Audio

---

The external tool used by Xena to convert audio files is FLAC (Free Lossless Audio Codec).

During compression, FLAC does not lose quality from the audio stream, unlike lossy compression formats such as MP3 and AAC.

• FLAC (http://flac.sourceforge.net) is a free and open source software tool and file format for lossless audio data compression.

Location of external program

Depending on your operating system, the FLAC executable may be included with the Xena package. If so, the executable will be located within a sub-directory of the directory containing the Xena program (xena.jar). Otherwise, the executable must be installed separately.

• Linux - install flac via your distribution's package manager. After installation, the flac executable is most likely located under /usr/bin/.
• OS X - the file is called flac and is located in the macx86 sub-directory.
• Windows - the file is called flac.exe and is located in the winx86 sub-directory.
