[SIZE=+1]I am researching the availability of a certain piece of equipment that I am not sure exists.

The project:

An audio test signal generator that would do the following:

[/SIZE]
  • [SIZE=+1]Provide internal generated, or accept external generated, basic test tones; pink and white noise and various sweep tones.

    [/SIZE]
  • [SIZE=+1]Output these tones via balanced/unbalanced analog outputs.

    [/SIZE]

  • [SIZE=+1]Encode the tone via DTS Master Audio and/or Dolby True HD to a specific output channel; center, surround, rears, subwoofer and output via HDMI.[/SIZE]
[SIZE=+1]The purpose is to individually evaluate the output of each of the 7.1 audio channels and test them from any source. Direct through the amplifier, through a A/V processor and again through the A/V processor with any EQ or room correction applies. Software and microphone to graph the results would be a bonus.

[/SIZE][SIZE=+1]Most A/V processor either show you a graph of what it thinks it will do to the signal or nothing, requiring a leap of faith that it is making the correct adjustments.[/SIZE]

If this black box exists, I haven't found it, but would sure like to have it.

What you actually want is a audio test disc (Blu-ray I suppose). You don't need a fancy piece of equipment to generate and encode the signals in real-time when you can accomplish the task with pre-canned test tones on a test disc. They are difficult, but not impossible to come by.

I, probably, own every A/V test disc I am aware of. While they do generate a variety of test tones, they will not interface with the analytical software to properly review the results.
