Aliasing in Soundfont pitch with KX

marce · Jan 27, 2005, 05:50 PM

Since i readed the "soundfont pitching" thread i search at web a little info about.
I found at MazSound some nice samples to make a comparison between samplers about aliasing.
I donwload the files for do the test here:
http://www.maz-sound.de/main.php?sho...=34&page_id=59

and do the comparison between KXdrivers & Creative Aliasing using Soundfonts. I made the 3 test using a SBLive Full (the first old ones), recording at 48Khz, mono.
The result was that the Creative Drivers are better (appear that not very much) than the KX ones avoiding aliasing problems.
I will upload some .jpg where you can see what im talking. By the moment, if you want compare KX with creative, you can download the test files, and compare the last one (tambourine) with this one

ïn my case, KX makes some aliasing in the last four ascending notes.

I dont know if aliasing quality change from one card to other.

Well, see you, and say me what you think

Usage seems normal here; perhaps it's a fast SRC since it doesn't sound too clean?...
