Description¶
A simple tone sound stimulus
Signature¶
sound/tone
Required Parameters¶
frequency¶
- Example:
440.0
Frequency of the tone (hertz)
Optional Parameters¶
duration¶
- Default:
0- Example:
2s
Duration of the tone (microseconds). If less than or equal to zero, the tone will continue playing until stopped explicitly with Stop Sound.
ended¶
Variable that will be set to true after the tone finishes playing.
If duration is less than or equal to zero, or if the tone is stopped explicitly with Stop Sound before playback completes, the variable will never be set.
volume¶
- Alias:
amplitude
- Default:
1.0
Controls the volume at which the sound plays. 1.0 is full volume, while 0.0 is silent.
pan¶
- Default:
0.0
Controls the stereo panning of the sound. Acceptable values range from -1.0 (left channel only) to 1.0 (right channel only). A value of 0.0 produces an even balance of the left and right channels.
