Audio Analysis & Onset Detection
Onset Input:
The
Onset Input
is an AC coupled audio input for the audio
analysis section of
arbhar
.
•
The
Onset Input
is normalised to the
Input
.
•
Depending on the currently selected mode, signals present at the
Onset Input
will activate capture. This is the default functionality.
Onset Indicator:
The
Onset Indicator
shows when onset detection
is armed. If the indicator is illuminated, onset detection is armed. If
the indicator is unilluminated, an onset was detected and will remain
unarmed for the duration of time set by the
Hold
parameter. The
Onset
Indicator
relates to the
Onset Control Modes
and is dependent on the
Sensitivity
and
Hold
parameters.
•
In the alpha and beta
Onset Control Modes
, the
Onset Indicator
illuminates amber to show that a detected onset will activate capture.
•
In the gamma and delta
Onset Control Modes
, the
Onset Indicator
illuminates white to show that the detected onset will generate gate
signals at the
Gate Output
.
•
Once an onset is detected, the
Onset Indicator
will be unilluminated
for the duration of time set by the
Hold
parameter.
•
When the
Onset Indicator
illuminates again,
arbhar
is waiting for
another onset to detect.
•
In the gamma
Onset Control mode
, onset-derived gate signals
will be mixed with the gate signals generated by the
Continuous
Granular Engine
.
•
In the delta
Onset Control Mode
, the onset-derived gate signals are
solely dependent on the detected onset.
•
In the delta
Onset Control Mode
, it can be useful to connect the
Gate Output
to the
Capture Gate Input
, and set the
Hold
parameter
to have a time duration as long as the capture duration.
Sensitivity:
The
Sensitivity
parameter sets the responsiveness of the
Onset Input
.
