DTS-MA,DOLBY D, DTS CORE 1.5 comparison

[saprano]

*mods this has to do with the ps3 and receiver so this can go anyware*

ok so for the past 3 hours iv been comparing these audio codec's cause iv been seeing post on here and avs about how the 1.5 core sounds the same as MA. or the receiver sounds better than the ps3 ect, ect. you know the usual talk on ps3 vs receiver. so i decided to do a little comparison myself and here is what i came up with:

receiver is on 23db and the movie im using is live free die hard

BITSTREAM-dolby digital vs dts core= they both sound the same

BITSTREAM-dts core vs LPCM MA with ps3 volume level on normal= they both sound the same

BITSTREAM-dts core vs LPCM MA with ps3 volume level on +2= MA sounds better

DOLBY DIGITAL: BITSTREAM VS LPCM with ps3 volume on normal= bitstream sounds better

DOLBY DIGITAL:BITSTREAM VS LPCM with ps3 volume on +2= they sound the same but bitstream sounds better "only" in action scenes(gunshots,explotions,car crash ect)

LPCM-dolby digital vs dts-ma with ps3 volume on normal= MA sounds alot better

LPCM-dolby digital vs dts-ma with ps3 volume on +2= MA sounds even better

BITSTREAM-dolby digital vs LPCM MA with ps3 volume on normal=MA sounds a little better

BITSTREAM-dolby digital vs LPCM MA with ps3 volume on +2=MA sounds better

hmm..well cool i guess, i don't feel so bad for buying a receiver a few years ago with no hdmi stuck win the dts core

dts-ma does make a differnce to me, it sounds so good.

My only question (which I pretty much already know the answer to) is...did you level match? That means you need a sound meter to determine that the volume is equal from bitstream to LPCM, etc. Otherwise, louder will likely equal better to a lot of people. LPCM from the PS3 is lower in volume than bitstreaming DD or DTS to a receiver. The sound is bit for bit exactly the same (LPCM from DD or DD bitstreamed).

Keeping the volume knob at the same level, between LCPM from decode DD and DD being bitstreamed on the PS3, will not achieve an accurate result. But, thank you for going through all the trouble.

no i didnt level match, but i thought this would give people an idea of the codecs when compared.

Anytime you pump up the volume, it'll sound "better" than if you didn't. This is science fact. What you may wanna do is play this as close to reference level as you can - that's 0dB - and do not change the volume after it has been set.

I believe you're using a DVD to get Dolby Digital on DH4. Instead of swapping discs, rip a chapter of DH4 onto a flashdrive and play through that. You might also want to use some sort of audio analyzer to make your results more scientific.

no i was using BD.

[turboLAZER]

has anyone compared the dolby truehd track to the DTS HDMA on Close Encounters

[saprano]

I also think the diffence in sound in these codecs has to do with how it was mixed from the studio? cause jarassic park DD sounds better when decoded by the ps3 than my receiver. but as you can see here with die hard its the opposite, unless i change the ps3 volume to +2. and even then the receiver still has more puch than the ps3.

Interesting. Didn't know that Fox included DD for their Die Hard movies.

They have Spanish and French 5.1 DD, but no English.
