Description of the problem:
I’m running an experiment looking at temporal estimation in accelerating and decelerating tones. I have everything working except that on my computer in both firefox and chrome (Macbook), sometimes the sound gets randomly distorted (I can only describe it as… buzzy?) at some time point during the files. In addition, some tones can randomly be delayed from their position in the wave file. That’s an important issue for a study on temporal estimation!
I always knew that the start of a sound could be delayed but in this case, each wav file corresponds to one trial (8 tones). So it seems the delay is occuring in the middle of playback.
Question 1. Do other people on other computers also hear this distortion in my experiment? I get it about once every two or three trials.
Question 2: How to fix this? I haven’t seen this problem described in other issues. I’m using 16-bit wav files which both firefox and chrome claim to be compatible with. Should I bite the bullet and switch to mp3?
Thanks in advance for your input!
