N.A.T. Sample Rate Conversion Algorithm

Postby vicdmise » Sat Dec 18, 2010 1:16 pm

Hi -
I'm interested in using N.A.T. to convert some third party programs from 96k to 44.1k but was wondering about the SRC algo. I don't want the bounce to introduce any errors or aliasing. Is N.A.T. algo equivalent to a higher-end src like SOX or R8Brain? If not, any thoughts of introducing something like that?

Thanks

For some reason I trust the conversion done by Nebula itself more. I hope I'm wrong but when I tried to convert with Nat, the results didn't satisfy me.

there are some bugs in the conversion with nat, sometimes it works, sometimes not. i often get programs that are - 6 db lower than the original programs.
sometimes the distort badly on some parameter-settings.

at the the moment, it is the safest way for me, to accept longer loading times and let it be done, when the plugin is loaded by nebula.
this means, that sometimes i open a project and have to wait a few minutes, for all the conversions to take place :lol:

We are debugin NAT SRC, but we are slow. Kernel SRC is not audio SRC. I recommend Nebula relatime SRC up we finish NAT SRC debug.

Thanks Enrique -

Yes, I tried SRC'ing some programs and it didn't work out very well. Some came through well, others actually barely pass audio after the fact. I'm hoping you guys can get it to work, but I'll just wait 'till then.
