The Orinj Echo is an effect that takes an input signal and repeats it several times. Each
successive repetition is delayed and decayed – it comes later than the previous one and with
smaller amplitude. In this echo, the delay between each two successive repetitions is the
same. The decay between each two successive repetitions is also the same.
The Orinj Echo is very similar to the Orinj Delay, but allows multiple
repetitions of the signal. The Orinj Delay creates only one repetition of the signal.
In essence, the Orinj Echo is a delay with feedback.
Using the Orinj Echo
The Orinj Echo can be added to tracks in the
multitrack session view,
tracks in the
loop building view, and to
waves in the
single wave view. In the multitrack session view and in the
loop building view, first
select the track to which you want to add the effect. In all of these views, click on Effect,
Delay, and then on Orinj Echo in the Orinj menu. You will see
the following dialog.

When this dialog becomes visible, the Orinj Echo effect has been added to the track that
you selected. Adjust the parameters of the echo, which are described below, in the dialog
above and click Close.
Orinj Echo parameters
See Effects for an explanation of the Title, Track, Presets,
Bypass, and Lock channels controls. The remaining Orinj Echo controls are described below:
-
Left channel delay: Use these controls – the box and the slider – to set the delay
between the original signal and the first repetition of the echo signal in the left
channel. The same amount will be used as the delay between the first and second
repetition of the echo signal, between the second and third repetition of the echo
signal, and so on. The delay amount is specified in milliseconds (ms) and can be
between 0 ms and 1000 ms (1 second).
-
Left channel decay: Use these controls – the box and the slider – to set the decay of
the echo. The decay is the amplitude of the first repetition as percent of the amplitude
of the original signal. The same decay will be used as the ratio of the amplitudes of
the second and first repetition of the echo signal, the ratio of the amplitudes of the
third and second repetition of the echo signal, and so on. The decay is between 0% and
100%, where 100% means no decay (the first and every other repetition of the echo signal
is of the same amplitude as the original signal) and 0% means complete decay (the
amplitude of the first and every other repetition of the echo signal is zero).
-
Left channel invert: Click on this checkbox to invert the phase of the echo signal in
the left channel (to turn the signal upside down). Inverting the phase is said to
produce interesting effects with certain other settings.
-
Right channel delay: Use these controls – the box and the slider – to set the delay
between the original signal and the first repetition of the echo signal (and between
each two successive repetitions of the echo) in the right channel. These controls work
in the same way as the left channel delay controls, but on the right channel.
-
Right channel decay: Use these controls – the box and the slider – to set the decay of
the echo signal in the right channel. These controls work in the same way as the left
channel decay controls, but on the right channel.
-
Right channel invert: Click on this checkbox to invert the phase of the echo signal in
the right channel.
-
Max repetitions: Use this spinner to set the maximum number of repetitions that the echo
should have. In theory, the amplitude of each repetition of the echo is smaller, but is
a constant multiple of the amplitude of the previous repetition. This means that it will
never become zero. In practice, the amplitude of the repetitions will become zero at
some point, as PCM wave data can use only a finite number of values to represent the
value of the signal. Nevertheless, this control is here so that you can limit the number
of echo repetitions that that show up in your signal so that the echo is not overly long.
The maximum repetitions can be between 1 and 50.
See Effects for additional notes on: where Orinj effects can be
used, using boxes and sliders that impact the same parameter (such as the box and slider
for the left channel delay), applying effects to mono and stereo waves, and using effects
during playback. The parameters for the left and right channels are separate, as a number
of interesting effects can be created if the echo in the two channels differs (e.g., you
can bounce the echo from one channel to the other).
See Working with effects for additional information on
creating, modifying, moving, removing, and processing effects.
Dry and wet mix
The Orinj Echo supports dry and wet mix changes. That is, you can adjust the mix between the
original signal and the echo. See Effects for more information.
