Asunder : a simple and efficient encoder

FIXME : french shots to replace

Converting its audio CDs in multiple formats (Ogg, Mp3, Wav, Flac, WavePack, MusePack, Monkey's Audio or AAC) is possible with Asunder, the HandyLinux' encoder to ease your work.


To launch Asunder go through HandyMenu, Raiders tab, Debian Software and select Asunder in Multimedia Category. Main window appears : Starting Asunder There are 3 buttons :

  • CDDB Search which allows you to retrieve CD information,
  • Preferences which guide you to the Setting window (general, filenames, encode and advanced),
  • About which gives you information and site link Asunder.


Let's see what's in Asunder' settings.

General tab

General tab proposes :

  • choice of conversion destination (default in Home).
  • to create a “playlist M3U” file, which allows you to start playing an album with a single click (this file reflects the storage location defined at the outset. if you move the files, it is possible that this file does not work. Your audio files are still there but they are not related to M3U ​​file.
  • the location of your CD-ROM drive,
  • Audio CD ejection (or not) command at the end of encoding.

Onglet Général

Files name tab

This is where you define the name of encoded files. With the help you can name your files as you see fit. Onglet Fichiers

Encoder tab

Define here the conversion format of your audio CDs. You can select as many formats as presented. If you select more than one conversion format, your conversion folder contain several times the same tracks with different formats.

  • Most known format is MP3. is an encoding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players,
  • Ogg Vorbis is a free, open container format maintained by the Xiph.Org Foundation. The creators of the Ogg format state that it is unrestricted by software patents[2] and is designed to provide for efficient streaming and manipulation of high quality digital multimedia.

Other formats for various uses :

  • Wav is a Microsoft and IBM audio file format standard for storing an audio bitstream on PCs,
  • FLAC is a codec for lossless compression of digital audio. Digital audio compressed by FLAC's algorithm can typically be reduced to 50–60% of its original size and decompressed to an identical copy of the original audio data. FLAC is an open format with royalty-free licensing,
  • WavPack can compress (and restore) 8-, 16-, 24-, and 32-bit fixed-point, and 32-bit floating point audio files in the .WAV file format. It also supports surround sound streams and high frequency sampling rates. Like other lossless compression schemes, the data reduction rate varies with the source, but it is generally between 30% and 70% for typical popular music and somewhat better than that for classical music and other sources with greater dynamic range,
  • MusePack is an open source lossy audio codec, specifically optimized for transparent compression of stereo audio at bitrates of 160–180 (manual set allows bitrates up to 320) kbit/s. It was formerly known as MPEGplus, MPEG+ or MP+,
  • Monkey's Audio is an algorithm and file format for lossless audio data compression. Monkey's Audio does not discard data during the process of encoding, unlike lossy compression methods such as AAC, MP3, Vorbis and Musepack,
  • AAC is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC is the default or standard audio format for YouTube, iPhone, iPod, iPad, Nintendo DSi, Nintendo 3DS, iTunes, DivX Plus Web Player and PlayStation 3

Onglet Encodeur

Advanced tab

This tab allows you to set the method of retrieving information from audio CD and use a proxy or not. the default setting for CDDB is correct. If you use a proxy, remember to put the information to allow access to the CDDB. Onglet Avancé


Insert an audio CD and Asunder auto-opens. Here I will encode Courtney Barnett: The Double EP A Sea of ​​Split Peas. The CD is loaded, and if known from the CDDB database, the information is automatically inserted. At this point you can just click the button Extract and encoding begins with the settings set in preferences tabs. In this case, the CD will extract :

  • in my Home directory (dyp) with an M3U playlist file and the CD will be ejected at the end (General tab),
  • the files will be extracted to a directory on my personal folder with artist name and album title (%A - %L) and the files will be named Artist - Album - Track Num - Title (%A - %L - %N - %T) (Filenames tab ),
  • in MP3 format 320Kbps only (Encode tab).
