<p style="color: grey"> Bash recipe 580801 by <a href="/recipes/users/4177147/">Barry Walker</a> (<a href="/recipes/tags/alarm/">alarm</a>, <a href="/recipes/tags/apple/">apple</a>, <a href="/recipes/tags/audio/">audio</a>, <a href="/recipes/tags/baby_alarm/">baby_alarm</a>, <a href="/recipes/tags/cygwin/">cygwin</a>, <a href="/recipes/tags/linux/">linux</a>, <a href="/recipes/tags/noise/">noise</a>, <a href="/recipes/tags/sleep/">sleep</a>, <a href="/recipes/tags/sound/">sound</a>, <a href="/recipes/tags/whitenoise/">whitenoise</a>). </p> <p>This is a simple BASH, DASH and SH script to sooth a newborn baby to sleep for a laptop with a builtin mic. Develeoped around an Apple MacBook Pro.</p> <p>Usage:- [./]shush.sh &lt;time in seconds from 18 to 2700&gt; [sensitivity [Hh|Mm|Ll]]&lt;CR&gt;</p> <p>If time is omitted it defaults to 2 bursts of 9 seconds each and if sensitivity is omitted defaults to [M]edium.</p> <p>It uses Quicktime Player for Apple OSX 10.12.4 minimum /dev/dsp for CygWin and some Linux flavours and arecored for Linux ALSA machines for baby awake detector.</p> <p>Upon the two arguments the white noise generator runs for approximately the time given in $1 in bursts of 9 seconds until the time limit is reached. $2 is used to detect of baby is awake and reruns the noise generator again with a new noise waveform.</p> <p>Enjoy...</p>
