Announcing [filterview], a new GUI object for generating and visualizing biquad coefficients. It allows to you manipulate the filter band, frequency, and gain using your mouse. The magnatude and phase are then graphed in realtime as the parameters changed, and the list of biquad coefficients are output. It is inspired by the [filtergraph~] object in Max/MSP. Thanks to Mike Moser-Booth for doing all of the math behind the scenes.<br>

It requires Pd-extended 0.43 to run. I just got to a beta state, it works well for me, but it does crash Pd sometimes when you close a patch with [filterview] in it. Try it out and let me know how it works for you.<br>

Also, as a side note, this object is an experiment with a new way of writing GUI objects. It started out as a pure Tcl program, and the GUI part still runs as a standalone Tcl program (try running ./filterview.tcl from the Terminal). This makes development and debugging vastly easier. Additionally, I tried to move more of the GUI code to the Tcl side, so you'll see that it uses fewer widgetbehaviors, and uses Tk's bind feature quite a bit.<br>
