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.
