(The only real solution would be switching to "RF64" as the common intermediate format. But as long as most of the audio tools don't support RF64, this is a lost case)
And it looks like this is not gonna happen anytime soon.

I found a request for SoX to support RF64 plus the answer from Chris Bagwell (it is from 2006), and it does not sound encouraging:

Re: New file format? (RF64)
It would be nice to at least see the WAVE64 portion to be rolled into
the current WAV handler. I've seen several requests for > 4gig audio
files in WAV format.

It should be simple enough to add support for both WAVE64 and RF64 since
the code to parse chunks already exists in the wav.c. Just need to
tweak it some to work with these other formats. I'll have to leave that
as an exercise for someone else though.

Which brings us back to the hard sad facts:

Unless LameXP changes its design fundamentally, it does (and will) not support multichannel source files with a duration of more than 2 hours.

For a 6-ch AC3 source file (16bits, 48 kHz) the threshold is at 2 hours 4 minutes. Audio files which are longer than this are quite common these days. This really limits the usefulness of LameXP.
