Readings:
chapter 2 - 86-114 a useful intro to sound synthesis music
chapter 4 - 134-156 additive synthesis
chapter 6 - 215 262 modulation
chapter 5 - 168- 184 granular
a) using the volume level (get this by looking for a peak in the buffer) from audio input, make a form of interaction. Think about making something subtle, where the volume is controlling some aspect of the scene. Also, see about using left and right volumes, and also, about the rates of change in volume, etc.
b) make a “volume” controlled switch (see for example, claudio’s automatic recording system). Use it to make some interesting work where sound is used as input, but noise is not.
c) use the FFT example, and find sounds which have :
– a very high frequency
– a very specific frequency
– energy in all frequencies
– very low frequencies
record these sounds and include a snapshot of the FFT results
d) use the FFT as input to make a visualizer for audio. think about a meaningful and interesting view of a “specific” piece of music or sound (not just a visualizer for anything). Can you build something that tells a specific story about the audio, or that reveals some unique qualities ?
