Media_CreateSound allows you to create a tone, or white noise, or silence for a specified duration.

Parameter Description
type created sound waveform type. One of the following:

  • sine
  • square
  • sawtooth
  • silence
  • noise
  • sin (same as sine)
  • saw (same as triangle)
  • rectangle (same as square)
  • none (same as silence)
duration Created sound duration in seconds.
frequencyOrNote Created sound wave frequency in Hz or note name and octave.
parameters Optional parameter. Hexadecimal convert settings.

The function returns a sound to a container field.

Sine, square, and sawtooth types can give you precise tones on the musical scale, as well as various beeps and buzzes, depending on the frequency setting you use.

Silence simply creates an empty sound result for the specified duration.

Noise creates a static-like white noise for the length of time you want.
