SOUND - QB64Official/qb64 GitHub Wiki

SOUND sets frequency and duration of sounds from the internal PC speaker if the computer has one or the sound card in QB64.

Syntax

SOUND frequency, duration

Description

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.

Error(s)

Low frequency values between 0 and 37 will create an ERROR Codes.
Warning: SOUND may not work when the program is not in focus. Use SOUND 0, 0 at sound procedure start to set focus.
Note: SOUND 0, 0 will not stop previous QB64 sounds like it did in QBasic!
SOUND may have clicks or pauses between the sounds generated. PLAY can be used for musical sounds.
