When I went to visit my dad 600 km's away I purchased some foreign magazines and among those were an american Home Cinema Mag called Home Theater Buyer's Guide which is one of the best mags I've read on the subject. Anyway it contained a lot of technical specs concerning Dolby Digital which contains six separate sound channels which totally uses 384 kbps. That is 64 kbps per channel which is exactly the same used as "default" when we encode our mp3's. We actually encode them at 128 kbps but the are in stereo so we use 64 kbps per channel. When we encode mp3's we use mpeg-1 layer-3, but I think Dolby Digital uses mpeg-2 since they use it for image, but anyway my thought was that the quality should be quite equal anyway. Much of the discussion was wheather the Dolby Digtal with 384 kbps was enough for audiophiles or if DTS (Digital Theater Systems) with its 1 411 kbps should be industry standard instead. This whole discussion was around DVD-players and I think it's remarkable what have been achieved with compression both lossy and lossless. Most admirable is the lossy such as MPEG and JPEG. As some smart person sad somewhere - it's not the bandwidth expanding that will be the big technical achievement of this decade, but the compression that will allow more data to exist/flow on the same bandwidth/storage area. Some time before this a went to Knutstorp and was given a chance to sit in a Lamborghini Diablo and I just want to show you the picture. Click to see a bigger image. There were many other cars as well such as Ferrari 512 tr, 355gts, 550, lotus esprit, AC Cobra and a whole bunch of porsches. I'll put a page with some images from that event here soon if there's a demand for it. I'm leaving Sweden soon for one week vacation in Portugal and will be back 1 october. To all friends at work - have fun (hope it rains all week, heh ;-) And yes, don't forget to have a look at my raytracing section with some new images. - Pixelizer
