Creating a BD Audio Test Disc?

[drfsupercenter]

What I'd like to do is create a burnable test disc for my surround receiver.

Basically, I'd create 8 separate 7.1 DTS tracks. Each one would play some sound (white noise or whatever) through only one channel.

What I want to do is create a menu that I can select a speaker, and it will play that test tone until I select another speaker. Basically, have it change the audio when I select an option.

I'm not sure how I'd go about doing this. I just need audio - I can make a blank video if needed, but then I wouldn't be able to see the menu :confused:

Or has someone already done something like this? I know there are some demo discs you can find on eBay and such, I have one of them, but it just plays the test tone sequentially and only for a couple seconds. It's not useful for testing WHICH speaker is being played. (My receiver had this weird bug where right and left were reversed)

A suggestion: You would use a audio editor like audacity and a microphone.
You record your own voice to a fs=48kHz 16bps mono track and speak the channel names "left front channel", "right front channel", " center channel", "low frequency effects" (with deep sounding voice to have something below 120Hz), "left surround channel", "right surround channel", "left rear channel", "right rear channel".
Split the recording into 8 separate files, each 3 sec long ( or whatever fits)
Now you open up a new empty 8-channel file and copy the 3 sec bits repeatedly onto the tracks, each track offset by 3s, interleaved by 7 pieces of 3s silence. 20 cycles or more, you decide. Channel mapping as required.
You get a 8 channel file saying "left front channel" in the left front channel, then "right front channel" in the right front channel, then "center channel" in the center channel etc.
Encode as multichannel .wav64. Make black video with length=cycles*duration*channelcount (20*3s*8=480s), mux using tsmuxeR.

Some Disney discs have this already, the test tones and calibration images are sometimes hidden bonuses (Easter eggs).

That's clever, and it might work.

What I did for now is create 8 8-channel WAV files in Audacity, each one has a minute of white noise on a different channel, so I have FrontLeft.wav, FrontRight.wav and so on.

I can hook my laptop to my receiver using HDMI and should be able to play those back.

However, I think the bug in my Onkyo receiver was specific to 7.1 DTS tracks, not PCM (since Blu-Rays usually don't have 7.1 PCM...)

The problem with the Disney test things is that they don't differentiate which speaker is being used, it just goes sequentially. I want to test my receiver by just hooking up one speaker output at a time so I don't waste my time crawling around plugging everything in just to find out it still doesn't work.
