NAME

       pacpl - Perl Audio Converter, a multi purpose converter/ripper/tagger

SYNOPSIS

       pacpl --to <format> <options> [file(s)/directory(s)]

DESCRIPTION

       Perl Audio Converter

       A Linux CLI tool for converting multiple audio types from one format to another.

       It supports the following audio formats:

       ========================================

       3G2, 3GP, 8SVX, AAC, AC3, ADTS, AIFF, AL, AMB, AMR, APE, AU, AVR, BONK, CAF, CDR, CVU,
       DAT, DTS, DVMS, F32, F64, FAP, FLA, FLAC, FSSD, GSRT, HCOM, IMA, IRCAM, LA, MAT, MAUD,
       MAT4, MAT5, M4A, MP2, MP3, MP4, MPC, MPP, NIST, OFF, OFR, OFS, OPUS, OGA, OGG, PAF, PRC,
       PVF, RA, RAM, RAW, RF64, SD2, SF, SHN, SMP, SND, SOU, SPX, SRN, TAK, TTA, TXW, VOC, VMS,
       VQF, W64, WAV, WMA, and WV.

       It can also extract audio from the following video extensions:

       ==============================================================

       RM, RV, ASF, DivX, MPG, MKV, MPEG, AVI, MOV, OGM, OGV, QT, VCD, SVCD, M4V, NSV, NUV, PSP,
       SMK, VOB, FLV, WEBM and WMV.

       Parallel Processing, a CD ripping function with CDDB support, batch conversion, tag
       preservation for most supported formats, independent tag reading & writing, service menus
       for KDE Dolphin/Konqueror, GNOME Nautilus script, and action scripts for Nemo/Thunar are
       also provided.

OPTIONS

-t, --to format

set encode format for the input file(s) or directory(ies). you can see a complete list of
supported encode formats by using the --formats option.

-r, --recursive

recursively scan and convert input folder(s) to destination format.

-p, --preserve

when recursively converting a directory, preserve the input folders directory structure in
the specified output directory. such as:

pacpl --to ogg -r -p /home/mp3s --outdir /home/oggs

in the example above, let's assume the directory structure was:

/home/mp3s/Alternative
/home/mp3s/Alternative/New
/home/mp3s/Rap
/home/mp3s/Country
/home/mp3s/Techno/

the output directory will now contain:

/home/oggs/Alternative
/home/oggs/Alternative/New
/home/oggs/Rap
/home/oggs/Country
/home/oggs/Techno

with all files in each sub-folder converted to ogg.

-o, --only format

only convert files matching extension. this option is useful when you have a directory or
batch of files with mixed audio types and only need to convert one specific type.

-k, --keep

do not re-encode files with extensions matching the destination extension. instead...copy
them to the output folder, or skip to the next file.

-j, --jobs

number of simultanious jobs to run at once. the default limit is set to 4 in pacpl.conf.
You can modify this value on the fly using --jobs=<num> or set it perminately in the
configuration file

-f, --formats show a list of supported encode/decode formats.
-h, --help show the short help menu.
-l, --longhelp display the complete list of options.
--version show version and licensing information.

USER OPTIONS

--defopts 1/0

to turn off default encoder options use --defopts 0. this option gives you more control
when using the --eopts command.

defopts is set to 1 by default. you can also toggle this option in /etc/pacpl/pacpl.conf.

--eopts options

this option allows you to use encoder options not implemented by pacpl. an example would
be:

pacpl --to mp4 --eopts="-c 44100 -I 1,2" YourFile.mp3

--dopts options

this option allows you to use decoder options not implemented by pacpl. an example would
be:

pacpl --to mpc --dopts="--start 60" YourFile.ogg

--outfile name

set the output file name to name.

--outdir directory

place all encoded files in directory.

--dryrun

show what would be done without actually converting anything. this is a good way to
trouble shoot, or to see what would be done without actually touching your files.

--overwrite

replace the output file if it already exists.

--normalize

adjusts volume levels of audio files.

--nopts options

this allows you to specify normalize options not implemented by pacpl

--delete

remove source/input file after the conversion process has finished.

--encoder encoder

specify an alternate encoder for the selected output file(s)

you can see a list of supported encoders by using the following:

pacpl --encoder format

--decoder decoder

specify an alternate decoder for the selected input file(s)

you can see a list of supported decoders by using the following:

pacpl --decoder format

-v, --verbose

show detailed information about the encoding process and what's actually being done.

ENCODER OPTIONS

--bitrate num

set the bitrate to num. default is 128. this option does not apply to all formats.

--freq num

set the frequency to num. default is 44100. this option does not apply to all formats.

--channels num

set the number of audio channels in the output file to num. this option does not apply to
all formats.

--effect str

see sox(1). this option only applies to the following:

AIFF, AU, SND, RAW, VOC, SMP, AVR, and CDR

--fcomp num

set flac compression level to num. fastest -0, highest -8, default -2

1 = fast
2 = simple
3 = medium (default)
4 = high
5 = extra high,

--acomp num

set ape compression level to num.

1000 = fast
2000 = normal
3000 = high (default)
4000 = extra high
5000 = insane

--oggqual num

set ogg quality level to num. -1, very low and 10 very high, default 3

--spxqual num

set speex quality level to num. 0-10, default 8 (use --bitrate <num> when using
ffmpeg/avconv as encoder)

--aacqual num

set aac, mp4, m4a, or m4b quality level to num. default 300

--mpcqual str

set mpc/mpp quality level to str.

thumb low quality/internet, (typ. 58... 86 kbps)
radio medium (MP3) quality, (typ. 112...152 kbps - default)
standard high quality (dflt), (typ. 142...184 kbps)
xtreme extreme high quality, (typ. 168...212 kbps)

--ofmode str

set off/ofr/ofs compression mode to str. normal, extra, and extranew modes are
recommended for general use. available options are:

fast
normal (default)
high
extra
best
highnew
extranew
bestnew

--ofopt str

set off/ofr/ofs optimization level to str.

specify the optimization level in the engine. In order to achieve optimal compression at
all sample types, sample rates, and audio content, the core compression engine has the
possibility to find the optimal values for its parameters, at the cost of slightly
increased compression time only. The default recommended value is fast. do not use normal
(or even high or best) for this parameter unless encoding time does not matter and you
want to obtain the smallest possible file for a given compression mode. The difference
between the optimize levels fast and best (which is up to three times slower than fast) is
very small, generally under 0.05%, but may be also larger in some rare cases. Note that
the none optimize level is forced by the encoder to fast optimize level for the extra,
best, highnew, extranew, and bestnew modes.

available options are:

none
fast (default)
normal
high
best

--bratio num

set bonk down sampling ratio. default 2

--bquanl num

set bonk quantanization level. default 1.0

--bpsize num

set bonk predictor size. default 128
