Re: [ARSCLIST] File Size Confusion

[Rob Poretti <r.poretti@xxxxxxxxxx>]

Hi Brandon,

Under certain conditions WaveLab will automatically switch to RIF64 - ex:
making a new recording.  Unfortunately, the current version does not support
this mechanism while converting from a CODEC.  However, the current beta now
has this functionality.  Philippe himself tested it with a 9GB mp3...

The current beta-version is a release candidate for a new patch.  Philippe
will post it with the beta-list in the next day or so, and then it has to be
QA'd... After which it will be released on Steinberg's site as a patch.

I'll let the list know when it is available...

Cheers!
