If you take two sonically different pieces of audio at different bitrates, and dither them both down to say 16bit, you get two sonically different 16bit pieces of audio and that's the point.
Obviously two different files ar differnet bitrates will be sonically different.
Let's put dithering aside, we're not even getting into that at the moment.
Let's say that you have a 2-track and are using a compressor as a master effect or insert. Now your compressor uses 36 bits
internally. I believe Yamaha's 02r uses 36 bits internal processing if I remember correctly. The D/A converters of the 02r are 20 bit converters (A/D). So even if you are processing at 36 bits internally, your converters are truncating the processing to 20 bit resolution.
Of course a 24 bit file will sound better than a 16 bit file that was recorded at the same system. The dynamics content is pretty obvious to a point. My point was that once you have that 24 bit content the added accuracy with a processor that uses way higher resolution isn't that crucial once you consider the audio is truncated at one point or another. In this case, the converters are the culprit.
Newer TC hardware uses 48 bit internal precission doesn't it? Intneral precission matter, but how much are you getting out of the accuracy of the mathematics if you can't really make use of it? We can't really listen to digital audio. We listen to analog sound that comes from a digital representation. Our limit is still a 24 bit digital wordlength which is then converted to analog, we're not really hearing the 48 bits but what the converters are outputting only, which is 24 bit audio.
I do understand a bit more headroom for 24 bit files but I am skeptic on whether the benefits of very high bitrate effects.
From the last post on Heresy's link:
A crappy 64 bit plugin is going to sound, well, crappy.
We then have to question how efficiently these engines use that extra internal precission and how they represent that precission in the end results.
