I know that equation. Smaller market means more margin needed per customer. It still seems high! I don't think it's set right on the price-demand curve for profit maximization. But I could be wrong. It "feels" like it should be $350 max to me, even taking the small market into consideration.
When I look at all the robust and multi-faceted audio software that is out there, $700 seems like a huge stretch for a metering plugin.
Also, I *can't believe* they didn't give you a copy for free. They are using your K-system specs.
I found this site:
http://www.hitsquad.com/smm/win95/SPECTRUM_ANALYZERS/and if that's not enough:
http://www.hitsquad.com/smm/win95/PLUG-INS/The first URL has the Pinguin listed in there, along with a bunch of stuff from other developers. Plugins seem to be this unending world of development (I sometimes get the feeling developers write half of this stuff for fun while eating pizza). There must be somebody who has come up with something like the Pinguin, but has a more reasonable price in mind.
I'm kind of answering my own question here. But I just went to 8thstreetmusic.com and they have the Spectrafoo "basic" version for $299. That one looks good. They also have an ultra version for about $529. I don't understand half the stuff they are talking about in the extra features of the ultra version. The basic one looks good, but it seems it's only Mac TDM/MAS.
