ConformAudio

ConformAudio[{audio1,audio2,…}]

returns a list of audio objects where all audioi are made to have conforming properties, including duration, data type, and number of channels.

ConformAudio[{audio1,audio2,…},spec]

returns all audio objects of the specified spec.

Details and Options

  • ConformAudio is typically used as a preprocessing step to algorithms that need audio objects that are uniform in some way, such as classification, dimensionality reduction, and assembling into bigger audio objects.
  • Audio specification spec can be one of the following:
  • audiotake the conforming properties from audio
    durationduration given in seconds
    audiotypeaudio type as in AudioType
    {spec1,spec2,…}specification for multiple properties
  • By default, the smallest audiotype that can represent the data stored in all audioi is used.
  • ConformAudio[{audio1,audio2,…}] pads all audio to the duration of the longest audioi.
  • ConformAudio has the same options as Audio with the following additions and changes:
  • AudioOutputDeviceAutomaticdefault audio output device to use for playback
    SampleRateAutomaticsampling rate
    Padding0padding method available in AudioPad
  • By default, SampleRate->Automatic takes the highest sample rate in all audioi.
