#9: Joint stereo/channel coding?

Changes (by gmaxwell@…):

  * status:  new => closed
  * resolution:  => worksforme


Comment:

 The requirements document addresses this. Efficient stereo encoding is
 desirable but not required.

 http://tools.ietf.org/id/draft-ietf-codec-requirements-02.txt

 5.5.  Stereo support

    It is highly desirable for the codec to have stereo support.  At a
    minimum, the codec should be able to encode two channels
    independently without causing significant stereo image artefacts.  It
    is also desirable for the codec to take advantage of the inter-
    channel redundancy in stereo audio to reduce the bitrate (for an
    equivalent quality) of stereo audio compared to coding channels
    independently.
