Miscellaneous unix scripts.

## Perl Scripts

Scripts for processing mp3 files including id3 tags.

### cdda_TO_mp3.plx    [working-dir [output-file-prefix [first [last]]]] 

     where:

        working-dir            working directory for *.ogg, *.mp3

        output-file-prefix     prefix-tt.ogg and prefix-tt.mp3 files are created

        first                  first track to process

        last                   last track to process

> rip cdda audio tracks,

> encode each track into ogg wrapped flac file,

> normalize the pcm data and

> encode track into an mp3 audio file

 

### csv2txt.plx    [output-file-prefix [working-dir ]]

 

>generate 1 text file per record

>from a comma separated values database file

### MP3_TO_DISCnn.plx    -m min -i in-dir -o out-dir

  

     where:

        -m, --min         number of minutes to split input-files into

        -i, --in-dir      input directory

        -o, --out-dir     mp3 output directory

        -n, --normalize   normalize the amplitude of each mp3 file

        -v, --verbose     verbose excution

        -h, --help

        in-dir             mp3 input file

        out-dir            working directory for *.mp3

 >processes a directory of *.mp3 audio files, spliting each large mp3 file into min size files and moves them to dirnn

 >rename to nn-01.mp3, nn-02.mp3, ...

 >create and move to directories discnn/nn-01.mp3, discnn/nn-02.mp3, ...

### sndtrk.plx    working-dir

 

     where:

        -i, --input-dir   input-dir          input directory for video files (*.mp4, *.m4v)

        -w, --wrk-dir     work-dir           work directory for extracted soundtrack files (*.mp3)

        -v, --verbose                        verbose excution

        -h, --help          

> extract soundtrack from each file (*.mp4, *.m4v) into named pipe,

> normalize the pcm data and

> encode file into an mp3 audio file

### sparsecopy.plx    [source-dir [target-dir [ext ]]]]

 

     where:

        -s, --source       source-dir            source directory

        -t, --target       target-dir            target directory

        -e, --ext          ext                   extension of files to copy

        -f, --force        overwrite all existing targets

        -u, --update       update old target with newer source file

        -i, --interactive  prompt whether to overwrite target file

        -v, --verbose      verbose execution

        -h, --help          

> create target directory tree

> copy files with extension ext into target directory tree

### txt2id3.plx    infile [output-file-prefix [disc number]]

> generate 1 text file per record
