"1- The best resolution you can record at is 16bit/44.1khz .. which for most people is more than adequate .. afterall, that is the standard for CD. Even if your master was 24,000,000bit/96,000,000khz ... it would have to be converted to 16/44.1 when the CDs are made anyway."
If you have access to higher bit rate recording, you should always use it, despite the fact that CD's are 16/44.1. The difference between a project recorded at CD quality - and one recorded at a higher sampling rate, dithered down to 16/44.1 is very big. Processing tracks in the digital domain at 16 bit sounds awfull, like sandpaper. Compound this over all tracks and........
That is also the reason why most good digital consoles have internal floating point processing at bit rates of 30 plus.
Difficult to explain the difference without drawing it. Just think of a wave with 2 lines down through it at equal distance. This would be the points where your audio is sampled. The rest doesn't exist anymore once you have it in a digital format. Lets call this a 16 bit sample. Now consider that, when you "up" the bit rate, every one bit more virtually doubles the sampling rate. Go from 16 to 17 bit and you'll have 4 lines through your wave, four sampling points. From 17 to 18 bit, and you have 16 lines, 19 bit 256. When you get to 24 bit, you'll have millions of lines running through your wave
" 2- If you burn to CDR, it is final. So if you forget to unmute the vocals or something else in a mix ... then you just printed a permanent lame take of the tune to the CDR. I've never used CDRWs, but I think you can only redo the very last track of it (I could be wrong). It's a good option, but the discs are more expensive. I don't use them, so I burn a lot of coasters."
When we are mixing a project we will burn the "days work" on a CDRW, so people can go and listen to it at home, in their cars etc. At the end of the next day we'll just burn the next bit, so overall it works out a helluvalot cheaper than giving them another CD every day. And yes - you can erase whatever you like.
"normal" PC burners are getting better and better. If I copy a disk on my PC - one that is already at 16/44.1 - there is no difference whatever in the quality of that disk or the one on for instance a Masterlink. The main quality difference is in converting A/D and of cause D/A, as well as in clock accuracy. This is a "hot topic" at the moment, as even the hardware provided by the top DAW's, like Pro Tools, have lousy clocks as well as lousy converters, with a very low (106
Db max) dynamic range.
In the end - I think either I'm confused or there is some confusion around (I'm good at confusion!!) All my tracks / mixes are on drives and while we make quick copies on 16/44.1, they stay there until a project's final mix is ready.
After that we do the format conversion, dither down to 16 bit or do a format conversion / data compression for DVD or DVDA
Hope that helps
