I downloaded the http://src.infinitewave.ca/TestSignals.zip , following their instructions (SRC Comparisons - FAQ) to perform the SRC test for some audio softwares I own: downsampling an audio clip from 96kHz to 44.1kHz. When I do the test on Cubase 9.5.0, the only visible difference on the spectrum (comparing to Wavelab 9.5) is that the built-in SRC of Cubase 9.5.0 does not high-cut the signal frequencies higher than the target sample rate, leaving these useless frequencies to become unwanted noises in the target converted file.
Please carefully check the attached screenshots. Cubase needs to get this issue solved.
P.S.: I don’t post irrelevant results from other products here, but Kontakt’s built-in SRC behaves extremely terrible. I have sent all my test results to the website I mentioned above and they may post my results on their website in the next few days.
P.P.S.: I hope that the fix to this issue won’t be postponed to Cubase Pro X (ten).
That’s not what the lack of filtering (high cut) looks like. The resulting audio would become completely unusable if there was no filtering. If you listen to the file converted by Cubase, you’ll notice that the aliasing is basically inaudible.
You probably get more aliasing from playing 48kHz Kontakt libraries in a 44.1kHz project, which a ton of people do.
I’m not saying that Cubase’s SRC couldn’t be improved, but this isn’t the big deal people make it out to be either.
