soxPlay

Play audio on the speaker via the sound card

• Param soxOption {object} The options in global and input match sox commandline, see man sox

{
  device {string}  Audio hardware device to use. E.g. "hw:1,0"
  driver {string enum}  (Optional) Audio API from OS to use. E.g. "pulse" (PulseAudio), "alsa" (Linux), or "coreaudio" (Mac)
  global {
    ...
  }
  input {   format in which you will write audio data to the writable stream.
    type {string enum} "wav" or "raw" -- "wav" = Wave file (the other input parameters are then unnecessary)
    channels {integer} 1 = mono, 2 = stereo, ...
    bits {integer}  Resolution per sample. 8, 16 (normal), 24 (hifi), or 32
    rate {integer} Sample rate, e.g. 8000 (phone), 16000 (speech), 44100 (CD), 48000 (music quality), 96000 (hifi)
    encoding {string enum} "signed-integer", "unsigned-integer", or "float"
  }
}

• Returns WritableStream Write data to this stream, in the format defined by soxOptions.input

  global {
    ...
  }
  input {   How to record from the sound card
    channels {integer} 1 = mono, 2 = stereo, ...
    bits {integer}  Resolution per sample. 8, 16 (normal), 24 (hifi), or 32
    rate {integer} Sample rate, e.g. 8000 (phone), 16000 (speech), 44100 (CD), 48000 (music quality), 96000 (hifi)
  }
  output {   Which format you want to receive the audio in
    type {string enum} "wav" or "raw"
    encoding {string enum} "signed-integer", "unsigned-integer", or "float"
  }
}

• Returns ReadableStream Contains audio data, in the format defined by soxOptions.input and soxOptions.output
