摘要:
An audio foot pedal having an activation arrangement comprising a control button and a stationary part, the control button being secured to the stationary part for relative movement along a travel range, the activation arrangement providing a control signal in response to movement of said control button, the audio foot pedal further comprising at least one signal processing arrangement arranged to execute at least two different functional modes, wherein at least one of said functional modes, in response to said control signal, variably controls a signal processing of audio signals communicated to said at least one signal processing arrangement thereby producing an audio output signal to an audio output, and wherein said control signal also controls switching between said at least two functional modes.
摘要:
The control device (10) of a configurable audiovisual effect comprises: - means for generating at least two optical paths traversed by non-parallel light beams (110a and 110b), comprising at least one optical sensor (115) and at least one emitter (105a or 105b) of at least one light beam, - means for measurement (145) of the speed (150) of an object crossing at least two light beams, as a function of a signal (120) from at least one optical sensor representing the cutting of the optical paths by the object, - means for estimation (125) of the longitudinal position (130) of the trajectory of the object as a function of a signal from at least one optical sensor, representing the cutting of the optical paths of at least two non-parallel light beams by the object and - control means (135) referred to as "positional control means" of a parameter value (140) of an audiovisual effect as a function of the estimated longitudinal position.
