PS3 audio support?

There is BD, DVD, SACD, CD, Dolby True HD, DD, dts(?), Bluetooth, HDMI logo...

Does this mean PS3 do not support dts-HD? or HD word leaves out?

I'm thinking all of those things aside from DD and DTS are only available via HDMI 1.3. The only problem is that there are currently no receivers that support HDMI 1.3. So if you want advanced audio from the PS3 you need to spend a crapload on a brand new receiver either at the end of the year or early next year.


If you're that interested in the new audio, the HD-A1 gives them to you right now with the receiver you already own.

audio being played through blu-ray is still better than regular dvd audio no matter what receiver you have. as far as the dts hd ma and dolby truHD you will need a compatible HDMI receiver, however if you dont have HDMI 1.3 you can still get dts HD which is even better than regular dts just by hooking it up to a old HDMI receiver. not sure about dolby though.


check out the dts website for info on compatibility and benefits you can get just by using the dts hd audio track on blu-ray dvds. and the ps3 definately decodes these.

DD TrueHD is decoded within the PS3 and will be passed through HDMI 1.2. DTS HDMA is passed through HDMI 1.3 and is not internally decoded.

See above. TrueHD and DTS HD (not HDMA) decoded as LPCM does not need HDMI 1.3. Just needs a receiver that can receive 5.1 or 7.1 LPCM via HDMI 1.2 which costs about US$250 the cheapest.

TrueHD on HD-DVD is at 16-bit/ 48kHz, which is the same sampling rate that LPCM 5.1 on BD is right now. So really, BD gave you lossless audio first.

wow. Is it real that PS3 could decode True HD? although dts-HD is pass through via HDMI 1.3,

why there is no dts-HD logo? PS2 can't decode dts but it has dts logo.

I didn't know it could give TrueHD over HDMI 1.2, but that still entails just about everyone buying a new receiver, and one that still doesn't support the other codecs.


Do receivers that have HDMI switching actually use the signal? I assumed it was just a feature and doesn't actually work as an input. If not, then I've never even seen a receiver that can use HDMI.


Good point about PCM, but it's such a space hog that it crowds out too many things.

That is the DTS-HD logo. The swirly thing in front of the "dts" is specifically used to designate DTS-HD soundtracks. I have some HD DVDs with that logo, and reading the fine print, it tells you that's what it is.


Keep in mind DTS-HD is not DTS-HD Master. It is lossy, but in-line with Dolby Digital Plus. DTS-HD Master is lossless.


A point of interest: Formerly, SACD was only passed through 5.1 analog outs. Does the PS3 come with a proprietary cable that breaks out to six RCA jacks for audio? If so, the lossless tracks decoded to PCM can be passed to an amp this way.

IMO, I think you need to spend around $900 for a quality receiver. But then at this price your better off waiting for the 1.3 version.

In all likelyhood, the multi-out will support two channels at most. There's also an optical out you can use for 5.1, but otherwise you will have to rely on HDMI.

No info yet on AV MultiOut to include 5.1/7.1 audio analog out.


Optical out only for CD, and standard Dolby Digital and DTS out.


The DSD can either be converted into PCM and output via HDMI or the DSD stream can be passed through to a DSD-compatible receiver. This feature, I believe, requires HDMI 1.2 at the least.

So just to get a definite answer,


The PS3 will decode Dolby TrueHD internally over HDMI 1.x

The PS3 will NOT decode lossless DTS internally over HDMI 1.x

The PS# will deocde DTS-HD over HDMI internally over HDMI 1.x.


PLEASE CORRECT ME IF WRONG!

The current literature I've found supports this.

LPCM does not require HDMI 1.2, only HDMI 1.1. HDMI 1.2 allowed for one bit DSD streams, 1.1 already supports multi-channel PCM. It is what Toshiba uses and most new receivers already support.


TrueHD on WARNER HD DVD is 16/48. Universal uses full 24/48 if the master has it. All of their DD+ releases have been using the full resolution of the masters, and so have their DTHD.

The PS3 is capable of decoding up to 7.1 channel Dolby TrueHD, which can be seen in this press release , and sending it out over HDMI 1.1 or above. As seen in the attachment to this post the PS3 can decode DTS and output it at 2 channels, which makes sense considering it only has stereo analog output, and can send the DTS bitstream over either optical or HDMI. Also I believe that the DTS-HD MA bitstream can be sent over HDMI if connected to an AV receiver that has HDMI 1.3 inputs.

Just curious but how many Universal HD DVD discs have used 24/48 encoding for the Dolby TrueHD audio track?

Also I am pretty sure that DD+ is only capable of 16/48 audio encoding and I remember Roger Dressler saying that a few months ago.
I don't believe this is accurate. Cjplay has alluded several times to the question of using 16/48 TrueHD over 24/48 DD+, since both use about 1.5Mbps average bitrate.

According to the HDMI website, here are the formats that HDMI supports:


Q. Does HDMI support Dolby 5.1 audio and high-resolution audio formats?


Yes. From the start, HDMI was defined to carry 8-channels, of 192kHz, 24-bit uncompressed audio, which exceeds all current consumer media formats. In addition, HDMI can carry any flavor of compressed audio format such as Dolby or DTS. (Such compressed formats are the only multi-channel or high-resolution audio formats that can be carried across the older S/PDIF or AES/EBU interfaces.) Additionally, most existing HDMI sources can output any compressed stream, and the newer sources can output uncompressed 6-channel, 96kHz audio from a DVD-Audio disk. There are A/V receivers on the market that can accept and process the 6- or 8-channel audio from HDMI.

A little more information for you...


Q. Does HDMI support Dolby Digital, DTS, and high-resolution audio formats?


Yes. From the start, HDMI was defined to carry 8-channels of 192kHz, 24-bit uncompressed audio, which exceeds all current consumer media formats. In addition, HDMI can carry any currently available flavor of compressed audio format such as Dolby (including Dolby Digital EX 7.1, Dolby Digital Plus 7.1, Dolby TrueHD) or DTS (including DTS-ES 6.1 and DTS-HD Master Audio). (Such compressed formats are the only multi-channel or high-resolution audio formats that can be carried across the older S/PDIF or AES/EBU interfaces). HDMI 1.3 adds additional support for new lossless digital surround audio formats Dolby TrueHD and DTS-HD Master Audio. Additionally, most existing HDMI sources can output any compressed stream, and the newer sources can output uncompressed 6-channel, 96kHz audio from a DVD-Audio disk. There are A/V receivers on the market that can accept and process the 6- or 8-channel audio from HDMI.

I believe that only Dolby TrueHD has a variable bit rate since it is a lossless audio codec. As for DD+ I know that it can not go over 48-kHz though I think you are right about it being able to encode at 24/48. After double checking the post that Roger Dressler made he was only referring to whether it could do 96-kHz sampling.
