SOUND

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.

Template:PageErrors

• Low frequency values between 0 and 37 will create an Illegal Function call error.
• 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.

Example 1: Playing the seven octaves based on the base note DATA * 2 ^ (octave - 1).

Example 2: Playing a song called "Bonnie" with SOUND frequencies.
