AlexB and CDSoundMaster stuff at 88.2khz

Postby Carlsbergen » Thu Feb 03, 2011 7:37 pm

Hi guys.

I was just wondering if there is any problems with using AlexB and CDSoundMaster libraries on 88.2khz files?

For instance, on CDSoundMaster's site it says:
Programs are sampled at 96kHz and are tested to retain accuracy at 44.1kHz and 48kHz sample rates with the latest version of Nebula3 Pro.

No mention of 88.2khz


Just wondering :)

No problem. Nebula should convert programs to your project/session sample rate just fine.

A Nebula chainer could bypass multiple upsampling / downsampling stages when using several programs in series.

yeah!

a nebula chainer would be cool!! upsampling the audio on the input to 96k, downsampling at the output!!

and of course with the ability to safe the channelconfiguration as a preset!!

yeah, yeah, yeah!!! :mrgreen: :mrgreen: :mrgreen:

You can already achieve this with the following Freeware:

This Chainer: http://www.kvraudio.com/db/effectchaine ... ital_media

loaded with nebulas and inserted into this upsampler:

Or this one:

Try it !

SRC in Nebula doesn't affect the incoming audio, it's the programs themselves that are upsampled or downsampled. You need to run your project at the desired sample rate, not just upsample on the way in - if anything I could imagine that causing more problems than it solves. I used Nat to upsample my 44.1k libaries to 96k, the load times are like lightning now. :)

I found this website quite handy for comparisons of src's. thats If you want to change your sample rate on your audio side and not use nebula to up or down sample

http://src.infinitewave.ca/


Some of these src's are free like r8brain and sox


I convert all my audio files to 96khz .

hi tim, you seem to have done this before. can you tell me how it's possible to decrypt the wav files and crypt them again with nat? a short tutorial would be great!

Ah ,

My point was just to convert the audio files with decent src .



I use r8brain free, going up to 96khz.I only use 96khz libarys now.

Alexb told me about r8brain :D

I've just started mixing an album and some of the projects were in 44.1 ,48 and a few in 96.I done some tests with Nebula converting and because I was using a few instances per channel ,I started to hear ( to my ears) that distortion you get from converting, very audible in the high freq.I decided it would be best for me to convert all audio files to 96khz and use 96khz samples in nebula. I was of course listining carefully to the 44.1 to 96 conversion of audio files to make sure they sounded the same(never will be excact).48 to 96 on the other hand is much more easy to sound the same because its only half!

Again the main problem I was having was because of the conversion happening over and over again with many nebula instances per channel.I didnt know about the chainer software though!!

I'm no expert so please chime in. :D

sorry i misunderstood. just wishful tinking i guess because i was wondering if it's possible to convert the nebula presets outside of nebula/nat and bring them back to the nebula format. i'm sure it is but not for us it seems. if there was an easy way to do this all these SRC algo discussions could be brought to an end and everyone could convert their programs with r8brain, sox or alike. best possible quality and no additional loading time. but i guess it's not that easy :mrgreen:
