Minor tuning

9743bf38 – Gregory Maxwell <greg@xiph.org> authored and Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> committed on 2010/11/04 16:45

Switch iteration over channels to the do{}while(); construct in order to inform the compiler that the these loops execute at least once. (This results in more intelligent output from the clang static analysis tool and should also produce faster code on at least some architectures.)

60c316b4 – Gregory Maxwell <greg@xiph.org> authored and Jean-Marc Valin <jean-marc.valin@usherbrooke.ca> committed on 2010/11/04 16:14

Eliminate some promotions to double. A fair number of implicit promotions remain but they all involve math functions which exist only as double precision form in C89.

Fix crashes with VBR for short duration frames and very low bitrates. This may, however, cause the encoder to violate the rate target at insanely low rates.

a9411472 – Gregory Maxwell <greg@xiph.org> authored and Jean-Marc Valin <jean-marc.valin@octasic.com> committed on 2010/10/27 23:52

Switch example tools to use VBR and 960 sample frames by default on the basis that if the user doesn't have any particular requirements that they probably want this.

Further simplications to compute_mdcts()

allocation trim doesn't make sense for stereo after all

c5792dee – Jean-Marc Valin <jean-marc.valin@octasic.com> authored on 2010/10/19 10:24

First shot at automatically adjusting the "allocation trim" for stereo.
