    1. Channel damp (0dB / mute)
    This mode will not compensate for power loss at all. If a signal is panned hard left or right, the
    the sum of the channels will drop by 3dB.

    2. Constant power (+3dB / mute)

    This is the default mode. Regardless of the pan position, the power of the sum of the channels
    remain constant.

    3. Channel boost (+4.5dB / mute)
    If this mode is selected and a signal is panned hard left or right, the power of the sum of the channels
    will actually be higher than with a signal panned center.

    4. Channel boost (+6dB / mute)
    This is the same as the previous option, but with even greater power boost.

    Best regards

    Maybe I'm not following you, but I'm not really sure how you would do that. I'm talking about playing back one unique file with two different applications, and not a comparison between two separate files.

    Thanks for passing that along, Andreas. I did see that section in the Wavelab operations manual, but my understanding is those modes are specifically in play when using pan envelopes. For comparative playback, I simply want to open a stereo .wav file and hit 'play'.

    OK...I just saw it. Must have looked right at it before, but didn't see it ...mode #2 is the default mode, which I'm going to assume is the active mode when no pan envelopes are used.
    So, if that's the case, then it may well account for at least some of the differences in playback, since my understanding of the default for the other application (Sonar Producer) is 0dB.

    Here are the Sonar Panning Laws:

    #1
    (Default) 0 dB center, sin/cos taper, constant power

    This choice causes a 3 dB boost in a signal that’s panned hard left or right, and
    no dip in output level in either channel when the signal is center panned.

    #2
    -3dB center, sin/cos taper, constant power

    This choice causes no boost in a signal that’s panned hard left or right, and 3dB dip in
    output level in either channel when the signal is center panned.

    #3
    0dB center, square-root taper, constant power

    This choice causes a 3 dB boost in a signal that’s panned hard left or right, and no dip
    in output level in either channel when the signal is center panned.

    #4
    -3dB center, square root taper, constant power

    This choice causes no boost in a signal that’s panned hard left or right, and 3dB
    dip in output level in either channel when the signal is center panned.

    #5
    -6dB center, linear taper

    This choice causes no boost in a signal that’s panned hard left or right, and 6dB dip in output level in either
    channel when the signal is center panned.

    #6
    0 dB center, balance control

    This choice causes no boost in a signal that’s panned hard left or right, and no dip in output level in
    either channel when the signal is center panned.


    I also found this table. Maybe it is of some help.

    Andreas,
    That is some excellent information you found about Sonar, and I sure appreciate you posting it !

    Very useful reference material.

    Thanks very much.
