This is a gain applied to the input right before it is written to the
underlying file. The only effect is on the gain of the resulting file,
whereas the gain of any real-time/ugen graph signals are unaffected.

Manual closing of the file is still supported, this current bug
notwithstanding. The latest release introduced the issue, basically
WvOut's destructor and closeFile() both try to close the file and
interfere with each other. This will be fixed in the upcoming bugfix
release.
