• some history

  • Xenakis / Stockhousen / etc.
  • Max Mathews (Bell Labs) / Music-N
  • Csound
  • Max / PD
  • PD
  • ChucK
  • SuperCollider
  • Overtone

• UGens (Unit Generators) / opcodes

  • typically written in C or C++

• type system

  • what I had before
  • common fields
  • subtyping

• features

• efficiency

• applications

  • live coding
    • meta-ex - "Our sound isn't hardcore, breakcore or speedcore - it's multi-core and fully hyper-threaded."
  • electronic music
  • DSP research
  • game audio (sound engine)

• some current nodes

  • SinOsc
  • Gain

• File IO

  • reading
  • writing

• operator overloading

  • +, *

• main methods

  • play
  • stop
  • af_open

• challenges

  • Garbage Collection!

• Future Work

  • More Nodes! (bandlimited oscillators, filters, etc.)
  • lower latency
  • multi-channel
  • easier install (port shim.c to pure julia)
  • music thoeory library (notes, chords, intervals)
  • sequencing abstractions
  • better error handling (audio task shouldn't crash)
  • common utility functions (table lookup, interpolation)

• optimization lessons

  • mathconsts allocate!
  • watch out for type conversions
  • really watch out for globals
  • @allocated gives different results than @time?
