No love for 48 kHz?

Postby Hannes_F » Tue Apr 01, 2014 3:17 pm

Hi there,

I notice that many programs are released in 44.1 kHz and 96 kHz, however not in 48 kHz and wonder why. I happen to work a lot in 48 kHz since that is the film industry standard that many of my clients demand.

What is the general recommendation? Using 44.1 kHz programs upsampled to 48 kHz or 96 kHz downsampled?

I tried to find some information here but the search function will not allow '48' as an entry. So if you have an opinion please share.

Thank you
Hannes

Thanks Antonello, that is one product. I think I have some in 48 kHz from AITB, too.

However, what about the Henry Olonga or the AlexB offerings? I am interested in the question whether there is a specific reason why they spare 48 kHz?

Hi Hannes_F,

If you were looking for more 48khz's
I offer 4 main sample rates, Which are Natively sampled on all my work. So not just on the Silk eq.

I use 48khz most of the time and sometimes 88.2khz, so I created 4 for my own work too

All the best

I use 96 kHz emulation preset to work at 48 kHz. Work at 44. or 88.2 kHz has no sense for me.

I personally can see good reasons to stick to a Native sample rate of 48khz but maybe that's just me.

Here's a good read about this :-)

Lavry argues (very sensibly, in my opinion) that the optimal sample rate would actually be 60kHz. In the real world, 96kHz can be useful, for the reasons mentioned above, but the quad rates are a folly and Lavry refuses to support them! "

Exactly , I didn't have the balls to say it but you just did! high enough to avoid aliasing filter (can cause ringing through band because of filter steepness) but don't go to high to avoid distortions. This could be the reason I prefer 48khz or 88.2khz, The white Paper http://www.lavryengineering.com/pdfs/la ... _audio.pdf

But I must say I am personally generalizing but I think lavry might be saying that it's easier to create converters at those rates? although this could change overtime or maybe has....

hi hannes,

i also work at 48 khz, even for music production.

my experience is, that both 44,1 and 96 khz nebula librarys work well, when up-, or downsampled.
you will have a steep filter with upsampled 44,1 khz programs at 22 khz because of the sampling at the lower rate, but most of the time i don't hear a difference, that bothers me in any way.

for the masterbus, i take some extra care in comparing, when using upsampled programs. but even there, it is often just ok.

downsampling from 96 khz to 48 khz is a little faster, which may be something that is worth to consider in big projects.
when i have to choose between 44,1 and 96 khz (when i have both rates available for a program), i go for 96 khz.

by the way, all my free programs are at 48 khz :D
