An exception occurs in ScdFile#GetAudio()

[ikafly144]

When calling GetAudio() with an OGG format ScdFile, an "Argument Exception: length is larger than sourceArray" exception occurs in Array.Copy. After checking SaintCoinach's implementation and the SCD format, I confirmed that deleting line 517 (probably) corrects the problem, but I don't really understand how this works.
