sample rate

tazman · 15th February 2007, 07:55 PM

For a project that will eventually go on CD, what is the common wisdom regarding sample rate? 44.1, 88.2, ...? (24 bit)

Thanks,

Rob

44.1

To me it depends on who is doing your mastering. If I am getting my projects mastered elsewhere I give the mastering house the project at the sample rate it was recorded. I will let them take care of the conversion for me before they put it on CD. It depends on your situation if you are doing the final touches on the CD or some one else.

As with everything there are always trade-offs. Many people prefer recording at higher sample rates/bit depths, waiting to converter the finished stereo file to a red book format at the last moment. These people usually beleive there are some sonic advantages to doing this. The trade-off in this case is you will need a better/faster computer and more hard drive space.

I would recommend that you try recording a project at 44.1 and then at 88.2. You can then make up your own mind and do what's best for you.

do a search for "sample rate". you'll be reading for days.

I used to record at 44.1 and then I switched to 88.2 (my machine has enough muscle and drive space for this). The only differnce I did hear was in the cybmals, they sounded a bit more airy, but it could have been just a mnd trick. I am in the process of changing my setup and the new soundcad I bought will do up to 192, but only 8 channels (my old setup had 16 up to 96, and we used 12-14 regularly). I can now go to 16, but using ADAT at 48 max, or 12 at 96max, except that the preamp I have with ADAT (8 channels ) only goes up to 48. So I am trying to figure out if I should thnk about getting another soundcard to add the extra 8 channels at the higher sample rate.

I have always done my own mastering, but in general, what does a mastering engineer require/prefer for sample rate on a mix before the master it (if there is a preference)?

I did and there were so many topics with the words "sample rate". That's why I decided to just post the question...

Thanks,

one theory suggest that you should work on the highest sampling rate that is divisible by the simplest number. if its for CD which is 44.1 then u want to work at 88.2. that way when you downsample the computer will just divide by 2. if u do 96k and downsample to 44.100 then the computer has to divide every second of audio by 2,176.8707 which will create more room for errors.
of course I have (and i doubt someone can) never heard those errors or differences if you downsample from 96>44 or 88>44.

reason u want to work on higher sampling rate is becuase of ALIASING. which is when the computer folds back frequencies higher than 22k to our listening range. thus, creating mud or unclear picture on higher freqs.

you always want to work on the highest bit rate. bits holds the amount of ones and zeros. the higher the stream of bits the more complex mathematical equations can be performed, which means a clearer picture of audio.

and noone can tell the difference between 88/96 and 192/176. if they do, they are dogs!.
