Detailed Description

A specialized MemoryTemplate for two-channel (stereo) audio.

StereoMemory stores two channels of audio samples and can retrieve past samples for both channels simultaneously using cubic interpolation.

Constructor & Destructor Documentation

vital::StereoMemory::StereoMemory ( int size )

inline

Constructs a stereo memory with the given size.

Parameters

size	The initial size of the memory buffer.

vital::StereoMemory::StereoMemory ( StereoMemory & other )

inline

Copy constructor.

Parameters

other Another StereoMemory to copy from.

force_inline poly_float vital::StereoMemory::get ( poly_float past ) const

inline

Retrieves a poly_float of samples from the stereo memory using cubic interpolation.

Parameters

past	A poly_float of "time ago" values (for one channel pair).
