Increase volume for Illiminable DS filters?

I have been using the Illiminable DirectShow filters for OGG/FLAC for some time now.
Apart from a small inconvenience it has all worked perfectly!

When playing a playlist with mixed MP3 and FLAC songs I notice that the FLAC songs always seem to played at a much lower volume.
The MP3s have come from different sources and seem to be approx. of the same volume.

Is there some way to alter the output volume of the ogg/flac DS filter?
I'd hate to be forced to use a different filter or even change format, but the difference in output volume is simply too significant to ignore....

OK, the normalize thing does seem to force all audio types to some common volume.
But the first tenth of a second (before normalization I guess) the volume is low and then it is suddenly raised.
This is somewhat annoying, is there any way to get around it?

There was a bug in the last (0.69) and all previous releases of oggcodecs with regards to flac. The amplitude of the waveform was being mistakenly halved, before being written to the audio buffer.

This has since been fixed and will be in the next release, which is not too far away.
