This repository contains auditory and visual stimuli that do not require PsychoPy. The auditory stimuli use the python sounddevice library and the visual stimuli use the python opencv library.
This repository is available for python ≥ 3.8 on pip with the command
pip install stimuli or on conda-forge with the command
conda install -c conda-forge stimuli.
from stimuli.audio import Tone
sound = Tone(volume=80, frequency=1000)
sound.play()
The volume can be set independently for each channel (stereo) by providing a tuple
(L, R).
Visual stimulus can be grouped into 2 categories:
- simple visuals that are drawn on top of each other
- feedback visuals that are drawn once and updated
from stimuli.visuals import Text
visual = Text()
visual.background = "lightgrey" # equivalent to visual.draw_background()
visual.putText("Top secret not-so-secret instructions!")
visual.show()
import numpy as np
from stimuli.visuals import FillingBar
visual = FillingBar()
visual.background = "lightgrey" # equivalent to visual.draw_background()
visual.putBar(length=200, width=20, margin=2, color="black", fill_color="teal")
for k in np.arange(0, 1, 0.1):
visual.fill_perc = k # update the visual
visual.show(100) # wait 100 ms
visual.close()
