Default a lil' doubt

Hi all!

I'm about to start a mix with the instruments @ 44/16 and the vocal track @ 48/24

is it technically correct to work with different media formats?

anything I should do at the end of the mix to "equalize" them in terms of media format?

just want to be sure since it's goin to be one shot one kill

thanks for yer help

export individual instrument files @48/24 and go from there.

even tho' they've been rec'ded @ 44/16?

suppose quality doesn't apply here?

could you explain me why?

thanksssss

more bits for your mix plug ins to work on and a uniform sample rate so that your cpu has less sampling/resampling work to do, therefore more cpu power for mix plug ins, etc... depends on intended output format and pc power at your disposal, i s'pose...

Some EQ plug-ins sound better when manipulating high frequencies if you run them at higher sample rates (ReaEQ is an example of constricted HF curves at low sample rates). Many compressors/dynamic processors exhibit a lot of alias distortion when run at low sample rates, and running them at higher sample rates moves the effects of aliasing above the audible frequency range so it becomes a non-issue.

It's not that 48k will intrinsically sound better than 44.1k, it's that any digital processing is likely to sound better (but not necessarily - there are many variables ).

I don't think you need to bother converting the bit-depth. REAPER will already process all audio in 64-bit float regardless of the bit-depth of the source. Also, all your plug-ins will be either 64-bitfp (the Cockos ones) and most others will be 32-bitfp. Some (I think Waves possibly) might process internally at 24-bit, but the point is that your audio bit-depth will already be converted internally.

You should record at 24bit, because you'll have larger dynamic range, but up-converting bit-depth won't increase audio quality in itself (it would just be adding empty bits).
