Description
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. A further step would be to create some basic synthesizers / effects incorporating these filters.
Resources to start:
Required Skills
-
Intermediate knowledge of pure data Intermediate knowledge of mathematics (trigonometry, transfer functions, etc) Basic knowledge of Digital Signal Processing theory
Difficulty
For a student with an understanding of the theory behind DSP filters, the project should be fairly easy. For a student without that knowledge, there would need to be an investment of time in learning the theory involved, after which the filter implementation should be quite straight forward.
Possible Breakdown of Steps
-
Research of filter design
-
Implementation of filters in pure data
-
Testing in synthesis and effects patches
