	SRDelay (float timeMs)

Patchable &	set (float timeMs)
	sets the default delay time value and returns the unit ready to be patched. More...

Patchable &	in_signal ()
	Sets "signal" as selected input and returns this Unit ready to be patched. This is the default input. This is the signal to be delayed. You can patch the output back to this input to make a feedback path.

Patchable &	in_time ()
	Sets "time" as selected input and returns this Unit ready to be patched. This is the delay time and obviously support audio-rate modulation. The time value is clamped to the max delay time of the delay buffer and to the minimum by the audio buffer size time.

Patchable &	out_signal ()
	Sets "signal" as selected output and returns this Unit ready to be patched. This is the default output. This is the delayed signal.

void	setMaxTime (float timeMs)
	sets maximum delay time of this delay, The old delay buffer will be deleted and a new will be created, so this is absolutely not thread safe if used in the audio callback. More...

float	meter_time () const
	returns the time value at the start of the last processed buffer. This method is thread-safe.

	disconnects all the inputs and outputs to their connected outputs and inputs. Also resets the selected input and output to the default.

InputNode &	getSelectedInput ()
	returns the selected input, you can patch a Patchable or OutputNode to it with the >> operator.

OutputNode &	getSelectedOutput ()
	returns the selected output, you can patch it to another Patchable or InputNode with the >> operator.

Detailed Description

Send/Return Delay. Digital Delay with patchable feedback path.

SRDelay is a digital delay, the minumim delay time for this delay is dependent on the audio buffer size, keeping this limitation it is possible to send the output of SRDelay into other Unit and then patch it back to the input, creating external processing chains for the feedback path. It is also adviced to use a OnePole high pass filter before the input set at 10-20hz to leak any DC offset. The max time of SRDelay is settable with setMaxTime() or using the SRDelay( float timeMS ) constructor.

Member Function Documentation

◆ set()

pdsp::Patchable & pdsp::SRDelay::set ( float timeMs )

sets the default delay time value and returns the unit ready to be patched.

Parameters

[in] timeMs delay time in milliseconds

◆ setMaxTime()

void pdsp::SRDelay::setMaxTime ( float timeMs )

sets maximum delay time of this delay, The old delay buffer will be deleted and a new will be created, so this is absolutely not thread safe if used in the audio callback.

Parameters

[in] timeMs new maximum delay time.
