A screenshot of Jack working (with comments)

Note that the xterm is automatically resized to fit all the tracks of the CD if you have xtermset installed (and enabled).

Jack is a console tool, somewhat in the great tradition of command-line oriented software. When using XTerm and xtermset the xterm's size is automagically changed to match the number of tracks. This is the meaning of the marked elements:

• 1: the options line: list general options like MP3 bitrate, the WAV read-ahead,...
• 2: the DAE speed: how much faster than real-time the audio data has been extracted
• 3: the DAE status: actually, this is the output of cdparanoia, check cdparanoia -h for details on the used characters, e.g. a "+" means "Unreported loss of streaming/other error in read".
• 4: the encoder status: while encoding, the percentage along with the ETA is displayed, afterwards the speed-factor is given, how much faster (or, like in the exaple, slower) than real-time the encoding was
• 5: DAE in progress: the greater-sign indicates how far the extraction of this track has come, again, this is cdparanoia output.
• 6: the status line: how much disc-space is left, how many WAVs are waiting to be encoded, how many subprocesses are idle, and, finally, the error status.
