24 bit @ 44.1 Vs. 48khz......bigger files or better sound?.....or both :?:
Oh, and are the preamps any good? I'm either going this route, or firepod 10.....just want 24bits

:rr:

The more bits, the better the sound quality, the bigger the files.
The higher the sample rate, the better the sound quality, the bigger the files.

However sample rate and bit depth have different influences on the sound quality:

The more bits, the bigger the difference between maximum signal without clipping and the minimum signal it can record. So, with more bits you have a lot more dynamics.

The higher the sample rate, the higher the frequencies will be that are recorded. Theoretically, the maximum frequency that you can record is half the sample rate. So, CD quality is slightly better than 20 KHz which should be OK for the human ear. However in practice, the response already starts to drop at a fifth of the sample frequency, so CD quality is accurate until about 8 KHz only.

To get a decent sound quality in terms of "human ear specifications" we should record and process at at least 24 bits and 96 KHz. Using these specs, a CD could contain ONE song.

One other thing to consider...if you will eventually drop to cd specs, I've read that any sample rate except 44.1 and 88.2 are not recomended due to complications of the mathmatical equations when reducing...due to this I've only recorded at 44.1 and can't really say one way or the other... I'm merely providing information which is probably meaningless :lol:

Also, 24 bit recording is actually saved as 32 bit (see the manual, page 138, section 7). This means it takes up more room than you think. :)

I say we just go back to 4 track tape recording. How many bits is that?

So, what is stored in the extra bits? It would be silly if they were just empty.

If it is actually stored in 32 bit, and assuming that an empty project is 9,5 Mb (like the G), a one minute one track recording should take 19.5 Mb. On the G, it should take 14.5 Mb and if it is written in 24 bit information it should take 17 Mb. If an empty song on the 1600 is bigger, you should add the difference to every song.

There is no doubt that it's stored as 32 bit. See my "tests" discussed in:
http://forum.dijonstock.com/viewtopic.php?f=10&t=9746&hilit=32+bit

Why it's done that way I have no idea. Definitely wastes hard drive space.

Yes, now I see it I remember it.

You could use Audacity to actually look into the file. I bet it has only 16 million discrete values (2 raised to the power of 24, the number of levels in 24 bit samples) and not 4 billion (2 raised to the power of 32, the number of levels in 32 bit samples).

Strange... why would they do that.
