Nope Noise frequency is correct in Hatari 2.0 and in all Hatari version since many years, it was just when rewriting the new cycle exact YM in the devel version that I forgot to take it into account.Steven Seagal wrote:For hi-hats in Hatari, we know it wasn't really the filter but noise frequency.
But even so, Troed confirmed me that hi-hats sounds from 7an were still not correct, which is due to too much filtering.
The filter is very subjective because it depends on the TV/monitor/connection. There is not only one good filter.
I recently could hear the output of my STE on PC speakers through the phono connection: yuck! To be accurate we should emulate all parasites due to bus activity, pixel colour etc.
On my STF connected to a rather good HIFI system I never heard such parasites. Maybe it's STE only (worse isolation ?), or maybe it's your cable ?
Only case when I hear some kind of parasite is if the YM doesn't play any sound and I turn the volume to the max on my old CRT monitor. Then the CRT's speaker can output a small noise that depends on what's on screen, but I think it's more a problem in the SCART cable (not enough isolation between each individual cable, so video RGB signals alter audio signal) than in the ST's output itself.
To record my STF output, I soldered more than 25 years ago a kind of do it yourself "stereo" board ; it's soldered directly on the pins of the 3 voices of the YM and there's really no noticeable parasites.
