EmitSound[snd]

emits the sound snd when evaluated.

EmitSound[{snd1,snd2,…}]

emits each of the sounds sndi in sequence.

Details

  • Sounds in EmitSound are represented by Sound objects.
  • Possible values for snd can be any Audio or Sound object as well as any valid sound primitive.

Examples

open all close all

Basic Examples  (3)

Produce a musical note (middle C in piano style):

Wolfram Language code: EmitSound[Sound[SoundNote[]]]

Generate a representation of a sound:

Wolfram Language code: Play[Sin[1000t ^ 2], {t, 0, 1}]

Actually produce the sound:

Wolfram Language code: EmitSound[%]

Emit the sound of an audio object:

Wolfram Language code: EmitSound[Audio["ExampleData/rule30.wav"]]

Scope  (2)

Emit two sounds in sequence:

Wolfram Language code: EmitSound[{Sound[SoundNote[]], Play[Sin[1000t ^ 2], {t, 0, 1}]}]

Create a button that produces a sound when clicked:

Wolfram Language code: Button["play", EmitSound[Sound[SoundNote[]]]]

Neat Examples  (1)

Make a simple DTMF touch-tone dialer:

Wolfram Language code: Flatten[Outer[List, {697, 770, 852}, {1209, 1336, 1477}], 1]
Wolfram Language code: Grid[Partition[MapIndexed[Button[First[#2], EmitSound[Play[Total[Sin[2Pi # t]& /@ #], {t, 0, .1}]]]&, %], 3]]
