in my expeiance, it was told to me by a chick who worked at a recording studio in nyc (the hit factory-- which is now defunct), that even though most folks only listen to & utilize 16/44.1 (cd quality)- its a good idea to record at the highest possible fidelity, even though the human ear cant typically tell the differance between a recording at its highest fidelity & cd quality- its a good idea to record at the best you can--- because even though you cant do much with that super high quality recording at this time (2012), in the future you may be able to make a differance with that recording. hopefully, editing technology becomes so good that there is a difference in what you can do with it. but-- i also know holding on to a super high quality recording sucks up space on your hard drive.
also, a taper buddy of mine told me that he likes to keep his recordings in evenly numerical dervitives (ie. 16/44.1 or 24/48). yet, im not really sure why. ----he said it happens to do with matching up alternate sources- like, if youre combining sbd/fos/stage lip recordings or alternate mic sources. he said its easier (more effective) to change the way its derived if you keep different sources in even numbers rather than odd numbers when matching/re-deriving it together. honestly, i dont know how much truth there is to this methodolgy. it was just a friends opinion when we tried to match up our different recordings of a show, to come up w/ one consistant recording from both of our recordings, together (he had 16/44.1 & i had 24/48... he said that was better that me doing 24/96 when it came time to derive the two together).
id love to hear others opinions on this matter.
