A simple lowpass filter would be very useful for a lot
of tasks - I'm investigating using one from LAME / GOGO
or another project.

Any comments or suggestions?

    Well, in an ideal world we'd have 1st-4th order filters with
    different Qs (Butterworth, Linkwitz-Riley, Bessel). Even the
    simplest filter would probably require me to go get a DSP
    textbook, so may as well go for broke :)

    Back to reality -- what tasks did you have in mind? There are
    plenty of tools that filter audio already, and scripting doesn't
    strike me as the best way to go about it...

    Just a simple: Lowpass(15600) was what I had in mind -
    nothing fancy, it's just pretty useful for trivial tasks -
    I'm not into building a complete soundprocessor (therefore
    not FFT or other fancy stuff ;)

    A basic implementation has been committed - a better
    implementation should probably be in an external plugin.

    Closing.
