  • 44.1 Khz or 48 Khz?

    Hi I can't find it anywhere on this site, but am I correct that Vienna is recorded at 44.1Khz? If all I am using is Vienna and Altiverb, is there any point in setting my DAW to 48 Khz? Will this produce a better quality of sound? My tracks are going to video, which I think run at 48Khz? Was just wondering what difference going up to 48 Khz would make? Thanks, Simon

  • Hi Simsy Running a session using Vienna Instruments at 48k will not sound any better, if anything it will sound inferior, as there is an additional process involved sample rate converting the original samples (44.1k) to a different sample rate (48k) However in your circumstances it is not so straight forward as it sounds like the ultimate destination format will be 48k. The thing to consider here is that if you run your session at 48k, yes sample rate conversion is happenning at an earlier stage of the Vienna instruments but, and this may make the difference, any additional audio you may be working with (if it's video orientated stuff) can potentialy remain native sample rate and all the processing and fx you add will be carried out at your end master sample rate so will not have to be converted. Can I suggest you set up a simple session using Vienna Instruments run it at 48k, do a mix then without changing any other settings change the session sample rate over to 44.1K run the same mix, sample rate convert it to 48k using the sample rate convertor you would use for your project work then compare the 2 mixes. If you cannot tell the difference then I suggest running your sessions at 44.1 will be less CPU intensive. If you can tell the difference use the process that provides the best sounding mix! Hope this gives you some ideas. Julian PS I thnk I saw somewhere that the Vienna recordings are all made at 44.1k and 96k in parallel but it is the 44.1k files that currently make up the present comercially available library.

  • To Simsy: It won't do any harm to the sound of your VIs if you work at 48 kHz, but you won't gain any benefits form it either (with the exception of some other plugins like EQs that will produce a marginally better sound at higher sampling rates).

    To Julian: All our samples are recorded at 24 bit / 96 kHz and stored in 32 bit FP-format throughout the whole editing-process. Sample-rate conversion takes place just before mapping, using an algorithm developed in-house, optimized for the use with single notes of acoustic instruments.

  • I work in 44.1 / 32 float (Cubase 4) and convert at last stage on final mix as I deliver production to Director.  I haven't been able to tell any discernible advantage doing it this way.

    Others opinions using C4?

    --One question I have for anyone is that I deliver the final mix in 48K/24 bit (usually AIFF) 'undithered'.  Should this file be dithered to 24 bit (from the 32 bit float)?  In other words as final dub is done is the music track (s) dithered in the production (to 16 bit)?

  • Hi Rob, Thanks for the advice! Dietz, I say I run vienna on a 48 Khz project, will they then sound better because the EQ, Limiters and Reverb are running at 48 Khz?

  • The keyword was "marginally" ;-). The samples themselves won't benefit at all, though.

    Best,

  • Just to throw m my thoughts--I've been working with video for years and this maybe a little outdated info--but working in 48k is much safer when dealing with video.  You might end up with sync problems down the road.  48k holds sync much better.
