Nice one JI!
DVD audio standards are still up in the air, but promise (hopefully) to come down soon. For our inaugural question, we want to know what you prefer: fewer channels and longer playing times, or multichannel high-quality sound with shorter playing times.
Has the industry considered two channels thru four speakers? A fader control would adjust the front-to-back balance just like a car stereo. I'ver heard this format many years ago, and if my memory serves me correctly, this arrangement provides a very nice perception of depth and images. It's an old and simple idea that just about everyone is familiar with from their car stereos. Consequently, it would be easy for most mass-market consumers to adopt. Additionally, it would be completely compatible with the current mult-channel hardware and would allow audiophiles to upgrade thier two channel systems into a nice two-channel, four-speaker system.
Realistically, I believe 20bit resolution at 48kHz with 5 or more channels is do-able and adequate for the home. Studio engineers need a couple of bits reserved for the 22 to 24 bit recordings they are making now. DD at a high bitrate (640 or above) should also be included. The best solution is to allow the system to broadcast its parameters via software, and have the hardware play back at the highest quality, or at the listener's discretion.
From what I understand of DVD, we don't need to compromise.... Why can't we have it all! High Quality Multi-Channel AND long playing times. Your question implies we must compromise (OK, there has to be shorted playing times for more channels, but shorter compared to what? If I can get 5 hours instead of 4... so what, but if it's 40 minutes instead of 2 hours, then it's a major compromise that we don't actually need.
I would hate to see an AC-3 only or DTS only format. If the big companies are going to be 'the' driving force behind the standard, then I would opt for a mix of formats (AC-3, DTS and 24 bit, if possible) on a relatively short, high definition disc.
Philips's DCC and Sony's Minidisc are examples of just how "out of touch" the big companies are with the true desires of their customers. With DVD, they will get to learn more lessons without "satisfying the customer", again at the consumer's cost.
I'd like to see a format that the decoding program written in Java is stored on the DVD, alone with the audio data. The player will be simply a simple device with a build-in Java Virtual Machine, which reads in the decoding program from the disk and execute it to decode the audio data on the same disk. With this, music companies can choose whatever encoding algorithm they like, as long as they provide decoder program on the same disk, and the consumers don't need to use different players for different format of disks all they need is a universal player with a built in Java Virtual Machine to execute the decoding program.
I'd like to see more than 2 channels and greater than 16 bit/44.1k sound. From what I have read DTS is supposedly very good (I have never heard it). I am a Dolby Digital person, but am always looking for an excuse to upgrade for sound quality.
If multiple channels are to be an integral part of DVD, then why the 5.1 channel alabatross that we all know to be inadequate? I can't see any good reason for fewer than 8, 9 with a seperate sub channel. Further, assuming that 16 bit is the hindering factor of current CD's and that 24 bit is the logical conclusion to ameliorate the problem, I would say the goal should be a minimum of 48 bit with a sampling freguency commensurately doubled. More concisely, I think all the choices given would be inappropriate.
Highest fidelity always. I regard surround sound an industry conspiracy to sell more amps, speakers, wire, etc. I have never heard a multi-channel set up that didn't obscure detail, when comparison to two channel was possible. In a video context, surround sound is an interesting effect that, despite the additional cost and complexity, does NOT meaningfully enhance the video experience. In a sound only context, it just muddies things up. Home theater is fraud.
4 Channels would probably be adequate--do we really need center and/or bass effects for high end audio? Also, not clear that 96/24 is really necessary. Maybe something like 66.15/20 would be good enough? But what is clear is that 44.1/16 is inadequate for music.
