What it does
Two-pole recursive filter expo with automatic switching
Demonstrates the range of two-pole filters available in WaveWarp. Two-pole filters are widely used in digital audio owing to their simple and efficient structure. Note that in addition to the default designs, ANY two-pole filter (e.g. designed off-line) can be implemented via the file I/O interface in each Parameter Window.
For fun, a controllable switch driven by a Combo Control Generator is used to automatically toggle the ouput in order to audition each filter design in turn. Note that for efficiency, the Combo Control Generator is running at a factor of 200 times lower than the WAV file's sample rate (hence the need for the 200-up sampler so that all inputs to the switch have the same sample rate, as required by WaveWarp's multirate engine).
