Example 1

Example 1: Encoding To flac, mp3 & aac With Default Settings

From a Windows command shell cd to the directory containing the source wav file directory:

J:\>cd J:\Raw Audio\Dream Theater\Six Degrees Of Inner Turbulence

J:\Raw Audio\Dream Theater\Six Degrees Of Inner Turbulence>dir/b
cover.jpg
dreamtheater_sixdegreesofinnertur_748.jpg
Equipment.txt
info.txt
save.csv
Six Degrees Of Inner Turbulence (Disc 1, Raw).wav
Six Degrees Of Inner Turbulence (Disc 1, Raw).wav.reapeaks
Six Degrees Of Inner Turbulence (Disc 2, Raw).wav
Six Degrees Of Inner Turbulence (Disc 2, Raw).wav.reapeaks
Six Degrees Of Inner Turbulence.RPP
Six Degrees Of Inner Turbulence.RPP-bak
tracklist.csv
Tracklist.xls
WAV

This parent directory should contain the album artwork file, "cover.jpg", and the info.txt file containing the id3 tag information:

J:\Raw Audio\Dream Theater\Six Degrees Of Inner Turbulence>cat info.txt
Artist: The Dream Theater
Album: Six Degrees Of Inner Turbulence
Year: 2001
Genre: Progressive Metal
*
01 The Glass Prison
02 Blind Faith

03 Misunderstood
04 The Great Debate

05 Disappear
06 I. Overture
07 II. About To Crash
08 III. War Inside My Head
09 IV. The Test That Stumped Them All

10 V. Goodnight Kiss
11 VI. Solitary Shell
12 VII. About To Crash (Reprise
13 VIII. Losing Time / Grand Finale

Blank lines in info.txt are ignored. In this example I have used blank lines to deliniate the sides of the double album.

cd to the directory containing the source wave files:

J:\Raw Audio\Dream Theater\Six Degrees Of Inner Turbulence>cd WAV

J:\Raw Audio\Dream Theater\Six Degrees Of Inner Turbulence\WAV>dir/b
01 The Glass Prison.wav
02 Blind Faith.wav
03 Misunderstood.wav

09 IV. The Test That Stumped Them All.wav
10 V. Goodnight Kiss.wav
11 VI. Solitary Shell.wav
12 VII. About To Crash (Reprise.wav
13 VIII. Losing Time _ Grand Finale.wav

The "-h" switch to the encode.pl script will print out the script help:

J:\Raw Audio\Dream Theater\Six Degrees Of Inner Turbulence\WAV>encode.pl -h
encode.pl v6.19 (2016-11-27 Paul Rolan Perkes)

Usage:
        encode.pl [-c n ] [-v n] [*.wav]

Examples (defaults):

        encode.pl

        encode.pl -v 0 *.wav      (default)

        encode.pl -c 128 test.wav

        encode.pl -w -o "../RAW" *.flac

        -S      use standard options: -l -f -m -p
        -V      print version number
        -h      print help {this}
        -o dir  set output directory to dir (default "../MP3/")
        -m      encode wav to mp3
        -c n    lame constant bitrate n
        -v n    lame variable bitrate quality n [0..9] (default 0)
        -f      encode wav to flac
        -F n    set flac compression level to n [0..8] (default 8)
        -z      encode wav to aac
        -Z n    aac average bitrate n (default 320)
        -g      encode wav to ogg vorbis
        -G      set ogg quality [-2..10] (default 8)
        -w      decode flac to wav
        -W      decode mp3 to wav
        -T n    use up to n threads (default 6)
        -C str  use string str for id3 comment tag
        -l      use "Encoded from LP Record by Paul R. Perkes" as id3 comment tag
                and append " [LP]" to album name
        -k      use "Encoded from Cassette Tape by Paul R. Perkes" as id3 comment tag
                and append " [CASS]" to album name
        -B str  use string str for albumartist (TPE2) id3 tag
        -K      tag album as a compilation (TCMP)
        -X      perform verification {flac only, VERY slow}
        -d      debug mode - turn off silent encoding/decoding {verbose}
        -M      debug mode - print out encoding commands
        -t      test mode - don't actually encode/decode
        -a str  append string str to output filenames
        -q      operate silently (quiet)
        -A      extract artist from track name "artist - track name"
        -p      copy mp3's to "D:/My Music/Artist/$tag{Artist}/$tag{Album}/"
        -P dir  copy mp3's to root directory dir (implies -p)
        -R str  use argument str as the artist name for mp3 destination (implies -p)
        -i img  use image file img

        For encodig assumes the existence of:

                ../info.txt
                ../cover.jpg

The following command will encode the wav files to flac, mp3 and aac files with the default encoding settings. The "-l" switch tells the script that the source is from an LP record and that the default LP comment tag should be used and "[LP]" should be added to the album name. I do this to keep track of which mp3's in my library were encoded from LP records and so that there won't be any conflict with digital albums of the same name that were purchased or encoded from CDs.
