stimulus/sine_wave Sinewave Properties to describe a sinewave stimulus. Modality string The stimulus modality like acoustic, haptic, light etc. Duration float s The duration of the stimulus in seconds. TemporalOffset float s The temporal offset (with respect to the begin of the recorded trial) with which this stimulus was presented. Function string The function of the described stimulus. E.g. if the white noise constituted the carrier. OutputChannel string The physical output device (e.g. an analog output channel, a monitor screen, the same loudspeaker, etc.). This information can be used to explicitly express that several stimuli (that share the same OutputChannel) are jointly presented. Frequency float Hz The frequency of the sinwave stimulation. Phase float Hz Phase shift of the sinewave. Amplitude float Amplitude of the sinewave modulation. MeanIntensity float The mean intensity of the stimulus. Position 2-tuple The position of the stimulus on e.g the screen. Specified as a 2-tuple (x;y). By default this position refers to the top-left corner of the object or its bounding box. PositionReference top-left string center string bottom-right string By default stimulus positions are specified by the coordinates of the top-left corner (or of the bounding box). Use this property for other definitions. SpatialExtent 2-tuple The spatial extend of the presented stimulus (width;height) e.g. (1024;768).
