WHAT ARE THE DIFFERENES BETWEEN 16 BIT AND 24 BIT..
DOES 24 BIT HAVE MORE QUALITY AND SOUND BETTER?

Yes, 24-bit is of a higher quality and it sounds better. You will probably find lots of helpful information at this link:

The difference between 16 and 24 bits is 8 bits.

Bit depth refers to the length of the binary "word" that is used by the computer to describe a sample of digital audio.
You can think of it this way:
A 24-bit word describes a sample more accurately than a 16-bit word in much the same way as a number with 7 figures after the decimal point describes a value more accurately than a number with only 3 figures after the decimal point.
The result is that 24-bit digital audio is more of an accurate representation of the original analog signal than 16-bit and provides more clarity and fullness to the sound.
Hope this helps.

THANKS FOR REPLYING..IT HELPED ALOT..WELL EXCEPT FOR THAT 2ND ONE..BUT UMM I READ SOMEWHERE THAT WHEN YOU TRANSFER THEM ONTO DISC IT'S BACK TO 16 BITS BECAUSE MOST STEREO'S DON'T SUPPORT 24 BIT..

If by 'transferring back to disc', you mean transferring to CD, then yes, you are correct. The bit-depth/sampling rate format for an audio CD is 16-bit/44.1kHz. So, in order to burn a Redbook standard audio CD, the audio data or audio file must first be converted to this format. This is why, if you will look at the Render As function in Vegas or Acid, one of the format choices is 16-bit/44.1kHz Stereo. Also, notice that CD Architect will only accept files in this format - because it has to be at that bit depth/sampling rate before it can be burned onto a CD.
It's not your stereo that cares, though. It's the CD player.

What you want more info than what I gave you? I gave you the obvious answer it's 8 bits difference.....which is a lot of info if you know what that means.

Now let me explain what that means to you....For every bit you get 6dB signal to error ratio...or also refered to as signal to noise ratio (6 dB means twice as much, because there's actually twice the amount of numbers for every bit)2^16=65,536 and 2^17=131072...etc..2^24. ok, are you with me so far? A CD has 16bit audio, or a 96dB signal to error ration...which is derived from 6dB times 16 bits (16X6dB=96dB). A DVD has 24 bit audio. 24X6dB=144 dB signal to error ratio. 144dB - 96dB=48 dB= 6dB X 8bits (remember that 8 bits I first told you from my original post? There it is again)....so there's a 48dB difference in quality. Now...follow this (you have to think in log rythms)................
2X(2 times)=6dB, 4X=12dB, 8X=18dB, 16X=24dB, 32X=30dB,64X=36dB, 128X=42dB, 256X=48dB. 48dB means it's 256 times more accurate. Thus the resolution of a sample of 24bit audio is 256 times more accurate than that of a 16bit sample, or 256 times more the resolution as the other posts brushed on.

Was that a little more discriptive for ya? :-)

And in going back to 16-bit just before burning the disc, you may want to consider using noise shaping to move the dither noise from the sensitive parts of the musical spectrum. It can make for a quieter sound.

Lol, everytime you make a post beetlefan you kill me. Move the dither noise? Do you know what dither noise is? Could you explain to me what dither is, because with my background of what dither is it really does not make sense to what you just said. So please explain to us what dither is, I'm really curious to hear this.

cool..thanks guys..you've ALL been very helpful..eh to red n roll..I didn't mean to offend you or anything..I was just saying I didn't understand what you meant..but uh thanks for all the help guys..

I wasn't offended. I was just too lazy on my first reply to give all the info that I did on my second reply. But I bet you didn't realize how much info was lodged deep within that "8 bit" answer did ya?

The only thing I get offended by is when some moron like beetlefan comes on here and spews nonsense, time and time again to newbies, which only adds confusion. That's why I asked him to explain what "dither" is. He may even take some time now and go read up on how dithering works and realize how it has nothing to do with a "musical spectrum"......and by the way, what is the "musical spectrum?" and what does it have anything to do with a 16 or 24bit recording. There's another term, that has nothing to do with audio. "Musical Spectrum" has to do with the variance of music that an individual is familiar with. He may be trying to refer to "Frequency spectrum"...which also has nothing to do with dither. Anyhow when he does read up on dither, he will come back here and botch it up sooo badly, that we will all enjoy a good laugh at him once again.

So beetlefan....what is "dither"? Come on lay it on us smart guy.

Cheers,

A shave and a hair cut used to be 6 bits, ie, 75 cents. A bit is 12 1/2 cents. Logic then indicates that 8 bits would be one dollar, 16 bits is two dollars and 24 bits is three dollars.

And all this post is just tid BITS of information and soon it will be up to 16 tid bits, which would then make it TOO BITE.
