WaveCRC

WaveCRC (inCRC, waveName [,checkHeader])

The WaveCRC function returns a 32-bit cyclic redundancy check value of the bytes in the named wave starting with inCRC.

Pass 0 for inCRC the first time you call WaveCRC for a particular stream of bytes as represented by the wave data.

Pass the last-returned value from WaveCRC for inCRC if you are creating a CRC value for a given stream of bytes through multiple calls to WaveCRC.

waveName may be a numeric or text wave.

checkHeader is optional. If present, its value determines how much of the wave is checked:

checkHeader	What It Does
0	Check only the wave data (default).
1	Check only the internal binary header.
2	Check both.

Polynomial used is:

x³² + x²⁶ + x²³ + x²² + x¹⁶ + x¹² + x¹¹ + x¹⁰ + x⁸ + x⁷ + x⁵ + x⁴ + x² + x + 1
