Creative Computing – Week 5 – Semester 2, 2008: “FFT (1)”
They're getting less inspiring I know...The difficulty with continuous controlling was still prevalent to a degree this week, but dumping code into a SynthDef seems to provide a solution of sorts. I did check out much of the Nick Collins help files that followed this week’s information, but there is something going on under the hood of those BBC classes that eludes me. It is as if they are technically creating a SynthDef-like environment for themselves in order to operate in a similar manner. I haven’t yet deciphered all the rules governing the use of continuous control arguments to objects outside of a SynthDef and find it is becoming a continuous annoyance.
FFT is not easy, and is made more difficult to control with the introduction of a code based approach. That being said, I have managed to create a simple synth and GUI control system that expands a little on the convolution example presented to us by Mr Haines this week. The expansion has occurred, I begrudgingly admit, in the LFSaw objects that are being convolved with the chosen sound file. I have opted for the controllable creation of a more interesting blend of signals to convolve with the sound file. This idea works well to get sub bass effects out of kick drum samples as the accompanying audio example will demonstrate.
