+#!/bin/bash
+
+# Please install 'libav-tools' for Ubuntu 14.04 onwards
+# As ffmpeg is obsolete, it has been replaced by 'avconv'
+# Instead of python script, a simple bash one is sufficient
+
+# A beta release for noNoise-v2
+
+# Usage example
+# $ bash noNoise.sh noisyVideo.mp4 noise-reduction-factor
+							
+# noise-reduction-factor: 0 means no reduction, 1 means 
+# maximum damping of noise (recommended is 0.2 to 0.4)
+
+
+
+# Making a backup of the original video
+echo "Back up original video at  /tmp/orig_$1"
+cp -v $1 /tmp/orig_$1
+
+# Extracting audio from noisyVideo
+avconv -i $1 -f wav -ab 192000 -vn /tmp/noisy.wav
+
+# Creating a noise profile, basically looking for white noise
+# in 0 to 0.5 sec of the clip (change if you like)
+sox /tmp/noisy.wav -n trim 0 0.5  noiseprof myprofile
+
+# Removing noise using noise profile
+sox /tmp/noisy.wav /tmp/noisefree.wav noisered myprofile $2
+
+# Replacing noisyAudio with noisefree audio in original video
+avconv -i $1 -i /tmp/noisefree.wav -c:v copy -c:a aac -strict experimental -map 0:v:0 -map 1:a:0 noisefree_$1.mp4
