Ubuntu - CD - Write audio CD
Using cdrdao (DAO)
The “Disc at once” (DAO) feature allows one to burn an audio CD without the two second gap between tracks. This is most useful when copying CDs as it allows one to burn the CD to be just like the original. The cdrdao command uses a “table of contents” (TOC) file as shown below.
Usage:
cdrdao command [options] toc-file
Example:
cdrdao write toc-file.toc
| Command | Description |
|---|---|
| show-toc | Prints out table of contents (toc) then exits. |
| toc-info | Prints out short toc-file summary. |
| toc-size | Prints total number of blocks for toc. |
| read-toc | Create toc file from audio CD. |
| read-cd | Create toc and rip audio data from CD. |
| show-data | Prints out audio data and exits. |
| read-test | Reads all audio files and exits. |
| disk-info | Shows information about inserted medium. |
| unlock | Unlock drive after failed writing. |
| simulate | Shortcut for 'write –simulate'. |
| write | Writes CD. |
| copy | Copies CD. |

| –driver driver-id | Force usage of specified driver. |
| –source-driver driver-id | Force usage of specified driver for source device. Used by 'copy'. |

See cdrdao examples and how to generate a toc file to control gaps (or lack thereof) during CD burn.
Create toc (table of contents file) which shows(read)/determines(write) the gaps in tracks.
cdrdao read-toc --driver generic-mmc-raw --read-raw --device 0,4,0 toc-file.toc
Sample TOC (Table Of Contents) file:
CD_DA CATALOG "0075590506829" // Track 1 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO SILENCE 00:01:00 FILE "data.wav" 0 03:28:70 START 00:01:00 // Track 2 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "data.wav" 03:28:70 02:14:45 START 00:04:52 ... .. // Track 10 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "data.wav" 26:05:40 05:03:37 // Track 11 TRACK AUDIO NO COPY NO PRE_EMPHASIS TWO_CHANNEL_AUDIO FILE "data.wav" 31:09:02 04:50:50
Minimal example:
CD_DA TRACK AUDIO AUDIOFILE "song1.wav" 0 TRACK AUDIO AUDIOFILE "song2.wav" 0 TRACK AUDIO AUDIOFILE "song3.wav" 0 ... ..
Where the “0” refers to the beginning of the file.
