  Returns:

  Encoding used for audio data samples.

• getSampleRate

   int getSampleRate()

  The sampling rate, in samples per second.

  Returns:

  Sampling rate of the audio data.

• getSampleSize

   int getSampleSize()

  The number of bits per sample value per channel.

  Returns:

  Number of bits per sample value in the audio data.

• getChannels

   int getChannels()

  The number of audio channels.

  Returns:

  Number of audio channels.

• getDescription

  @Nullable() String getDescription()

  Returns audio data description.

  Returns:

  Audio data description or null if not set.
