Trying to use a convoluted for loop with VLC and Parallel or OpenMPI with no success. Help?
I have about 12,000,000 mod files I'm trying to turn into a test of "unlimited cloud storage" by running them all through VLC and blowing them into mp3 files. I can get this to work serially but when trying to use openMPI or Parallel, something in the syntax is tripping it up some. Here is an example of the command I'm using. Open to any help or suggestions.
Code:
for file in `find ./modarchive/modarchive_2007_official_snapshot_addendum1/ -name "*.mod" -type f`; do parallel -j4 --citation NEWFILE=`echo $file | sed 's/modarchive/mp3archive/'`;echo working on $file; vlc -I dummy -f $file --sout "#transcode{acodec=mp3,ab=128}:standard{mux=mp3,dst=$NEWFILE.mp3,acce~ss=file}" vlc://quit 2> /dev/null ; done

envext
ENVEXT(1) The Canonical Csound Reference ENVEXT(1)NAME
envext - Extracts the envelope of a file to a text file. .
SYNTAX
envext [-flags] soundfile
csound -U envext [-flags] soundfile
INITIALIZATION
soundfile - Name of the input soundfile.
The following flags are available for envext (The default values are stated in parenthesis):
-o fnam Name of output filename (newenv)
-w size (in seconds) of analysis window (0.25)
The envext utility generates a text file containing time and amplitude pairs by finding the absolute peak within each window.
EXAMPLE
Using the command (while in the manual directory):
csound -U envext examples/mary.wav
will produce the a text file containing the following:
0.000 0.000
0.000 0.000
0.250 0.000
0.500 0.000
0.750 0.000

2.761 0.178
3.077 0.011
3.251 0.001
3.500 0.000
Which shows the time for the peak amplitude within each measured window.
