I’ve encountered a problem with the volume in PsychoPy Builder 1.90.2 sound components. If I set the volume to, say, 0.8 and “constant”, I would expect the same absolute sound volume for each trial in a loop. This works well for frequencies (e.g., 440) and notes (e.g., A). However, if I use a wave file for the sound, the volume seems to be treated as relative - it decreases with each trial (probably 0.8 ^ trialN). This is independent of the
constant/set every repeat/set every frame setting. Is this behavior intended?
I have attached a minimal example demonstrating the problem.
