[Cdrdao-devel] read-toc: Track 1 pre-gap

[Svend S. <sso...@gm...>]

I have noticed that if the first track has a pregap, it is added to
the TOC file as SILENCE.  As an example:

// Track 1
// pregap as SILENCE
TRACK AUDIO
TWO_CHANNEL_AUDIO
SILENCE 00:00:32
FILE "data.wav" 0 01:31:08
START 00:00:32

<snip>

// Track 8
// pregap as FILE index
TRACK AUDIO
TWO_CHANNEL_AUDIO
FILE "data.wav" 24:22:45 05:08:28
START 00:00:10

Is this due to a restrition on the CD format (where the first track's
pregap must be silence).  Is the audio data that is in this pregap
generated on the fly as zeros when reading (so it does not take up
space)?  I am curious, because when EAC generates a CUE file for this
same disc, it does not use the equivalent PREGAP (generate silent
pregap) keyword.  The 32 frame pregap is read as index 0 and 1 in the
file:

FILE "data.wav" WAVE
  TRACK 01 AUDIO
    INDEX 00 00:00:00
    INDEX 01 00:00:32
