Radio Recorder

From Kyle Anderson - Notebook - xKyle.com

The radio recorder is a simple radio recorder that uses a bash script to filter out all the noise and give me daily summaries of the radio chatter.

Hardware

Interface

The interface is simply a directory listing: [1]

Script

#!/bin/bash
while [ 1 ]; do
	OUTFILE=`date +%F-%H-%M-%S`
	echo Recording Audio with noise reduction....
	sox -S -t alsa default -t .wav /tmp/$OUTFILE.1.wav  noisered /etc/channel-noise  &
	PID=$!
	sleep 12h
	kill $PID
	echo Killed... Waiting for write...
	sleep 5s	
	echo removing Scilence....
	sox -S /tmp/$OUTFILE.1.wav -t .ogg /tmp/$OUTFILE.ogg silence -l 1 3000 1% -5 5000 1%
	echo Uploading...
	rsync -aPv /tmp/*.ogg root@a.xkyle.com:/raid/radio-recordings/
	if [ $? -eq 0 ]; then
	echo Upload Done.
	rm /tmp/$OUTFILE.1.wav
	else
	echo Upload not done
	fi
done
