Tone

Generate tone. [L=x;][v=y;]%(<on-duration>, <off-duration>, <freq-1> [, freq-2] [, freq-3] [, freq-n] [;loops=x])

• Durations are specified in milliseconds
• Frequencies are specified in Hz

L=x; create x copies of the specified tone stream in memory before playing. Note that L=-1 is not valid, use loops=-1 to loop continuously. Specify L= at the beginning of the tone definition string.

;loops=x Loop x times, use ;loops=-1 for endless loop. This generates the tone, then repeats the generation process so it presumably consumers less cpu and memory than the L= parameter. Note that ;loops=x is postfix notation so it should appear at the end of the tone definition string.

v=y Volume of tones expressed as the equivalent in dB (deciBels) in a PCM waveform. 0 = maximum volume, negative integers represent softer volume (loudness). Do not enter positive values greater than zero! Note that non-linear formats such as G.711 and G.723 will offer slightly lower amplitudes as an artifact of their algorithms.

For example, plays a stutter-like tone 100 times:

{
  "playback": {
    "name": "L=100;%(100,100,350,440)",
    "type": "tone"
    }
}
