I found those, but are they really band-limited? I'm fairly sure I hear ugly digital artifacts in the saw.
what artifacts? can you elaborate that a bit more?
Hi, listen at exactly 474 hz, and tell me if you think something sound funny to you, I guess...
ok. i am testing with the rme-card at 44100kHz and good earphones now and i hear it too. i did't look too deep into the problem yet, but as i said, this example is not completely working as it should. also did guenter in his post say something like that this example should be considered as a raw sketcht to show how the algorithm works. i tested again my version with the rme and i can't notice any aliasing. so try rather that one.
note: it was quite interesting for me to see, that cheap cards introduce aliasing, even when playing [osc~]'s. i didn't know about that huge difference before.
