BIOACOUSTIC MONITORING SYSTEMS
FS <WAV,WAC> {OFF,0,1,0+1} <sample rate>
Specifies the file type produced, the source channels used, and the sample
rate for full-spectrum recordings. Channel and sample rate both have AUTO
selections available.
Choose the standard .wav format for recording bats. It consumes less power
and can be opened in any audio software. The .wac file format offers about
a 40% reduction in storage, but at the expense of 40% more power
consumption. Choose WAC for acoustic recordings when storage is more
important than power.
The following sample rates are available on two channels simultaneously
unless otherwise specified:
■
1000
■
2000
■
4000
■
8000
■
9600
■
12000
■
16000
■
19200
■
24000
■
32000
■
48000
■
96000
■
192000
■
256000 (1 channel in WAC mode, up to 2 channels in WAV mode)
■
384000 (one channel)
Choose a sample rate that is at least double the highest frequency to be
recorded.
The
AUTO setting behavior can be seen in the following chart. A sample
rate in the chart indicates that channel will be recorded at that sample rate
(in kHz), a OFF indicates that channel will not be recorded.
