I tried it out.. turns out that you included a stray .depend file.. so you will need to make depend first before it will build, once you do that it will stop complaining about /usr/local/include/AF/... or something... it does look nice.. the only complaint that I have is that there are 5 max peaks at 8k, 4 more at 16k, and then some other smaller ones when increased to 22k and 32k... any idea on those? they exist even when the mic is off.. so I'm thinking it's math errors.. this is VERY kool though.. I like the waterfall mode... ttyl.. -- John-Mark Gurney Modem/FAX: +1 541 683 6954 Cu Networking Live in Peace, destroy Micro$oft, support free software, run FreeBSD
