sample rate conversion quality issues

Alex,

The original poster asked if a 24 bit recording converted to 44.1 with good software would sound worse than the same recording originally mastered at 16/44. If we can agree that "good" software means there won't be any truncating or artifacts introduced by the downsampling, I fail to see how the downsampled recording would not be superior in resolution to the one mastered at 16/44. In my experience, even recordings made at 16/48 and dithered to 16/44 with good gear sound (slighter) better than those mastered at 16/44.

Not that easy, Paul. It really depends on the equipment (algorythms) used during any type of conversion. With inferior equipment all benefits of recording with higher resolution would not just be lost, but the resulting 16/44 would be actually worse that if it was initially recorded this way.
I did many tests using my dCS gear as a playground and as of now my solution is - try to stay in one resolution.
There are many sides to it, but in general - less conversion is better.

Continuing Phild's comment, I've heard that if you plan to drop a digital recording to 44K that it's best to record at a sample rate that is an even multiple of 44K. So in that case, recording at 44K or 88K would be better than 48K or 96K. Logically it makes sense to me as converting from 48K to 44K would require much more calculations and therefore more chances for errors.

Yeah, what Paul said. There are some people who think it's better to record at 44.1 (if that is the final destination) and skip the conversion. I haven't compared the two. You might want to try both and see if you hear a difference.

FYI - You can not record to a DAT @ 24 bit. Only 16 bit @ 44.1 or 48.0 kHz......

Regarding your other question -> you will get the best resolution when you record at the highest rez rates possible. A recording made at 24 bit/44.1 khz (and then downsampled to 16 bit/44.1 for playback) should sound noticeably better than a recording made at 16 bit/44.1 khz. However, you want to make sure that you are using good digital conversion software (or hardware) that does not introduce artifacts when downsampling. Also, make sure that your software/hardware dithers to 16 bit and does not truncate the data when converting to 16 bit.
