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#[, volume#][, panning#][, waveform&]


Description

  • frequency# is any literal or variable value from 37 to 32767, but 0 is allowed for delays.
    • Just like QuickBASIC 4.5 frequencies on or above 20000 produces silence.
  • duration# is any literal or variable number of TIMER ticks with a duration of 1/18th second. 18 = one second.
  • Optional parameter volume# should be between 0.0 (muted) to 1.0 (full volume).
  • Optional parameter panning# should be between -1.0 (hard left) to 1.0 (hard right). 0.0 being center.
  • Optional parameter waveform& can be one of the following:
    • 1 for square waveform
    • 2 for sawtooth waveform
    • 3 for triangle waveform (default)
    • 4 for sine waveform
    • 5 for white noise
    • 10 for a waveform defined by the _WAVE statement (since QB64-PE v4.0.0)
  • More waveform types may be introduced in the future.
  • PLAY can be used for musical sounds.
Note
The last volume, panning and waveform settings will apply to subsequent calls to SOUND (when used without the optional parameters) and PLAY.

Errors

  • Low frequency# values between 0 and 37 will create an Illegal Function call error.
  • Out of range values for volume#, panning# and waveform& will create an Illegal Function call error.
  • All audio related statements and functions work even if the program is not in focus. However, depending on the operating system and environment, this may not always be the case.
  • SOUND may have clicks or pauses between the sounds generated.
Note
SOUND 0, 0 will not stop previous QB64 sounds like it did in QBasic!
