The audio files of Star Wars: Knights of the Old Republic and Star Wars: Knights of the Old Republic II – The Sith Lords (KOTOR) contain extra headers of what seem to be superfluous data that obfuscate access to the original audio outside of the video games. Most audio software will refuse to open the files, or interpret the extra bytes as audio data, leading to glitches. It has also been observed anecdotally that files lacking an appropriate header may fail to playback in certain releases of the games.
SithCodec is an application that can automatically detect and remove an extraneous header from a KOTOR audio file, or alternatively prepend a KOTOR header to a standard audio file and allow for the introduction of new audio content to these games.
SithCodec requires Windows (32-bit or 64-bit).
Make sure to extract SithCodec to a folder where you have read & write permission.
The code is not signed (because code signing costs an extortionate amount of money) so your firewall may warn you about running an unrecognized application.
Commands in SithCodec are executed by combining keywords into certain command sequences that the application recognizes. Input may be passed as command-line arguments when SithCodec is launched, or entered manually through a command- line interface if the application is launched without any command-line arguments.
Keywords may be entered in short form (dash followed by a single letter) or long form (double dash followed by a full word).
SithCodec keywords are not case sensitive, but—depending on your operating system—other data that you input may be, such as the names of files.
Entering -h or --help will display the help screen, showing a list of all keywords and their function.
