[CELT-dev] listening experiment

Sorry, we have not yet performed listening tests on stereo files. In fact, we've
been working on a new stereo coupling algorithm in the exp_stereo branch and
we'd be interested in feedback on that work before we replace the current
algorithm with it. Any specific application for which you're interested in CELT
spatial information preservation? Note that the stereo coupling is
non-parametric, so as the bit-rate increases, no spatial information should be
lost.

Cheers,

   Jean-Marc
