The OROS-culator is a Visual Basic program that calculates the relationships of frequency span and frequency lines of resolution (spectral bins) to the number of samples and length of a time block in spectrum analyzers. It also calculates the file size of digital recordings based on frequency span. The program is based on OROS sound and vibration analyzers but is applicable to many spectrum analyzers.
