'''SOUND''' sets frequency and duration of sounds from the internal PC speaker if the computer has one or the sound card in QB64.
|
||
|
|
||
|
|
||
|
{{PageSyntax}}
|
||
|
:: SOUND ''frequency'', ''duration''
|
||
|
|
||
|
|
||
|
* ''Frequency'' is any literal or variable value from 37 to 32767, but 0 is allowed for delays.
|
||
|
* ''Duration'' is any literal or variable number of [[TIMER]] ticks with a duration of 1/18th second. 18 = one second.
|
||
|
* In '''QB64''' the sound comes from the soundcard and the volume can be adjusted through the OS.
|
||
|
* Low ''frequency'' values between 0 and 37 will create an [[ERROR Codes|Illegal Function call error]].
|
||
|
* '''Warning:''' SOUND may not work when the program is not in focus. Use SOUND 0, 0 at program start to set focus.
|
||
|
* '''Note:''' SOUND may have clicks or pauses between the sounds generated.
