- PlaySound[ <Note>, <Duration>, <Instrument> ]
- Plays a MIDI note.
- Note is an integer from 0 to 127 that represents a musical note given by the table below. When note = 60 a Middle C is played.
- Duration is the time to play the note in seconds.
- Instrument is an integer that represents the synthesized instrument used to play the note. See technical specifications for possible instruments.
- Most instruments are supported, but there are differences between computer platforms.

- PlaySound[ <JFugue Note Sequence>, <Instrument> ]
- This command is deprecated and will be removed from GeoGebra soon
- PlaySound[ <URL> ]
- Plays a MIDI (*.mid) or MP3 (.mp3) file
- e.g. PlaySound["http://archive.geogebra.org/static/welcome_to_geogebra.mp3"]
- PlaySound[ <Function>, <Min Value>, <Max Value> ]
- Plays a sound generated by Function, a time-valued function with range [-1,1]. The time units are seconds and the sound is played from time Min Value to Max Value. Sound is generated by 8-bit samples taken at a rate of 8000 samples per second.
Example:
PlaySound[sin(440 2Pi x), 0, 1]
- This plays a pure sine wave tone at 440 Hz (musical note A) for one second.
- PlaySound[ <Function>, <Min Value>, <Max Value>, <Sample Rate>, <Sample Depth> ]
- Plays a sound generated by Function, a time-valued function with range [-1,1]. The time units are seconds and the sound is played from time Min Value to Max Value. The sampling method is specified by "Sample Depth" and "Sample Rate".
- "Sample Rate" is the number of sample function values taken each second. Allowable values are 8000, 11025, 16000, 22050, or 44100
- "Sample Depth" is the data size of a sample in bits. Allowable values are 8 and 16.
- PlaySound[ <Boolean Play> ]
- Pause or resume play.
- PlaySound[true] = play, PlaySound[false] = pause.
