I have taped a show at 48khz. I am going to share it as 48k, but also going to convert to 44.1k and share, so that people who want to listen on CD can still do so, and I still have my hands on the quality of the work.
Now, which way is better:
A) Convert to 44.1k then cut into tracks
B) Cut into tracks then convert to 44.1k
thanks!

I usually go with option A. ;)
But not because I think it's "better", but because seems to be the easy way.

I don't think either choice matters when you resample and that it only makes a difference if your going post edit like normalize, EQ, etc. Then you would want to edit at higher sample rate and then resample down to 44.1.
-
I re-sample as the last step before burning.
-
if working with 24 bit files you need to resample before you dither.
-
Not working with 24 bit, unfortunately.
I think it makes most sense to convert first, then cut to tracks. Otherwise, I would have sector boundary errors. Can't have that!
-
if 16 bit then you are right there is no reason to track first. even if you want to save a tracked 48k version just make a cue sheet.

If you record at 16/48 do you need to convert to 44.1 or will your cd burning software do it for you? I recorded a show at 16/48 and didn't do anything to it before I burned it to disc (with Nero) and it plays fine. I've uploaded it to the LMA and nobody's complained about not being able to listen to it, so is it necessary to do anything?

some burning software will convert for you
but its better to do it before you burn imo
1 - if you torrent it and the person doesn't have a program to convert they can still burn and not have to mess around
2 - i personally think that a program made to dither can prob do a batter job then one made to burn and just dithers as it goes along (maybe i am wrong)

I agree w/ 1 and 2 but in this thread we are talking about resample not dither but still I would rather use audacity(freeware) for either then a Disc burning program .

The big thing there is that many resampling functions (48k to 44.1k) are not good at all. You want to use the highest possible quality resampler.

Dithering and Resampling is perhaps the most neglected part of our craft. Use the best program you can find to do it right. Generally speaking, a fast handy program is probably not best.
The other issue is that CDs are made of sectors which are about 1/75th of a second each. CDs should be tracked to split evenly on sector boundaries, or else you will have Sector Boundary Errors (SBEs). SBEs will make occasional pops between tracks when you listen to the CDs, and start flamewars from forum snobs who have never pulled a tape, but act like they know more than you do.
Bottom line, convert to 44.1k, then track to avoid SBEs. Use "shntool len" or some equivalent to verify.

If all you need to do is sample rate conversion (and / or dither), R8Brain Free is free and works great.

Not on a pre-intel macintosh it doesn't! >:D
