Duration automatically optimizes the unit of the result:

For Audio, dividing the number of samples by the sample rate is equivalent to the duration:

Audio duration can be computed by dividing the number of samples by the sample rate:

The duration of audio files can be imported directly from the file:

Compare with the duration of the imported audio:

Duration returns approximate duration for video files:

Compare with the "Duration" element in Import:

Get exact durations for all tracks using "ExactDurations" element:

Computing "Duration" is typically faster than computing "ExactDurations":
