* SNDSoundStruct - This data format for sound is used as the soundfile
* format, and also the "NeXT sound pasteboard type". It consists of a header
* and two variable length quantities: textual information (the info string)
* and raw data. The raw data starts past the info; the dataLocation is
* normally used to specify an offset from the beginning of the SNDSoundStruct
* structure to this data. The dataSize is the length of the raw data in bytes.
* The dataFormat, samplingRate, and channelCount further describe the data.
* The data itself may be anything; the format determines what the data
* actually means (i.e. sample data, dsp core structure).
* The magic number value may be used to determine the byte order of the data.
* The info string is any null-terminated data that the application may need
* (i.e. copyright information, textual description). The four bytes allocated
* are a minimum; the info string may extend any length beyond the structure.
