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.
