Could somebody describe me what's happening when i play this file? I'm trying to add 2 high frequency Cycle~ signals...

There are 2 HighFreq -6dB signals there (above the average hearing limits)... sometimes one is played alone sometimes the other... all good, can't hear anything...

But when the 2 signals are added, then there is some digial artifact i can hear on a lower frequency... What is strange as i can't see that on a spectrum analizer...

Do you hear that artifact too? Any ideas how to get rid of it?

Not so much a digital artifact as simple physics. .

Might also have something to do with aliasing.

[cycle~] is not alias-free. At least it used to be, back in the days...

But wait...if it was aliasing it should show up in the spectrum analyzer, right?

yeah, i was thinking maybe it can be some kind of harmonic distrotion on the D/A converter?

btw, do you hear any sounds if you check the file?

I'm hearing high pitched (>2khz) chirp like bursts.

If you substract the frequencies of the two cycles~ and compare it to the frequency you hear you can tell if it is the difference tone.

Because of the chirp like sound i suspected aliasing

Using a really cheap onboard sound card.

Could also be a combination of d/a artifacts, aliasing, difference tones and the harmonic distortion of your ear ;)
