The playback time, in seconds, can be set using the
playback the rst 5 seconds of a le use:
naplay -t 5 file
Note that the option can not be used with the

results in 30 seconds of playback consisting of the rst 10 seconds of the le repeated
3 times. Note that there will be no space between the repetitions.

5.7 Sampling Rates

There are two sampling rates of importance in playing back a le; the rate at which
samples are sent to the DAT machine, and the sampling rate of the le that is to
be played back.

5.7.1 DAT Sampling Rate

Digital audio equipment usually accepts three possible sampling rates: 32,000,
44,100, or 48,000 samples/second. The most common rate is 48,000 samples/second
and this is the default for the
compact disks or pre-recorded tapes.
The digital audio sampling rate can be changed using the
playback a le such that the DAT records it at 44,100 samples/second use:
naplay -S 44100 file
Note that it is assumed that the le being sent to the DAT is sampled at the
same rate as chosen with the
-r
option. The number of repetitions is given as the
-R
program. The 44,100 is usually only used for
naplay
