# This code uses some features from the pre-release of Sonic Pi,
# due out later this month (touch wood!).

# If you just can't wait for the release but want to try it yourself
# you can either build the Sonic Pi master branch from source (pros: free, cons: hard)
# or share some love and contribute to the Patreon page to support Sonic Pi's development
# https://www.patreon.com/samaaron
# That will give to access to the latest pre-release versions

Cymbal synthesis tutorial

Dan Stowell



This tutorial describes an approach to synthesising decent-sounding cymbals, in a way that is efficient enough for a real-time synthesis system.

Prototype of vocoder on Sonic Pi

Demo here: https://www.dropbox.com/s/qiktze3ml7bz5iq/autotune_the_shipping_forecast.wav?dl=0 Original voice input here: https://soundcloud.com/jb_uk/neil-nunes-bbc-radio-4-and

This is a demo of a simple effects synth using the Vocoder.ar UGen from SuperCollider. This is a fairly primitive vocoder implementation made of a bunch of bandpass filters which are "tuned" to various frequencies.

The results are mixed, but it's difficult to get a decent reproduction of the words from this.

To get T-Pain/Imogen Heap style auto-tune it would be necessary to write a different algorithm probably using a technique called PSOLA which is described at the following links:
