Csound: Stutter Effect

Through the last two Csound blogs about looping lines I have been using the mincer opcode as a means of audio playback. This had been because the mincer can easily use to output of a line opcode to change the pitch and playback speed of an audio sample. The best feature in the mincer opcode, however, is its ability to switch between the function table that is being read at k-rate. By switching quickly between two similar sounds, a new spliced sound can be created. Alternatively, switching between sounds with very different properties or different amplitudes, or by switching quickly to and from an empty table, can create a stuttered sound.

In order to maximise the randomness of the playback I have used a jitter opcode in order to output the read point to the jitter.

I have also randomised the speed with which the mincer switches samples and created controls that change the bounds of the randomised speed.

The full code can be seen here:

Here is an example of the mincer switching between an animal sound, a synthesised energy sound, and silence.

In the next Csound blog I will be discussing the creation of an interactive, modern, 'vehicle braking' sound using both Csound, and the in built effects in Audiokinetic's Wwise.
