CS_create_sample_processor
The CS_create_sample_processor function allocates and initializes an internal
data structure used in the indexing process.
CS_Sample_Processor CS_create_sample_processor(
CS_Sample_Rate rate /* sample rate */
);
Parameters
- rate
- Specifies the sample rate in number of samples per second (e.g., 44100). This value
must be at least 8000.
Return Values
If the function succeeds, the return value is a valid pointer to an internal data
structure. This pointer may be passed in subsequent calls of
CS_process_sample,
CS_get_signature, and
CS_destroy_sample_processor.
If the function fails, the return value is NULL. The function will fail if the
rate parameter is less than 8000, or if the function is unable to allocate the
data structure.
Remarks
Any sample rate of at least 8000 samples per second may be specified. This
parameter is not limited to common sample rates such as 8000, 11025, 22050, and 44100
samples per second.
This function calls calloc to allocate the data structure, which is about 1024
bytes in size.
