SOUND

SOUND produces a sound from the speaker, builds a queue of sounds, and plays a queue of sounds.

Syntax

SOUND frequency!, duration![, volume!][, panPosition!][, waveform&][, waveformParameters!][, voice&]]

SOUND WAIT

SOUND RESUME

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 Hz produce silence.
• duration! is any literal or variable number of TIMER ticks with a duration of 1/18th second (18 = 1 second).
  • A duration of 0 does not produce any sound. However, it can be used to set voice/waveform parameters.
• Optional parameter volume! should be between 0.0 (muted) to 1.0 (full volume).
• Optional parameter panPosition! 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 (default)
  • 2 for sawtooth waveform
  • 3 for triangle waveform
  • 4 for sine waveform
  • 5 for white noise
  • 6 for pink noise
  • 7 for Brownian noise
  • 8 for LFSR-based noise
  • 9 for pulse waveform
  • 10 for a waveform defined by the _WAVE statement
• Optional parameter waveformParameters! can set waveform characteristics based on the current waveform&.
  • waveformParameters! sets the seed when waveform& is 5, 6, or 7.
  • waveformParameters! sets the LFSR clock rate when waveform& is 8.
  • waveformParameters! sets the duty cycle (0.0 to 1.0) when waveform& is 9.
• Optional parameter voice& can be a numeric expression ranging from 0 to 3. It specifies the voice channel that will be used to play the sound.
  • Multi-voice support was inspired by Amiga Basic and Advanced BASIC (for the IBM PCjr and Tandy 1000).
• SOUND WAIT causes all subsequent SOUND statements to be queued.
• SOUND RESUME causes all queued SOUND statements to be processed and sent to the audio device.
  • The latter two commands can be used to synchronize all voices (see the example for _WAVE).
• PLAY can be used for musical sounds.

Note

The last volume, pan position, waveform, and voice settings will apply to subsequent calls to SOUND (when used without the optional parameters) and PLAY. These settings are maintained per voice.

Errors

• Low frequency! values between 0 and 37 will create an Illegal Function call error.
• Out of range values for volume!, panPosition! 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!
