I think you may have a fundamental misunderstanding of bit rate and bit size (or word length). The statment "24 bit just takes more sample snap-shots" is completely incorrect. If the sampling rate/frequency is fixed at 44.1 kHz, changing the bit size doesn't change the number of sample snap shots. There will ALWAYS be 44,1000 samples per second. The difference is that each sample will either be 16 bits or 24 bits. Regarding "compressed sound", you must have misunderstood me. When tracking, I can get away with recording at a lower level in 24 bit. I have enough resolution that I don't have to record as hot nor worry about clipping my converters. If I recorded at 16 bits, I would have to record hotter to get the needed resolution, but then might need to compress/limit before the converters to make sure I don't clip. Get it? I've been trying to stay out of this, but that first statement I quoted from you doesn't help your argument too much!
Well, you sort of got me on a technicality. Yes I misused the term "sample", but the fact remains that you're just dumping in more snapshots. I don't see any reason not to refer to the data represented in each amplitude as a snapshot also. It is effectively just that—more snapshots of the amplitude frequency, rather than more amplitudes. So each amplitude is represented by more snapshots of it. Do we need more bit depth though? The only problem with 16 bit was always the portion out of the human hearing range anyway. It was the stuff recorded between 19.5k and 22.5k that was getting a little distorted (more or less but feel free to call it jitter if you like.) Oversampling very effectively did away with the last 2,000 or so bits though which left us with a recording between 20 and 20k that was for all intents and purposes distortion free and clear as a bell. I really don't see where taking more or longer snapshots of the amplitudes will make things sound any better than taking more amplitudes themselves. Neither will help in my opinion. But as I've said before, eventually (in about two years) we'll all be ready for new puters with new soundcards and anything we get then will be quite capable of 24/88.2. And if you can record at that with no ill effects than you might as well whether you can hear the difference or not. Right now however, going to 24 bit recording means a lot of stress on the machines most of us have and I just can't see buying a new box with a ton of RAM, and a huge HD, and a Pen4 just to record at a higher bit depth or sample rate. If you have to go out and blow a thousand bucks for something that I know good and well isn't going to sound any different that's just being wasteful which is fine if you're content to keep blowing all your money on gear and live in your mom and dad's basement till you're 35.
Please understand what I'm saying. I'm not condemning recording at higher bit depths or sample rates. I'm condemning people saying things that are untrue such as "Your SB Live is a crappy soundcard and you'll never get professional sounds out of it." That's horse hockey as I believe I've already demonstrated (as well as many others have.) That's just being irresponsible. It's telling every kid that comes in here that he's got to go out and blow money he probably doesn't have on something that he'll never hear the difference in. If you can't get a great sound with a SoundBlaster or any other 16 bit card then you'll never get a good sound with a better one, plain and simple. Anyone that can't get an absolutely perfect sound with something like an SB Live just doesn't know what they're doing behind the board, period.
As to enjoying my SB, I only use it here at the house for little things. We have a Hoontech at the studio but still only record at 16/44.1 and we won't be changing any time soon.
Now as to your
acoustic guitar recordings, I too play mostly fingerstyle. I can't imagine
not using a compressor with one! How do you get a worthwhile sound on an acoustic instrument without a compressor? I've never in my life seen anyone do it. It's not that we're so worried about low signal levels or tape saturation/distortion (depending on if you're digital or not.) It's just that everyone loves that open, airy feel you get with compression. It just thickens things so much! I would NEVER think of recording or playing live without my DBX 160XT. I used to go to Winfield for the flat pick and fingerpick championships every year and one of the things most of us complained loudest about was the fact that they always used a crummy dynamic mic with
no compression on the guitars. They sounded awfully skinny like that and they actually recorded those performances and sold them on CD. I just couldn't believe it.
Of course if you're compressing your sound then record levels aren't a problem. If you're not compressing your guitar mic I'd highly encourage you to go out and get a good DBX or Valley People compressor. You'll never regret it and I just can't imagine getting a good sound without one. I don't think you can point to recording of
acoustic guitar (except for some older classical recordings, which usually sound fairly bad) that wasn't done with a compressor. Phil Keaggy, Doyle Dykes, Eric Shoenberg, Tony Rice, Doc Watson, you'll never find a recording by any of the top acoustic players without a lot of nice compression on it. It's simply a must!
