Just for the sake of completeness and for those new to the topic, here are some mainstream audio programming languages people might also want to take look at:

- Csound This is one of the first ones, a little bit dated now but there is ton of material and nice books

- Pure Data (max/msp) Graphical audio language, also popular and very nice for beginners

- Supercollider Object oriented platform for audio synthesis (smalltalk)

- Overtone Functional audio synthesis platform using Clojure (totally awesome)
