The AES Show being about.. well, audio engineering ;-] there were some interesting booths not usually seen at the more MI-oriented shows we normally cover.
One that caught my eye was from Portuguese company Jocavi who manufacture a wide and colourful range of acoustic treatment products, aimed at spaces from small rooms to huge concert halls.
The also do a range of off-the-shelf 'treatment packs' which look great for the more 'project' end of the market.
The diffusion panels they had on display were made from a range of materials, from wood, clay paste and ceramic, to ABS and high density foam - and they looked great ;-]
There's lots of info and specs at their website.
