Mostly intrested in audio stuff, some math intrests too. But I don't often make huge contributions. Mostly I help out by reverting vandalism, voting on vfd's, sometimes a little cleanup.

I don't have too many, most of my time is spent over on vfd or making minor edits. But I have some stuff planned to write and I want to start working on the cleanup page some more, so this will get bigger.

• Pulse-density modulation

• Continuity (Rewrote, merging in info from continuity error)

${\displaystyle \int _{0}^{1}{\frac {x^{b}-x^{a}}{\ln x}}dx}$

${\displaystyle {\frac {1}{2}}\int _{-\pi /2}^{\pi /2}\left({\frac {9}{9+5\cos \theta }}\right)^{2}d\theta }$
