Detailed Description

template<unsigned int NUM_BUFFER_SAMPLES, class T = int>
class ControlDelay< NUM_BUFFER_SAMPLES, T >

Control-rate delay line for delaying control signals.

For example, this could be used to produce echo-like effects using multiple instances of the same voice, when AudioDelay would be too short for an actual audio echo. This is in fact just a wrapper of the AudioDelay code.

Template Parameters

NUM_BUFFER_SAMPLES	is the length of the delay buffer in samples. This should be a power of two.
the	type of numbers to use for the signal in the delay. The default is int8_t, but int could be useful when adding manual feedback. When using int, the input should be limited to 15 bits width, ie. -16384 to 16383.

Member Function Documentation

next() [1/2]

template<unsigned int NUM_BUFFER_SAMPLES, class T = int8_t>

T AudioDelay< NUM_BUFFER_SAMPLES, T >::next ( T  in_value, unsigned int  delaytime_cells  )

inlineinherited

Input a value to the delay and retrieve the signal in the delay line at the position delaytime_cells.

Parameters

in_value	the signal input.
delaytime_cells	sets the delay time in terms of cells in the delay buffer.

Definition at line 59 of file AudioDelay.h.

next() [2/2]

template<unsigned int NUM_BUFFER_SAMPLES, class T = int8_t>

T AudioDelay< NUM_BUFFER_SAMPLES, T >::next ( T  in_value )

inlineinherited

Input a value to the delay and retrieve the signal in the delay line at the position delaytime_cells.

Parameters

in_value

the signal input.

Definition at line 77 of file AudioDelay.h.

read()

template<unsigned int NUM_BUFFER_SAMPLES, class T = int8_t>

T AudioDelay< NUM_BUFFER_SAMPLES, T >::read ( unsigned int  delaytime_cells )

inlineinherited

Retrieve the signal in the delay line at the position delaytime_cells.

It doesn't change the stored internal value of _delaytime_cells.

Parameters

delaytime_cells

indicates the delay time in terms of cells in the delay buffer.

Definition at line 104 of file AudioDelay.h.

set()

template<unsigned int NUM_BUFFER_SAMPLES, class T = int8_t>

void AudioDelay< NUM_BUFFER_SAMPLES, T >::set ( unsigned int  delaytime_cells )

inlineinherited

Set the delay time, measured in cells.

Parameters

delaytime_cells

how many cells to delay the input signal by.
