Sample streaming ambisonic AAC files

[rondari]

All,

I've encoded a bunch of cool ambisonic decodes into streamable AAC files here:

http://www.ambisonia.com/tests/streamingAAC

The aim is to get a quality surround experience directly out of the browser. If you have Quicktime 7 installed and a surround sound card, you should be able to get glorious ambisonic surround.

Note: for ambisonic listening, you need to be in the centre of the speakers.

Please leave comments on that page (or here) about your impressions.

there's been lots of responses of people testing on OSX ... anyone got Windows XP with a 5.1 setup?

what's your setup? ... what kind of sound card do you have?

(and what's the quality of your speakers?)

what's your setup? ... what kind of sound card do you have?

(and what's the quality of your speakers?)I use my PC's on-board "Realtek AC97 Audio" chip-set. Which provides six analogue audio output channels. Which I connect to the analogue inputs of my Sherwood R-956R surround-sound amplifier and Kef speakers.

I got Windows XP and a 5.1 setup, too.
But that one is only connected via SP/DIF to the amplifier.
I cannot use the 5.1 analogue output, because I use the Mic and Line-In.

Will there be an wrapper/transcoder that can internally (Windows) grab the decoded six channels of any playback software and encode it to AC3/DTS and then put it out on the SP/DIF?

Or will the QT-Plugin be able to do that?

Hi scharfis_briain,

That's a problem I'd really like to be able to solve.

How to stream 5.1 to an AV receiver in DIGITAL. I dont think that a QT plugin would be able to do that (or none that I am aware of).

From what I understand it should be possible to use FFDshow to wrap the 5.1 channels into an AC3 or DTS stream which most/all AV receivers will be able to decode. The question is how to offer this easily.

I'd really like to be able to offer a stream where people can do this on Ambisonia.com ... anyone got any ideas?

I'm not sure if AC3 streams well? ... I'm guessing it might.

There _are_ AV receivers capable of handling digital AAC streams.. but there's not many.
