The Sound Extension lets NetLogo models make two kinds of sounds: MIDI sounds and playback of pre-recorded sound files.
The Java APIs used are javax.sound.midi and java.applet.AudioClip.
The sound extension comes preinstalled. To use the extension in your model, add this at the top of your Code tab:
extensions [sound]
If your model already uses other extensions, then it already has an
extensions line in it, so just add sound to the list.
For more information on using NetLogo extensions, see the Extensions Guide
For examples that use the sound extension, see the Sound section under Code Examples in the NetLogo Models Library.
The MIDI part of the extension simulates a 128-key electronic keyboard with 47 drums and 128 melodic instruments, as provided by General MIDI Level 1 specification.
It supports 15 polyphonic instrument channels and a single percussion channel. Using more than 15 different melodic instruments simultaneously in a model will cause some sounds to be lost or cut off.
The pitch of a melodic instrument is specified by a key number. The keys on the keyboard are numbered consecutively from 0 to 127, where 0 is the left-most key. Middle C is key number 60.
The loudness of an instrument is specified by a velocity, which represents the force with which the keyboard key is depressed. Velocity ranges from 0 to 127, where 64 is the standard velocity. A higher velocity results in a louder sound.
Reports a list of the names of the 128 instruments
for use with sound:play-note, sound:play-note-later,
sound:start-note and sound:stop-note.
Plays a drum.
Example:
sound:play-drum "ACOUSTIC SNARE" 64
Plays a note for a specified duration, in seconds. The agent does not wait for the note to finish before continuing to next command.
;; play a trumpet at middle C for two seconds
sound:play-note "TRUMPET" 60 64 2
Waits for the specified delay before playing the note for a specified duration, in seconds. The agent does not wait for the note to finish before continuing to next command.
Example:
;; in one second, play a trumpet at middle C for two seconds
sound:play-note-later 1 "TRUMPET" 60 64 2
