Thanks for the effort and upload.

They sound good on my home-theater-system and the Audi's Bang & Olufsen.

I'm just learning how to create 5.1 FLAC myself. May I ask how/where you originally found all these tracks in DD5.1/AC3/DTS form?

Tesla1856

Thank you for uploading.

I wonder where the original 5.1 channel Doobie Brothers tracks came from?

Funz51

I really don’t know, these were demo discs for Acura in the past 10 years.

Tesla1856

Thanks all for the info (just re-read the thread).

1. I'm sure I can live with these specs. I'll try changing my work-flow for this result (instead of something more extreme). I would rather do than than try to manage multiple ripped-FLAC copies.

2. Yeah, even on my nice home theater, hard to even say 96kHz is much better than 48kHz when you have 5.1 coming at you from all directions (6 discrete channels). I've found that what makes more of a difference is the better pro studio mix (as often available on these SACD and DVD-A re-masters).

Tesla1856

Found them ...

Doobie Brothers - The Captain and Me - SACD (2011) - Official remaster of original album released in 1973.

Tesla1856

I had just started, so I went back and used your suggested specs.

For the SACD that were identified in online db (getting meta-tags filled in) it was easy to just go back and re-rip them.

However, the DVD-A, BD-A, etc. are a different story. Those have to be manually edited. But they are already 96kHz/24bit 6ch FLAC files (and perfectly tagged), and it's just a slight down-sample, so instead of starting-over ... I used a the SSRC DSP re-sample at 48k and ended up with perfectly fine sounding 48kHz/24bit 6-channel FLAC files (with all file names and meta-tags left intact). The audio and channels "look right" in Audacity and MediaInfo . Most importantly, they still sound great.

So, you are sure that 96kHz/24bit 2-ch (stereo) FLAC files play fine on Acura ELS (current and going back to at least 2014 RDX/MDX)? I have some of those also, and it would be nice to not have to mess with them.

And finally ... on ELS ... don't even stereo files get a slight "fake DSP" or "matrixed" surround treatment (when you want it)?

I am talking only 2019+ RDX. That is my test bed. 96/24 is max for stereo. 48/24 max for 5.1. If you set the DTS on in the menu's, DTS will be applied and sound will be more filling. Otherwise, it is plain stereo, kind of, because the dsp distributes the sound into 5.1 surround. so no, not perfect stereo because you have more than two speakers. The dsp does a good job of distributing the sound even on a plain stereo track w/o DTS.

I read that the system uses one of 13 'profiles' to manipulate the recording depending on how good the source is. I have the link posted elswhere on here.

Not really. The SACD is from Japan and is a repress of the original 2001 DVD-Audio disc with a new 5.1 mix by Elliot Scheiner.

However, all 4 Doobie Brothers Quadraphonic albums were recently released by WB/Rhino on Bluray 4.0 audio discs that can be ripped to 24/48 Zero Compression flac to play beautifully in the ELS 3D systems in the RDX's (19-21) and probably in the TLX and MDX with the 3D USB systems.

Tesla1856

1. Right, a Japanese SACD. Not sure why it says 2011 instead of 2001. Maybe a re-printing. 2001 would make more sense as I think the Acura set was released in 2007 or there-abouts.

2. Interesting. Quadraphonic huh? I wonder why. So with quad the Center and LFE are empty channels ?

oblio98

1) In 2011, WB/Japan released 10 5.1 Surround SACDs that were originally released in the USA as DVD-Audio's in the early 2000's. They came out in 2 waves of 5 each. The only difference between these Japanese SACDs and the US (and rest of the world) 2001+ DVD-Audio's is that none of the bonus material was included as the SACD format did not allow for video or other extras.

2) The WB Doobies Quadio box (and the earlier Chicago Quadio Box) was created from the original quadraphonic masters released in the mid '70's. When listening to quad mixes in the Acura's ELS 3D system, you must edit the wav files and create an empty center and LFE channel or the surround will not work. The system will merge the tracks into a stereo mix.

There are hundreds of quad titles that were released in the 70's, many of them having been reissued on SACD and/or DVD/DVD-Audio. Seek and you might find.

I'm kind of late to the party....is there any way you could re-upload those two albums somewhere? The old links seem to be gone. No hurry.

Thanks!

Funz51

you are the second person in one day that asked for these, the day I took them down.
I will put them back up…

RaptorNation

Appreciate it

CWCJR

I am using a Mac and right clicking only downloads an HTML suffixed file that can't be opened.

Downloaded, thanks again!

Hi Guys, Just got 2022 MDX ASPEC and can't get any 5.1 files to play. The vehicle just says can't play this format. I've converted a bunch of my own files and used the ones uploaded here. Nothing seems to work. Any ideas? I'm using a Sandisk 1TB fall drive exfat.

ELIN

1) Typically there is only one USB connection that is "smart" and can play files. All other USB slots are for charging only. Are you using the right one?

2) It is well known that when using Wireless CarPlay/AA on the MDX, you can't use the USB to play music files simultaneously. In this regard, the limitation is the same for RDX and TLX.

dblwishbone

Believe it or not, though technically the OS supports it the system prefers FAT32. FLAC files also need to have 0 compression and be 48Khz for 5.1, max 96Khz for stereo.

gtgt

Thanks, Tired the fat32 originally and it didn't work. You're right with the wireless CarPlay it won't let you use the USB slot at all. This is so frustrating. Can't tell you how many times I've gone back and forth to the mdx in the past 6 years trying cd's and usb sticks just for them to fail. Wish they would make much more straight forward rather that jumping through hoops. Honestly the car ca see the files, just won't play them. I know they are correct as I downloaded some of them from here and everyone says they work. Has anyone tried resetting the entertainment head to factory settings?

Some positive news about 5.1 audio becoming more mainstream. Hopefully Apple enables this in CarPlay in the future. It would be awesome to listen to 5.1 audio via CarPlay, especially if Apple moves alot of their library to 5.1. Even if it's not 5.1, I'd look forward to hearing lossless 2 channel sound on my RDX.

Spatial and Lossless Audio coming to Apple Music

bbstenor

5.1 Apple Music would be welcome, but note that it says “thousands” of tracks across many genres. As others have said, true 5.1 studio mixes are not common, and many times are not done by the same engineers who recorded/mixed the tunes originally. And will it always be Dolby Atmos or just a synthetic approximation, like the disappointing DTS Neural whatever in the RDX. I’ve had 2-channel lossless from Amazon Music HD since last summer. The price was low, and they just announced today that there will no longer be an upcharge for HD. Win! I’ve tried the 5.1 demos (thanks, obblio!).There is already a world of difference to my ears with just 2-channel on the ELS 3D system, so I’ll stick with stereo. (I’m so old I remember when you had to choose mono or stereo when you bought an LP.) No going back to lossy AAC/mp3s.

WunderWagen

Well, I know in the traditional High Fidelity groups for home audio they only use true 2 channel stereo... they consider 5.1 only for movie audio. LOL

oblio98

Here's something that I will post for a VERY SHORT TIME. It's the track 'Seven Bridges Road' from the Eagles "Hell Freezes Over" album. It's in extreme 5.1, mixed by Elliot Scheiner. Some of you may already have this, but I am betting there are a lot of you that have never heard the 5.1 in the RDX, so download this file, put it on a USB stick, and enjoy.

This mix is very discrete, as the 5 Eagles vocalists are spread out around to each channel of audio, as follows;

Front Left - Don Henley
Center - Joe Walsh
Front Right - Glenn Fry
Rear Left - Don Felder
Rear Right - Timothy B. Schmidt

When you get this in your car, sit in your driveway, play the track, then play with your fader/balance in the car. You can use it to hear each one of their voices exclusively if you do it right. It's very cool.

Anyway, this is a limited deal as I am not a pirate or a bootlegger, I just want you all to hear what the car can do. Once you get the file, please share it with other RDX folks. I wish there were a way where we could buy stuff like this, I would scream from the rooftops telling everyone where to go to purchase 5.1 audio for the Acura, but sadly that is not possible. What a waste.

Anyway, here's the link to the file, and PLEASE, let us know how it works out for you and what you think. Once the link is dead, it's gone.

^^^^^^^^^^
Much appreciated. Thanks!

EFR

Thank you so much....again. And agree with the comments, of course, about wishing you could buy this stuff. Very excited about the Fleetwood Mac 'The Dance' album that someone made available recently, only to find out it was not in a format that the RDX could play. Still don't understand, but am sure it's economics and demand related, that you cannot buy via an Apple I-Tunes type website, 5.1 individual songs.

oblio98 - Thanks again. I’ll give it a play tomorrow.

CWCJR

Thanks so much. It does sound GREAT!!

oblio98

Here'e the complete Norah Jones super discrete 5.1 mix that someone was asking about. It's the entire song. This is NOT the same mix as the SACD.
This mix is not commercially available anywhere

Link available for a short time, for demo purposes only

And thanks again. Sounds great

Tesla1856

Looks like I missed this one, but I did get the recent Norah Jones track (so thanks for that).

I have Eagles - Hell Freezes Over on VIDEO-DVD. It's live-video with a proper DTS (6 discrete tracks). Yes, now I see this bonus track. Says it's DTS-5.1 but (strangely) audio-only. It's would be strange if it was mixed this way, but I'll take your word for it for now.

I have an established work-flow to get tracks like this extracted and saved a high-bit-rate 6-channel FLAC files. Just haven't got around to doing this one though. To me ... one (of the many) cool things about Hell Freezes Over is that Don Felder is still part of the band.

RiotfunK

Is there anyone on here that can throw some compatible albums on a thumb drive for me. I’ll pay you to make me one. I have found some samples online that worked but no full albums etc. I don’t have access to any physical formats or any ways to rip them anymore like dvd a/sacd etc. thanks

Padre Dave

Not knowing your age or preferred music style, I recommend ProStudioMasters.com as a place to find music in .FLAC format. They carry full albums and their prices are pretty reasonable, at least to me.

RiotfunK

Classic rock, jazz stuff like that. I’ll check the site. Probs what most on here listen to. Plus there’s not that many rap albums in 5.1. Although OutKast has one which would be sick

RiotfunK

I was able to get some 5.1 jazz and some others for the time being and it is a far better listening experience than stereo through this system. I’m assuming it’s cause the dsp/amp pushes more power to the discrete channels than through stereo. It’s just much clearer and removes the middy bleed you can get with regular tunes playing. The system sounds good regardless but the clarity difference is very noticeable to me. Others maybe not, but I enjoy good sound and it is impressive the difference. Surprised dealers have no idea that this was a thing. I was told the 3D was because of the roof mounted speakers etc. kinda wish I still had all my sacds/dvd a discs from early 2k. Thanks to others on here helping with this. And if anyone knows where I can get the dire straights brothers in arms 5.1 album let me know. Have original press on vinyl but want to hear it in all its goodness. Either way enjoy the beats peeps

Tesla1856

Tried to PM you but it said your box is full. Clear some space.

JB in AZ

Its been about 6 months since I last drove the '19 RDX Advance...The audio system in the vehicle that replaced the damaged RDX ('21 Corsair) is very good, but alas, doesn't sound like the 5.1 does in the RDX. With this said, I don't miss it (the RDX or the 5.1) It was very enjoyable to listen to as a special treat, and I fully appreciate and thank those here who provided the information and the tracks. For my routine car driving/listening, the Corsair does the trick for me. Very happy with things working as they should.

I’m new here so it won’t let me pm

Have you copied these to a thumb drive yet?
