Alex Converse	ecc1f8c3c8	aacsbr: Make the previous value of bs_num_env local to read_sbr_data(). Originally committed as revision 22409 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	46751a65e3	aacsbr: Initialize e_a[1] to -1. This triggers lAPrev (e_a[0]) on the first SBR frame to be -1. The spec is somewhat ambiguous to what this value should be but this increases the accuracy of al_sbr_e_44_1 and similar streams from 14 bits to 15 bits.
