This wav plays back through proper "channels" using other software players (e.g. Nero, Creative MediaPlayer etc.)

MC settings: down-mix mode 7.1 (so there is no downmixing) all speakers at LARGE; all trims at zero;

When I playback the file (USB), many of the channels (as measured on the MC analog outputs with scope) are not correct.

I checked and 5.1 wav PCM is fine wrt correct channels being used.
I will send my sample 7.1 wav file to OPPO.

Just to be clear, the above issue with 7.1 is ONLY for media file playback. I checked using the AIX Audio Calib. Blu-ray disc using 7.1 24/96 LPCM and the BDP-95 MC channel mapping is correct for Blu-ray decoded audio.

There is a 7.1 24bit/48kHz PCM wav file from Microsoft for testing purposes (with sequential voice-over in each channel) available via this page (the 8 Channels Test File link near the bottom) . Also includes the corresponding wma pro MC file.
This 7.1 wav file has this voice annotation (clockwise channel voicing):
" Front-Left, Center, Front-Right, Side-Right, Back-Right, Back-Left, Side-Left, SubWoofer "
Here is a multichannel timeline view of this file (using Nero 7 WaveEditor). The channel designation is shown at the left. The vertical order of the channels as displayed is the actual packing order of samples in the wav file. The "BL/BR" (back left/right) shown corresponds to the Surround Left/Right channels of home theatre players/receivers while the SL/SR (Side Left/Right) correspond to SBL/SBR in home-theatre designation.

I'm not sure you'd want to hear a 1 Hz signal - it might be better just to feel it. I'm not concerned with low frequency hearing, I'm more concerned with high-frequency hearing. I want my 25-year-old high frequency hearing back. But from what I've heard at seminars, the only hope for regenerating the damaged hair cells in the Corti is going to be stem cells. Somehow, I don't think this is going to happen in my lifetime.

A 1Hz signal is the sort of bouncing a low-rider car does. Hearing it is not the issue. You see it -- as when all the fragile things in your room start bouncing. Well, to be precise, you'll hear the crashing and tinkling......

ETA: I actually know a poster here who has pneumatic floor bouncers installed under his theater floor, along with an incredible amount of dedicated amp wattage, to enable bass reproduction down to 5Hz.

I don't think it is just the damaged hair cells .... also stiff linkage, like arthritis of the ear :-) but I agree it will be later rather than sooner.

Another interesting possibility with wav file is that you can specify in the wav header where the channels which are interleaved in that file are STEERED to. Usually, for a 2 channel stereo wav file, the "target" output channels are FL/FR but this doesn't have to be so. You can change 4 bytes in the wav file header (the so-called ChannelMask) and specify that the audio is steered to the SL/SR or SBL/SBR for example (part of the RIFF/WAV file specification). However the BDP-95 I believe for wav media playback just disregards that channelmask and uses FL/FR if there are two channels in the wav, and if there are 6 channels, it again disregards the channelmask and outputs to FL,FR, C, LFE, SL, SR as is most normal ... which of course is what most people expect

I spoke to a Velodyne guy some time back about problems their customers had when certain discs were played through their Ultra 2 capable (below 20Hz) subs. The subs kept going into thermal protect.

Apparently these discs had incredible amounts of 16Hz noise on them, which the studio guys were unaware of since their studio monitors could not reproduce it. Some sort of ambient vibration their mics were picking up.

Orb Products Bring Netflix, Pandora, Amazon, Hulu, etc. to Oppo

http://www.orb.com/

I've done some experimentation with this (as part of Oppo Beta Testing) and it appears to work, albeit in a "new product" sort of way.

You buy the "Orb BR" disc for about $25. It includes a USB memory stick that you insert and set up as your Persistent Storage (instead of using the internal Persistent Storage in the Oppo).

Meanwhile, on a Mac or Windows PC you download the free "Orb Caster" application. Orb Caster actually contains the smarts for connecting to the streaming services, as well as providing the ability to access media files from your computer. NOTE: This is a processor heavy application, so be sure to check the minimum speed specs to see if your computer will suffice.

The third piece is user control. This is accomplished either with a "Mini Controller" app on your computer (included with the Orb Caster download), or a free iOS app "Orb Controller". I believe they also have an Android version but I've not played with that.

You fire up Orb Caster on your computer, and make sure it can receive incoming network connections. Then you play the Orb BR disc on your Oppo. Then you fire up your controller app -- whichever one you want to use. NOTE: All three pieces have to be running on the same, local network so they can find each other.

For password services like Netflix, you tell the controller your account email and password and it sends over and saves those in Orb Caster. At that point you can view your Instant Queue, or do Searches. When you select a program to play, Orb Caster establishes the incoming stream and re-streams that to Orb BR on your Oppo.

For media files, you tell Orb Caster which sets of files to index, and they then become available in the controller app. (Orb Caster can also act as a DLNA server, presenting your media files to the DLNA file playing UI in the Oppo itself.)

There are definitely still some strangenesses in all this, and I don't think the playback quality is quite up to native apps yet (given the same network speed in both cases). But as an alternative to no access at all, it's pretty cool!

Definitely something for you early adopters out there to consider. Folks who will only tolerate a bullet-proof streaming solution should probably wait until more reports come in from folks who've tried it.

NOTE 1: The latest version of Orb BR and Orb Caster supports the Oppo BDP-80, BDP-83, BDP-93 and BDP-95. The Orb folks still need to update all the pages on their web site to properly reflect this. Orb BR auto-updates when it launches. The necessary version of Orb Caster is the one available from the public download link on the Orb web site.

NOTE 2: For the BDP-93 and BDP-95, the native apps for Netflix and Pandora are preferable. But Hulu and Amazon access should still be interesting.

Greetings. I took the leap and bought an OPPO 95 so that I could benefit from the lossless codecs while keeping my Rotel 1098 processor. I am having a problem though with the surround back right and left channels. In the OPPO set up screen I cannot get a test tone out of the surround back right/left channels. I did troubleshoot and tried the FR/FL outs from the OPPO into my center back 1 and 2 inputs on the 1098 and I did get sound out of my rear back surrounds therefore it is not an issue with the 1098. I also plugged my surround back right/left from the OPPO into my FR/FL and go not sound out of my mains.

In the audio processing settings I have the Stereo Signal set as Front Left/Right so that I can benefit from the better DAC hardware.

I do have it set for 7.1 downmix in the OPPO. Any suggestions?

Check the firmware that came with your new player. Setup > Device Setup > Firmware Information. The latest stuff is the 0917 firmware. If your player needs an update, start there. There was a fix for Test Tone problems in the 0917 firmware.

(See the firmware history info in the first post of the 93 sticky thread at the top of this forum for change notes, links, and the version numbers for each firmware release.)

Move the cables from RF/LF at the back of the Oppo to RR/LR -- i.e., use a cable pair that's known to be good to eliminate the possibility that you have a faulty cable pair on your Rears right now.

If still no luck, give Oppo tech support a call

I have the correct firmware as it updated right when I hooked it up to the network. Tried the cable change and no luck. I will phone OPPO tech support. Thanks for the suggestions.

If you have the AIX Audio Calibration Blu-ray Disc, you can try the PCM 7.1 channel ID track (I just checked and it outputs correctly to all the BDP-95 MC channels. This would verify operation of the SBL/SBR channels (in case there is something wrong with the BDP-95 test-tone functionality).

There is also a 7.1 test on the Spears/Munsil BR benchmark disc.

If you don't have these discs, you can use the free Microsoft 7.1 PCM WAV channel ID sample referred to above with media playback. As I mentioned earlier, although the MC tracks are not properly mapped, you will get audio from the SBR channel to verify it works. (You will hear "Side Left" coming from the SBR channel and nothing coming from the SBL channel when you play the entire wav file).

I decided to create my own 7.1 24bit/48kHz PCM wav file for testing purposes. It voices over the channel number sequentially (in packed order) in the wav file. Any feedback from users with gear capable of 7.1 PCM wav media playback would be cool

Any idea when the 95 is going to be available on amazon? The 93 is there. I have amazon points to use and it would be nice to use them towards an oppo 95

"Never" is a loooong time!
Even if "Amazon" doesn't get the 95 from Oppo, who's too say other seller wont put one up for sale.

Well that kind of sucks, the 93 is there along with most other oppo models no reason to not put the 95 on amazon
post #6229 of 11026
And I'm sure some would like to see them at Walmart and that's not going to happen either. Any used Oppo 95 that shows up on Amazon is there only because the owner has never heard of Audiogon or other places where audiophiles, who would spend 700+ for a used blu ray player, shop. Amazon? not likely.

With the multi-channel config. set up as follows:
- all speakers LARGE
- SW ON
- down-mix set to 5.1

When I playback a 5.1 PCM wav file, the MC outputs correctly to the expected channels (in this case, the SW output appears to be a full-bandwidth channel).

If I switch the down-mix mode to 7.1, the channel outputs for 5.1 audio are the same (no "upmixing effect") as expected.

Now if the SW speaker setting is set to OFF, does this mean that the SW content in the original 5.1 audio is steered (with LF attenuation filter curve) to all other channels that are set at LARGE ?

If you have the Sub OFF, then any LFE goes to LF/RF on the multi-channel Analog outputs. The outputs are attenuated.

LFE is DISCARDED in the down-mix on the dedicated stereo Analog outs when they are set to operate independently of the multi-channel stuff.

--Bob

With Sub OFF, my 5.1 wav playback measurements show that the LFE goes to ALL the following channel MC outputs (not just FL, FR): FL, FR, SL, SR, SBL, SBR (in all cases the outputs are attenuated). I think that if SW is OFF, then ANY other MC channel set at LARGE will get the attenuated SW signal?

Looks like the SBL/SBR rear channels outputs on the OPPO are not working as I cannot get a test tone from them either. Will speak with the Canadian distributor tomorrow.
