<h3><a name="sound_sample"></a>Sound Frequency Sample</h3>
358+
<ul>
359+
Since sound frequency processing is new to MotionPlus, the following provides an illustrative sample of setting
360+
up the sound and the associated alerts processing. This example will use ALSA. For PulseAudio, MotionPlus uses
361+
the default audio recording device. Although MotionPlus has parameters for the PulseAudio server and device,
362+
the set up is not straight forward and it is just recommended to change the PulseAudio default.
363+
<br>
364+
<br>Go to the command prompt and use <small><code>arecord -l</code></small> to get the
365+
device name such as <small><code>hw:1,0</code></small>
366+
<br>Specify log_level 8 in MotionPlus.conf
367+
<br>Do not specify a log file so that it is console output.
368+
<br>Specify snd_device and snd_show in the sound configuration file such as
369+
<br><small><code>snd_device hw:1,0</code></small>
370+
<br><small><code>snd_show on</code></small>
371+
<br>Start MotionPlus and make a noise to test the output.
372+
<br>Once MotionPlus responds to sounds, press the test button on the device to be monitored.
373+
<br>Note that while the various devices being monitored may be the same, the detected frequency from
374+
each may be slightly different. Care should be taken to not be too precise in the setting of the alert
375+
range for MotionPlus. For example, the frequency may be reported as 3402.2456 and MotionPlus can be
376+
set up to look for that precise number but devices age and the frequency may change. Also, note that the
377+
frequency resolution of MotionPlus is limited by the sample rate and frames from the audio device.
378+
The maximum resolution is determined by the following formula. Sample Rate / (frames * 2). So with the
379+
default sample rate of 44100hz, and frames of 2048, the maximum resolution is appoximately 10.7666hz. This
380+
means that the frequencies detected around the range reported above would be 3413.0122, 3402.2456
381+
or 3391.4790 and no values between.
382+
<br>Once the frequencies of all the devices have been logged, set up the alerts in the sound configuration
383+
file as well as the on_sound_alert and turn off the showing of frequencies. (The frequencies in this sample
384+
are random)
385+
