    Description
    ReadableSoundBuffer(byte[] pcm, int channels, int sampleRate, int bitsPerSample, PcmFormat.PcmDataType pcmDataType)
    Creates a SoundBuffer with the given pcm data.

    8-bit data is expressed as an unsigned value over the range 0 to 255, 128 being an audio output level of zero .
    16-bit data is expressed as a signed value over the range -32768 to 32767, 0 being an audio output level of zero.
    Stereo data is expressed in an interleaved format, left channel sample followed by the right channel sample.
    The interleaved format also applies to surround sound.
    ReadableSoundBuffer(byte[] pcm, int channels, int sampleRate, int bitsPerSample, PcmFormat.PcmDataType pcmDataType, int blockAlign)
    Creates a SoundBuffer with the given pcm data.
    Consider using ReadableSoundBuffer(byte[], int, int, int, PcmDataType) instead if you're not providing MS_ADPCM data.
    8-bit data is expressed as an unsigned value over the range 0 to 255, 128 being an audio output level of zero .
    16-bit data is expressed as a signed value over the range -32768 to 32767, 0 being an audio output level of zero.
    Stereo data is expressed in an interleaved format, left channel sample followed by the right channel sample.

    ReadableSoundBuffer(ShortBuffer pcm, int channels, int sampleRate, int bitsPerSample, PcmFormat.PcmDataType pcmDataType, int blockAlign)
    Creates a SoundBuffer with the given pcm data.
    8-bit data is expressed as an unsigned value over the range 0 to 255, 128 being an audio output level of zero .
    16-bit data is expressed as a signed value over the range -32768 to 32767, 0 being an audio output level of zero.
