CS_get_signature( ) is called to obtain the
signature that characterizes an audio clip.
sp, /* pointer to an internal data structure */
CS_Signature sig /* signature array */
||Identifies the internal data structure
used for indexing this clip. This structure was created by
a call of
and a pointer to this structure was passed along with each
sample value in successive calls of
||Identifies an array into which this
function will place the signature. The array must be large
enough to receive the 16-byte signature.
A signature may be produced for an audio clip of any duration; however,
for best results, the clip should be at least 0.05 seconds in duration.
The contents of a signature must not be altered by the
application. The meaning of the bytes in a signature is
Signatures acquired using this function may be
compared by calling
CS_compare_signatures( ). A color may
be derived from a signature by calling
This function has no
effect if either the sp
parameter or the sig
parameter is NULL.
