First off, recording a 24 bit file with 20 bit converters IS better than recording 16 bit files with 20 or 16 bit converters in most cases. There is a HUGE advantage to recording 24 bit files while only utilizing 20 of the bits. Plus, you're not using that much more space by recording 24 bit files. That really shouldn't be an issue when anymore anyway.

I still want to stick with my picture analogy though. When you increase bit depth, you get a much more dynamic picture. It's the same thing as bits with a color monitor for instance. With lower resolution monitors you could still capture red blue and green, but the detail of that red blue and green was a poor quality because there weren't enough shades of it. Let me explain a little better, true we're not increasing sample rate, so we're not capturing any more frequencies, but we're getting a much more dynamic and smooth picture. Especially with the upper frequencies because they essentially turn into triangle waves when the signal gets too quiet. With increased dynamic range you get a much smoother and accurate picture of the quiet or dynamic things in a recording. So that's why I use the picture analogy.

I guess it would make more sense if I said that 16 bit is like taking a picture in the dark without a flash. You get some detail, but because the light is too low you get a really grainy blurry image. Same as sixteen bit when the signal gets too low, you get a grainy distorted sound, especially at high frequencies. Adding 24 bits is like increasing the cameras ability to take pictures in the dark. It's actually the equivilant of turning all the lights on in the living room. You have a much more enhanced picture. 20 or 24 bit. 20 bit is tens of thousands better than 16. 24 bit is literally millions better than 16 bit.

Believe it or not folks, 16 bit sucks. CD quality, sucks. Why do you think that CD's these days are squashed, limited, steam rolled to the maximum. Well, the first reason was to limit the effect of 16 bit by maximizing dynamic range. Basically taking out the issue of things getting quiet and distorted. Second reason is, now that we expect CD's to be loud, that's the what we, the consumer expect. If we get a quiet CD now, we think it's quality is lower. The truth is, we're really getting lower quality recording because they lack dynamics. 24 bit could help change that. I hope that DVD audio takes off and soon. In fact, CD's sound so bad that people now think MP3's are OK. That's just another horrible step in the wrong direction.

I'll step down now, I hate bit reduction. Could someone make that into a bumper sticker for me??

I think you're preaching to the choir.

OK, 16-bit sucks. But you have to remember that 16-bit CDs were concieved in the early 1980s when 8-bit computers were hip and cool and 64mb of RAM was unheard-of.

Unfortunately it seems to take 20 years to get people to go from mono to stereo, from AM to FMradio, from 8-track tapes to CDs. We'll probably see a movement sometime in about 10 years to something better (24 or 32-bit.... storage capacity is increasing nicely with DVD's now storing 5-10Gb versus CD's at 640Mb.)

The biggest problem is that, unlike you and I with trained ears, the vast majority of the "general public" don't see any advantage to buying all new music when they can't tell any difference on their $60 boomboxes and $100 car stereos.

I guess the key would be educating the public. DVD should be easy to implement. I don't understand why they haven't begun to do this. DVD players play normal CD's and DVD's. There's no new system to buy. Why don't they just start putting out DVD's rather than CD's?? I don't really keep up on the whole DVD audio thing, but I'd love to know what their action plan is. I agree, most people don't know the difference, and I think they would if they weren't buying the cheap boombox's.

Good points.

I agree. I think the holdup in producing DVD audio might be that record companies are waiting to see which hi-resolution format wins out (DVDaudio vs. SACD). It must cost a fortune to release material on both formats! I would LOVE to see SACD assume the front spot. It's as sonically perfect as is possible right now, but you need to play it on an SACD player to get the high resolution data from your disc. I think DVDaudio, played back through a standard DVD machine, will easily win this fight (seeing as every new technology rests on the fickle whims of the general public, and their wallets). Not that I'm complaining (too much:)). Any 24 bit medium would be great, and DVDaudio is no slouch.

I agree 16 bit SUCKS. I have been recording in 24/96 since it was available. I have a full album ready to go. but I refuse to place it a medium like CD. I almost always mix my music in 5.1 or 7.1 surround. Until an affordable medium exsist for consumers to play it back on I will wait, Or release it on the web as multi-files for download. I now this sounds unrealastic, But I Hate CD's and MP3's (what step in the wrong direction that was)
