Sorry if this suggestion has been made. Don't you think the D->A
used for monitoring is a big factor? (The type of native dsp (digital
sound processing) in one's computer or the external audio card.)
I've experienced huge playback differences between cards and native
dsp with the sort of sounds Lang supplied. Indeed, cheaper CD
players can do an awful job of reproducing such sounds even if the
data on the CD is fine. D-A quality was one of the conclusions
reached when the insect distortion question was explored a couple of
years ago. As to how to get them to play on CD, the only trick I've
found is reducing the dominant Hz's above 8K with sharp eq and
keeping them low in the mix. Something to do with the envelope shape
it seems. Rob D.
