BeOS audio dev

i have a very simple audio through application that i'll post on the
music-dsp sourcecode page. it just takes an input stream, scales it by the
value of an on-screen fader and then sends it to the mixer. for many simple
apps this is just about all you need - you just have to plug your
processing code in in the middle... with the new beos media kit this has
gotten a bit more complicated, but the way i'm doing it it's all hidden
away in a couple of classes that i took from some be sample code. i haven't
touched those classes in weeks now! give me a couple of days to clean up
the code.

i'm all for sharing this sort of stuff. in case people on the list don't
know it, the music-dsp website has a page with links to a bunch of source
code for a number of different platforms. the url is at the bottom of this

music-dsp mailing list web site:

According to one lady engineer, people tend to recognise shapes of
others in bunny suits and it's hard to recognise co-workers outside
of the clean room, unless you just look at their eyes.
