Pan Law compatibility modeWhen using a non-default pan law with floating or 24-bit audio, SONAR would previously apply the pan law twice; once at the clip level and once more at the track level.

In SONAR 8.5.2 and later, pan laws are only applied once at the track level and only for mono tracks.  Any clip pan envelopes will continue to work, but behave strictly as a balance control.

If you have existing projects that use a non-default pan law (i.e. other than "0 dB center sin/cos taper"), the mix might sound louder in SONAR 8.5.2.  To address backwards compatibility with projects that were mixed in previous versions of SONAR, the following AUD.ini variable is available to set the pan law compatibility mode:

PanLawCompatMode=<0 or 1> (default=0)

This variable should set in the [Wave] section, for example:

[Wave]
PanLawCompatMode=1

When the value is 0 (default), non-default pan laws are not applied at the clip level.  Clip pan envelopes always use the 0dB center sin/cos taper law.

When the value is 1, pan laws are applied at the clip level.  It is not recommended that you use this value unless you need to retain backwards compatibility with pre-SONAR 8.5.2 projects that use a non-default pan law.
