Time and Frequency

By default, AL uses seconds and Hertz as units for time and frequency, respectively. A float or integral value of one for a variable that specifies quantities like duration, latency, delay, or any other parameter measured as time, specifies 1 second. For frequency, the basic unit is 1/second, or Hertz. In other words, sample frequencies and frequency cut-offs or filter parameters specifying frequencies are expressed in units of Hertz.
