Video tutorials on Pure Data (Pd) with Dr. Rafael Hernandez. In this lesson, filtering audio with high-pass, low-pass and band-pass filters.

Pure PD Filters — Pd Community Site - Pure Data

https://puredata.info/dev/summer-of-code/PurePDFilters

Using the rpole~ , rzero~ , cpole~ , czero~ filter primitives provided in the pure pd distribution, create a broader library of filters for use in pure data audio synthesis / processing applications. Filters to be researched and implemented could include: 2, 3 and 4 pole resonant lowpass filters, parameteric eq, formant filters, comb filters, etc.

Filters A filter works by allowing some frequencies through, while reducing or eliminating others. There are three different kinds of basic filters to work with in Pd: the Low Pass Filter, the High Pass Filter and the Band Pass Filter, as well as a Voltage Controlled Filter which can be controlled using some of the LFO techniques we have already looked at.
