Reproduced. I'm not sure it is a problem though. A single source might be intentional.

It is intentional design. Two channel sound would result in two distance measurements from two speakers to one microphone. By using only one speaker, only one path is tested.

The relevant code in arange.py contains:

def write_wav(o):
    """
    Writes a [0,1]-scaled array o into the left channel of a 8-bit stereo
    wav-file at 48KHz
    """

Do not design a test for right loudspeaker output in Distance activity.
