| Music.Sound | Part of Music module |
| Syntax | Music.Sound ( frequency, duration : int )
|
| Description | The Music.Sound statement is used to cause the computer to
sound a note of a given frequency for a given time. The frequency
is in cycles per second (Hertz). The time duration is in milliseconds.
For example, middle A on a piano is 440 Hertz, so
Music.Sound(440, 1000) plays middle A for one second. Sounds are produced synchronously on a per process basis. This means that when a process executes a Music.Sound or Music.Play command, it stops until the command is finished. However, other processes will continue executing.
|
| Example | This program plays a siren sound in the background.
process siren
loop
for i : 100 .. 3000 by 100
Music.Sound ( i, 50 ) % Sound note
end for
for decreasing i : 2900 .. 200 by 100
Music.Sound ( i, 50 ) % Sound note
end for
end loop
end siren
fork siren
… the rest of the program goes here while the siren continues …
