Final CD and bit/sample rates?

There I heard it! I dug up an old acoustic thing I recorded floating 32 bit, loaded a dither at 8 bit and BAM tons of hiss and noise. 16 bit a lot quieter, 24 bit the noise disappeared into the static of active monitors cranked all the way being fed a moderate level signal.

Okay I'm not deaf :D

Hi Yareek!.....BAM.....there you go bro!!
You're not deaf at all!!
Well done!
 
Besides noise floor, is there a quality difference between 16 and 24?

Because a 16-bit integer can only hold a value from -32768 to 32767.

At 24-bit, those values are doubled.

But what do those numbers represent in a WAV file? Frequency or amplitude?

If it's frequency, then you think the sound would be much more accurate. If it's amplitude, then I guess it just effects the noise floor/headroom? :confused: :confused:
 
Amplitude.

That is significant because every time the signal crosses the zero point (twice per cycle) it goes down through the least significant bits.

Ok.

So what kind of data type stores the frequency? Integer, Long? Float?

I guess this is determined by sample rate?
 
The amplitude of a a wave is constantly changing. The speed that it changes is the frequency.

All I know is when I went down to 8 bit, there was a lot of noise and everything sounded grainy, not terrible, but not clear.

Danny, based on all the info here, there and all around, there is a very perceivable and probably objective difference in quality when amplitude dynamics can be safely increased....ie 8 bit to 24 bit depth.
Though the changes appear less as we climb the bit depth 'ladder', they are still there, regardless (?)....does that work ok? :)
 
Lots of good info everyone, thank you so much. I'm going to start looking more seriously into my options for 24bit . I'd imagine the easiest upgrade is my soundcard but I have other things to weigh,but that's another thread. I'm sure you'll herar from me again.
