oggit
Version 1.5.0 (13 March 2011), copyright ©2005-2011 Brett Scaife
Introduction
oggit is a Perl script for encoding files in various audio formats to either FLAC or Ogg Vorbis format, with comments based on a template file and on any tags in the input file.
"Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. This places Vorbis in the same competitive class as audio representations such as MPEG-4 (AAC), and similar to, but higher performance than MPEG-1/2 audio layer 3, MPEG-4 audio (TwinVQ), WMA and PAC."
In other words Ogg Vorbis is a much better way to keep your music collection on your computer than MP3 - it's better quality and it's Free Software. Oggit provides an easy way to encode a WAV or MP3 file to Ogg Vorbis. It's designed to be used for fairly small numbers of files - it is not designed for batch processing of your collection of thousands!
FLAC stands for Free Lossless Audio Codec, a compressed audio format that is lossless, meaning that audio is compressed in FLAC without any loss in quality. "FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations."

Requirements
oggit requires:
- Perl
- Term::ReadLine::GNU
- MP3::Tag
- AudioFile::Info::MP4::Info
- oggenc
- ogginfo
- mplayer
- mpg321
- normalize.
- FLAC
- file, which should be part of most GNU/Linux distributions
Installation
You could simply unpack the archive and copy the files you want to the locations you want them but I've written a shell script that will install the files for you. Once you've downloaded the archive, unpack it:
tar xjf oggit-1.5.0.tar.bz2
Change to the oggit-1.5.0 directory and type:
./install.sh
Detailed instructions are given in the INSTALL file
distributed with the script.
Usage
oggit [template] filename
What it does
Once oggit has been invoked you have the following options:
- Change a comment's value
- Encode the file and save the present values to the template
- Encode the file and keep the old template values
- Turn normalising on/off
- Alter the encoding quality/compression level
- Change the encoding format
- Quit without encoding
Check the README file distributed with the script for
more details on how to use it.

14 January 2007
- Uses ogginfo to run a crude validity check on encoded file
1.2.3
