One more anecdotal answer. At the CdM studio we can switch orders from 1st to 3rd while mixing multitrack recordings with Ambisonic panning. The difference is not just obvious to anyone who has tried it, it's striking. I've tried many times to convert composers requiring spatialisation from using discrete channels to Ambisonics. It started to work when I offered 3rd order. The last example is a project I started working on just a few weeks ago. The composition was completely worked out in terms of using an ad-hoc speaker layout. On his first visit to the studio I demo'd some 3rd order mixes (both done locally and kindly provided by Joern Nettingsmeier), and let the composer play with the panning etc. He was converted in no time, and has completely rewritten the spatialisation (which will be performed 'live' in a concert later this month). > More interestingly for us, of course, was that you can get 3rd order > localization from 1st order material with the harpex decoder. I'd like to take with some grains of salt. I wonder, how would Harpex deal with a choir covering almost a semicircle and signing unisono (e.g. Gregorian). Converting this to the sum of two plane waves just doesn't make sense. This is actually something that works well in 1st order, but still works a lot better in 3rd (tried it using 5 panned spot mics).
