Abstract

Two "objects," which run under Max/MSP or Pd, do different kinds of real-time analysis of musical sounds. Fiddle is a monophonic or polyphonic maximum-likelihood pitch detector similar to Rabiner's, which can also be used to obtain a raw list of a signal's sinusoidal components. Bonk does a bounded-Q analysis of an incoming sound to detect onsets of percussion instruments in a way which outperforms the standard envelope following technique. The outputs of both objects appear as Max-style control messages. 1 Tools for real-time audio analysis The new real-time patchable software synthesizers have finally brought audio signal processing out of the ivory tower and into the homes of working computer musicians. Now audio can be placed at the center of real-time computer music production, and MIDI, which for a decade was the backbone of the electronic music studio, can be relegated to its appropriate role as a low-bandwidth I/O solution for keyboards and other input devices. Many other sou...
