Wait, there was a debate? I'm in favor of lossless audio whenever and hope that this new audio format makes its way into the next wave of movie discs. I just doubt that they'll make it onto current DVDs for movies since they're already pressed for space.

No debate. Don't make me bring out the banana again.

Yeah, that is lossless. But this thread was started about a new lossless *compression* for video. Like the shn/flac of the video world. Of course, we got a bit sidetracked along the way, but doesn't that always happen?

actually, a good ear can hear down to 16 Hz or even down to 12 Hz. My Sony Studio Professional headphones go down to 10 Hz and at that point it just sounds like 10 beats per second and not really any sort of 'sound'. I really recommend those Sony's btw

I have the Sony MDR-V150s. What do you have?

Also, great to see that there is no debate over such an already pre-determined topic!

Even the banana is now dancing!

He's doing the "Lossless Audio Dance" or something like that.

The lossless codecs HD DVD will support are 2 channel LPCM, 2 channel MLP and DTS HD. The audio codecs for Blu-ray has not yet been decided.

I'm a bit suprised that HD DVD will not support multichannel LPCM/MLP like DVD-Audio.

I'll still take the 2 channel LPCM over the the other ones anyday.

Re: MPEG-4 Audio Lossless is served

Hey
Until Storage capabilities meet requirements on portable media MP3 etal will be around...

I still have my archive of WAV, FLAC & SHN but I travel with a 60GB iPod... It gives me a the flexibility to have yes, quantity... With the advent of technology like juke joint and affordable TByte drives my home will soon be loss less again but for the foreseeable future my car my train and plane will be 192kbs.... These are trade offs but having them is what makes this stuff usable everywhere.

I have a demo of an environment where I can stream FLAC to my cell phones real player soon the iPod in its current form will go away.... Hey the 8 track was ubiquitous that quality sucked then came cassette...Dat...cd...hdcd...dvd-a It will all catch up again but the days of 2 channel critical listening are going the wayside of the 5.x It is a storage issue.

A

Re: MPEG-4 Audio Lossless is served

about video capturing from analog sources it would be nice to get an quality upgrade for DV format which is about 5/1 compression allready. fair prices for that equiment, available for the general public/for masses etc.
