VariableSpeedRingBufferSimple< T > Class Template Reference

Very Simple Buffer implementation for Pitch Shift. We write in constant speed, but reading can be done in a variable speed. We will hear some noise when the buffer read and write pointers overrun each other. More...

virtual T *	address ()
	returns the address of the start of the physical read buffer
virtual int	available ()
	provides the number of entries that are available to read
virtual int	availableForWrite ()
	provides the number of entries that are available to write

Detailed Description

template<typename T>
class audio_tools::VariableSpeedRingBufferSimple< T >

Very Simple Buffer implementation for Pitch Shift. We write in constant speed, but reading can be done in a variable speed. We will hear some noise when the buffer read and write pointers overrun each other.
