thanks Spirit, now I know how aliasing sounds!
I want my Kurzweil K2500/RS win this test, may be I'm gonne make this test!

hubird, glad you now know how it sounds
Weird, how you never noticed it... finally you can compare how aliasing is different on your keyboard playing synths at 44.1 or 96kHz.
Notice especially when playing the highest notes.
Recently someone posted a link with an example everyone knows: watching TV, if you see a car's wheels, if the wheel spins at 24 rounds per second and video feed is at 25fps, the wheels will look as if they'd turn in reverse. Same happens to audio, when digital synthesis wants to make a frequency above niquist, they will be folded back in the audible spectrum. As samplerate increases, so will niquist, and these artefacts will move to higher/unaudible frequencies.
ps. synthesis is /much/ more sensitive to aliasing than sampling.

Contact Simon V. He's typically responsive and if you provide newer results I'm sure he'll post them up.

it was originally posted even earlier, > than half a year or so back, but my mem fails, too
cheers, tom
btw it's a bs test setup of zero practical relevance - a tambourine transposed 8 tones up and down
if you optimize to some nonsense like that you can yield some great benchmarks...
