Justin Ruggles	dc7e07ac1f	Add stereo rematrixing support to the AC-3 encoders. This improves the audio quality significantly for stereo source with both the fixed-point and floating-point AC-3 encoders. Update acodec-ac3_fixed and seek-ac3_rm test references. Originally committed as revision 26271 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	ec44dd5fc2	Change the default dB-per-bit code from 2 to 3. This gives slightly better quality in PEAQ tests. Code 3 gives a dBpb value of 2816 = -132dB (128 psd units = -6dB), which corresponds to 22 bits. Since the exponents have an offset applied, the 16-bit source looks like 24-bit source to the bit allocation routine. So using dBpb code=3 is a closer match to the exponent range. Regression test refs updated for acodec-ac3, lavf-rm, and seek-ac3_rm. Originally committed as revision 26144 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	295ab2af6e	Change FIX15() back to clipping to -32767..32767. This avoids a 16-bit overflow in mdct512() due to a -32768 value in costab. References updated for acodec-ac3, lavf-rm, and seek-ac3_rm tests. Thanks to Måns Rullgård for finding the bug. Originally committed as revision 26071 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Justin Ruggles	8c634b707b	Update the test references for lavf-rm and seek-ac3_rm. The references changed due to r25956. Originally committed as revision 26004 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Måns Rullgård	f729c4aea8	regtest: rename seektest ref files using alphanumeric chars only Originally committed as revision 24345 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	d7096d6fdd	Run seektest on all generated files Originally committed as revision 22158 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
