFFTs.
Definition: FFTPlan.h:40
#define AUD_API
Used for exporting symbols in the shared library.
Definition: Audaspace.h:93
#define AUD_NAMESPACE_END
Closes the audaspace namespace aud.
Definition: Audaspace.h:119
The main header file of the library defining the namespace and basic data types.
