PlaySound Command

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[ <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.
