ICMC 2006 - Friday 10 (Day 5)
Interesting things from ICMC 2006 day 5: Max Matthews (CCRMA) spoke about phase filters The algorithm is a difference equation based on a rotating complex number. A complex number, viewed as a two-dimensional vector, is sometimes called a Phaser, hence the name of the filter. The resulting filter is a high Q two pole resonant filter that is well behaved in terms of stability and is easy to re-tune dynamically during a performance. The filter is about twice as expensive in terms of computer multiplies and additions per sound-wave sample than most other filter algorithms but laptop computers now are so fast that they can run a bank of several hundred Phaser filters in real-time. ...
