| Usage: | SPF = WFDB_getspf; | |
| Output: | SPF: samples per frame |
Unless the application is operating in WFDB_HIGHRES mode (see section 3.2) and has then opened a multi-frequency record, this function returns 1. For the case of a multi-frequency record being read in high resolution mode, however, WFDB_getspf returns the number of samples per signal per frame (hence WFDB_sampfreq/WFDB_getspf is the number of frames per second).
