Hello folks,
I was wondering if there is a noticeable difference in recording at 48 versus
recording at 44.1... For those who do record at 48, is it a noticeable enough
of an improvement to make it worth switching?
Phil replied: 48 does sound a little brighter, in the highs. However, if you
are recording for CD then, you will need a good way to down sample this to
44.1. The best way to do this would be to run 2 PC's. One recording at 44.1
and your other Sonar project at 48. You would then record the output from the
PC running the 48 project to the PC running the 44.1 using analogue outputs in
real-time to a stereo wave file. This would give you the benefit of the nice
highs at 48 however, you wouldn't have to deal with any down sampling at all.
The other way to do this would be to get Sonar to mix down the project for you
from 48 to 44.1 or, get Sonar to mix the project down at 48 then, do the sample
conversion in Sound Forge. I am not personally a great advocate of down
sampling like this, due to the mathematical equations involved. In other
words, when recording for CD, if you wanted to go with a higher sample rate
then, 88.2 would be better as when resampling for 44.1, you are halving the
sample rate. I know a lot of people record at 24 bit 44.1. This is a good
compromised as you get more headroom at 24 bit, plus the audio has more depth,
particularly on instruments such as the kick drum and bass guitar.
Bryan wrote: If you wanted to experiment and record something at 48, besides
changing the sample rate on your audio interface, and going in to the options
menu and audio in sonar, is there anything else you would need to do to make
this switch?
Phil replied: that's all you have to do.
Bryan wrote: also, how would you convert from an existing project that was
recorded at 44.1 to 48?
Phil replied: you wouldn't as up sampling isn't recommended because you can't
add bits that aren't there. Having said that. I suppose you could run the PC
with the 44.1 project using analogue outputs into the PC running 48 and record
a stereo wave file like that. Mind you, probably not much point if you are
going to down sample again for CD.
