Wow. How hard can this be? Surely it's just like image scaling, but

If anyone want's to put me right...
After a discussion
with a friend, I´m not so sure anymore. He is recording his album at
44.1 kHz, arguing that this will avoid downsampling when finally
pressing a CD. So, are there any opinions about this?
The quality of the dithering algorithms can make very a noticeable
difference in your final product if you have to down-sample - but that
doesn't necessarily mean that you're relegated to life at 44.1.
IMO, the best solution is to work at 88.2khz whenever possible. This
way, you can down-sample to CD quality without quantization errors. I'm
no DSP guru - but as I understand it, sampling at a multiple of 44.1
(88.2, 176.4, etc.) is the cleanest way to go outside of DSD.
FWIW - I haven't heard a software dither (with quantization) that I
thought was decent - FOSS or otherwise. The best down-sampling I ever
heard came out of a $3,500 Apogee box. Hope this helps,
Greg
