Take a blind test - if you can spot 24 bit being better than 16 bit then work with 24 bit samples.
Dont notice any difference myself really.

well, that's not quite fair because you're likely using different samples and what are you monitoring with?

Maybe I do need to set up a blind test and filter a 24bit loop down to 16bit and see if people can differentiate.

Well, this makes sense. When you convert down to 16 bit, dithering is applied. Apperently its artifacts have a pleasing effect on you. A 32 bit sample converted to 16 bits, however, has no more than 16 bits of dynamic depth.

Which raises the question, is it possible to apply "converting artifacts" to 16 bit recordings, to make them sound more pleasing to you, without ever using a 32 bit source....



Note: something similar was going on with wav/mp3 comparisons. In blind tests, a fair amount of people preferred the mp3 sound over the wav. It is not a matter of objective quality, but of subjective enjoyment of certain processing techniques applied to a sound as part of the converting process. Can you apply those techniques on a wav without actually converting to mp3....

I want to say that fuller bass will not be a product of using a higher bitrate, and would really like to hear the samples that you claim show a big difference in the bass between bitrates. Higher bitrates are useful for two main reasons:

1. You are working with very dynamic (wide range of loud parts to soft parts, i.e. not dance music) material, and want the absolute largest range of volumes possible in order to avoid the noise floor becoming an issue.
2. You are working with lots of individual tracks, and want to avoid the noise floor becoming an issue.

All the addition of bits does in audio processing is allow you to represent a larger range of volumes without the noise floor becoming an issue...

[Edit: As Pjotr G says, it's possible the conversion artifacts are actually enjoyable to you as well.]

32bit FTW lol

Remind me tomorow and I'll get them up. I gotta crash for now

No i think someone needs to upload a few loops, each in 16 bit and 24 bit, and then see if you can tell the difference

not again. yes it might sound a little better (headroom? dynamics?) but all the shit u get with it? just dont do it imo. stick with 44,1kHz 16bit beacuse its the standard.

In Bob Katz's book he says that when bouncing down to 44.1/16, working at a higher samplerate makes no audible difference to the final file, but working at a higher bitrate does.

16 bit is nice, but 24 bit will give you smoother reverb and delay decays, among other things. It will sound less "stepped" as it drops from one volume level to the next.

24 bit provides a greater advantage to material with a wide dynamic range - classical music would benefit much more than a hard-hitting trance song.

Originally posted by DjStephenWiley I've actually got a hell of an example of a 16 bit vs. 32 bit track, broken down into mp3, that produces a very noticable difference. The 32bit version has a much richer and fuller bass and is can clearly be distuingished if you have a good monitoring source.

What dithering algorithm was used?
