This SWI can be used to idenitfy a sample, returning the same information as PlayIt_Open
in auto-detect mode, except that the number of frames is also returned and the operation is passive so doesn't affect the currently playing sample. The data returned in R1-R5 is exactly as if PlayIt_Open
was used so see that SWI for further information. The number in R6 is the same as returned by PlayIt_SampleInfo
(which requires the file to be open).
