Not ATM. I've been thinking of writing a book on acoustics and perception of sound though for about 5 years, which is related to how I know about this sort of stuff. I've also built speakers in my spare time.
I've always been fascinated by sound and how people perceive it. I'm also a classical pianist and guitarist, amongst other things, which may explain it, or be caused by it. Who knows?
It's not something I thought other people would care to read about though, hence never doing it. Maybe time to re-evaluate that.
