Cdrdao ~ Disk-At-Once Recording

Posted by tom2tec on

Cdrdao records audio or data CD-Rs in disk-at-once (DAO) mode based on a textual description of the CD contents.

Advantages of Disk-At-Once (DAO) Recording:

Recording in disk-at-once mode writes the complete disc, i.e. lead-in, one or more tracks and lead-out, in a single step. The commonly used track-at-once (TAO) mode writes each track independently which requires link blocks between two tracks. Older CD-recorder models forced a two second pause (pre-gap) between two tracks whereas newer models allow adjusting of the pause length in TAO mode reducing the number of link blocks to a minimal amount. However, with TAO it is generally not possible to define the data that is written in pre-gaps. But exactly this feature makes audio CD recording interesting, e.g. by creating hidden bonus tracks or track intros in pre-gaps like it is common habit on commercial CDs. Finally, DAO recording is the only way to write data to the unused R-W sub-channels for e.g.  CD-G or CD-TEXT.

Features:

  • Full control over length and contents of pre-gaps (pause areas between tracks). Pre-gaps may be completely omitted, e.g. for dividing live recordings into tracks.
  • Control over sub-channel data like:
    • catalog number
    • copy, pre-emphasis, 2-/4-channel flags
    • ISRC code
    • index marks
  • Support for exact audio, data and mixed mode CD copying.
  • Support for R-W sub-channel writing.
  • Tracks may be composed of different audio files supporting non destructive cut.
  • Accepts WAVE and raw audio files.
  • CD-TEXT reading and writing with drives that support it.
  • CDDB access to automatically create CD-TEXT data.
  • Support for on-the-fly copying.

Streamripper ~ Record Shoutcast-compatible Streams

Posted by tom2tec on

Streamripper was started sometime back in early 2000. Streamripper started as a way to separate tracks via Shoutcast’s title-streaming feature. This has now been expanded into a much more generic feature, where part of the program only tries to “hint” at where one track starts and another ends, thus allowing a mp3 decoding engine to scan for a silent mark, which is used to find an exact track separation.

Streamripper is now part of the FreeBSD standard distribution, mentioned in the Linux MP3 HOWTO, known to compile on many platforms such as Linux, Windows, FreeBSD, BeOS, OS/2. This is not surprising as portability was a constant consideration during development.

With the emergence of file sharing protocols such as Napster, Gnutella, and now Mojonation and Freenet, the average Internet user can download nearly any mp3 he wants in a matter of no time, but many times people don’t know what they want. Streamripper allows you to download an entire station of music. Many of these mp3 radio stations only play certain genres, so you can now download an entire collection of goa/trance music, an entire collection of jazz, punk rock, whatever you want.
