All, I've blogged about the new free-account structure here: http://blog.ambisonia.com/2009/10/16/can-i-still-think-like-a-user/ It may not be of interest to...
I think this structure is a sensible one. Much better than the recordings dropping off the end. I'll hopefully be uploading a first and second order example...

... great, thanks for the confirmation. ... I dont believe the current transcoding code will work with 2nd order. It should be relatively easy to lose the 2nd...
ok, I'll see if I can knock together a 3rd order file. My panners kick out furse-malham sets at the moment, so I'll need to do some tweaking...... cheers Dr...

Bruce, the UA spec in its current form is here: ...
okey dokey. One quick question. The bit that mentions all UA plug-ins must implement the full spec. But this implies all 20 channels. A panner shouldn't...

... Yes, good point. I'm trying to think (out loud) if it is 'valid' (or useful, or 'within the philosophy') for UA to generate synthetic material in 1st...
I made a 5th order UA file a while back (this was before the change to 1 and 3 only). You could lop off the 4th and 5th order channels to get 3rd. and add 4...
... you're in a 3rd+1st-order context, channels 1-4 of the output of the panner should be routed to channels 16-20 of the 3rd+1st-order signal. If you're using...

... Sorry, I mangled that badly. I was thinking about was the notion that one could use a 3rd-order panner as a 1st-order panner by taking channels 1-4 of the...

Aaron, A 3rd order sample file would be extremely useful. We need a sample file, not just for testing the upload and transcoding on soundOfSpace, but also for...
... ah, ok, so it is catering for the use-case where someone would be panning content explicitely for the 1st order part of a combined 3+1. You are right. Its...
Here's that other combo drawn up properly in a table: http://docs.google.com/Doc?id=df4dtw69_85hs2hvsdx This would make down-mixing easier ... but has other...
The more I think about this, the more I think the best way is to say "just implement everything as 3rd order". Then, as Aaron suggests, those 16 outputs can be...
The file robo-jo.ua can be accessed here: http://ambiboots.audio.s3.amazonaws.com/etienne/robo-jo.ua It is Aaron's walkaround in 3rd order, compressed with...
here's how I'm covering it in the spec: (http://docs.google.com/Doc?docid=0ASR5ajtUjzNQZGY0ZHR3NjlfODFkc2dtZ3FjMw&hl=en) Software Implementation Implementation...
This seems sensible, (if I'm following this correctly, of course!) and is how I'm making a 20 channel file from my 3rd order panned + 1st order reverb system....

... good catch, its an invalid UA file (I just threw those values in there without looking much). Once WavPack 4.70 comes out, the plan is to wrap the wavpack...
Bruce, I'm talking to David Bryant lots about getting the right settings for appropriate ambisonic compression ... once you've got a multi-channel wav made can...
... The crux of it was that you cant really mix 1st order stuff directly into the first 4 channels of a 3rd order stream. Well, you can under certain...
