I was asked a 4-channel work for an online-release - I' m now trying to figure out what the best way to "release" it would be..
For me personally, the first question would be "which four channels"? "What are their semantics, precisely?"
Like, how did you come up with those channels? What did you use to make them? How did you process them? What did you think you were going to play them over? And so on.
I am totally inexperienced in web-friendly file formats for such things..
In the Web, you prolly want multiple different formats at the same time, most of them being pure stereo as far as sound goes. Unfortunately...
- I could use mp3-surround -> but it' s only 5.1 and this could possibly cause problems
You will have to stoop this low. Then, stoop even lower: make the basic format something like 48-96kbps stereo mp3.
- I could use flac -> but I' m not sure if common media-players support it
VLC does, and it's common enough. But that's then *very* high bandwidth in comparison. If you do this one, I'd at least try 96kbps AAC (in stereo) or something like 224kbps AAC (in full 5.1), in the high profile, in between.
- I could try some video format (?)
They're basically the same, given a fixed picture.
what is paramount is that the casual listener can listen to the 4-channel mix without having to download nothing or in the worst scenario to download some specialized media-player which is flexible/easy to find and free.
They can listen to it, alright, so the paramount idea is to downmix it right. They are *not* going to get most of it without possessing the right hardware and setup, though. I don't, for instance.
So you really have to give us more details than that. Even for stereo listening. And especially for whatevermore you want. I'm thinking the usual 5.1 format could serve you well. From the ambisonic viewpoint, you could make it into G-format. But you really do have to divulge your signal format before we can do anything about it. :)
maybe there is specialized file-format/media-player or some lossy ambisonics formats for such things ??
Unfortunately there is not. We all want to will it into being, and it would be a hoot. Still, those gods of ours have proven reticent for some four decades, now. Apparently they like to try us faithful.
