Author: Derek Buitenhuis <[email protected]> Committer: Anton Khirnov <[email protected]> Date: Thu Feb 23 10:55:35 2012 -0500 wavpack: Don't shift minclip/maxclip Since we are clipping before we shift the values to 16 or 32 bits, we should not shift the min/max clip values to compensate. Fixes 8 and 24 bit lossy decoding.
