samplerate

ARCADIOS · Post by **ARCADIOS** » Tue Sep 27, 2005 1:40 pm

scopes manual says that 44.1khz is a general solution good for most applications.
but i would be pleased if i had a detailed answer for which samplerate to use and when?
about scopes synths i know that it is quite different on 44.1 than 48 and 96khz.
but what about effects or other combinations?
i have noticed that when i use a reverb for example in 96khz, on a sound of a music machine, (reason) or on a song taken from cd lets say(wav), i can hear more space distance and clarity than on 48 or 44.1.
is there a general rule for when to use each samplerate, or each case is different?
thanks

If you are ending the process at 44.100 for the CD, I'd stay there from the beginning, it depends a lot from wich algorythm you are using to downsample, but I don't trust them very much.

If you are working for video stuff, pictures etc. the usual standard is 48.000, but if you give them 44.100 they are able to convert.

Higher freq. rates like 96.000 sound very good at the moment, however you loose a lot when you downsample, maybe more than just sticking at 48 or 44, let alone it halves your dsp and cpu power. I never use them.

thanks a lot.
but can you tell me why is there 192khz(not on creamware) for many machines?

some have more money than sense.....
if the final destination is analog or dvd and there is an infinite budget for storage, super high samplerates are a good idea, maybe....

Hi, I have hear a lot of difference in the synthesizers changing from 44100 to 96000. Expecially I noticed a more retailed Hi-end, without (or with less) artifacts in fm-synths and where ringmod is used.

Super audio CD is 192kHz AFAIK so there should be a system to fulfil the request for 192. But as life shows, not always the best specs means standard. Look at Beta, Video2000 and VHS - the last is the worst but won the battle.

Your observations are of course right. But the leap in quallity that one can notice on some synths has to do with the synthesis engine itself, which can copmpute its sounds at a higher sampling rate and thus free of aliasing.

If you want, you could "record" the result at 44.100 Hz and maintain most of the quality improvement.

Other synths are programmed in the way, that they run on a higher internal sampling rate right away from the start (there will be less of a gain by running your projects at a high sampling rate).

Hi kibernaut,
yes, the way a synth is programmed is very important. I usually use the scope synths and my korg Z1. I was referring to the software synths on scope before, modular1 in particular. I've also noticed no differences when recording my Z1 at 44100 or 96000.

Unfortunately since I installed my second board i'm experimenting a couple of things that avoid me to work at 96Khz, (I'm sure this is a problem of optimization of my system, but I haven't got the time to fix it yet) so I can't do some accurate test now.

Usefull quote anyway
