From aebf07075f4244caf591a3af71e5872fe314e87b Mon Sep 17 00:00:00 2001 From: Alexandra Hájková Date: Thu, 17 Dec 2015 15:52:47 +0100 Subject: dca: change the core to work with integer coefficients. The DCA core decoder converts integer coefficients read from the bitstream to floats just after reading them (along with dequantization). All the other steps of the audio reconstruction are done with floats which makes the output for the DTS lossless extension (XLL) actually lossy. This patch changes the DCA core to work with integer coefficients until QMF. At this point the integer coefficients are converted to floats. The coefficients for the LFE channel (lfe_data) are not touched. This is the first step for the really lossless XLL decoding. --- tests/fate/audio.mak | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'tests') diff --git a/tests/fate/audio.mak b/tests/fate/audio.mak index bc107c5017..cf11e9d3c3 100644 --- a/tests/fate/audio.mak +++ b/tests/fate/audio.mak @@ -24,7 +24,7 @@ fate-dca-core: REF = $(SAMPLES)/dts/dts.pcm FATE_DCA-$(CONFIG_DTS_DEMUXER) += fate-dca-xll fate-dca-xll: CMD = pcm -disable_xll 0 -i $(TARGET_SAMPLES)/dts/master_audio_7.1_24bit.dts fate-dca-xll: CMP = oneoff -fate-dca-xll: REF = $(SAMPLES)/dts/master_audio_7.1_24bit.pcm +fate-dca-xll: REF = $(SAMPLES)/dts/master_audio_7.1_24bit_2.pcm FATE_SAMPLES_AVCONV-$(CONFIG_DCA_DECODER) += $(FATE_DCA-yes) fate-dca: $(FATE_DCA-yes) -- cgit v1.2.3
