cd2flac

Description

The cd2flac script performs secure extraction of audio tracks from a compact disc, and encodes them in FLAC format. This script sports the following notable features:

  • multiple passes, MD5 hashing and matching to ensure accurate extraction
  • track 1 pregap "hidden" track detection and extraction
  • metadata editing, populated from MusicBrainz, based on calculated disc ID
  • track number offsetting to allow multi-disc releases to be compiled into a single album
  • sector offset correction

Dependencies

Notes

  • This script is tested on Ubuntu 8.10; mileage may vary on other platforms.

Tracks

This script supports a flexible way of expressing the track numbers to extract. Ranges and commas supported. Example: 1-2,4,6-8,11-. If no tracks are specified, all are extracted.

Track offset

The --trackadd option allows multiple discs to be easily compiled into a single album. Set the value to what should be added to the track number of tracks on the disc. Negative values are also permitted.

Templates

An album template allows a template of metadata to be established so that the appropriate tags are displayed in the context. For more information, see the metaedit command help.

Configuration file

You can store persistent command-line options in a file called .cd2flac in your home directory. They will be read as defaults prior to processing any passed command-line options.
