Thanks Karl and 'schunn' ([EMAIL PROTECTED]) for your replies.
I played the .wav files generated by cdda2wav and the noises are all there in
the .wav files. Thus, the burning was OK, the audio extraction from the CD was
the problem.
now that I think of it, I started using cdda2wav based on the responses given by
Jörg on a recent thread (how to merge two ripped CDs?). It was far easier to
have all .wav and .inf files wherever you want and then use cdrecord to burn (in
dao mode) whatever tracks you wanted to.
As Karl said, cdparanoia (which is what cdrdao uses to rip audio data to disc)
does correction and verification. Perhaps this is why I had never noticed a
similar problem before (or perhaps it was just luck).
Summarizing:
If you set cdrdao's paranoia mode to 0 (zero) then cdrdao will read audio like
cdda2wav does. The default however is the full paranoia mode.
>From the cdrdao man page:
--paranoia-mode mode
Sets the correction mode for digital audio extrac
tion. 0: No checking, data is copied directly from
the drive. 1: Perform overlapped reading to avoid
jitter. 2: Like 1 but with additional checks of the
read audio data. 3: Like 2 but with additional
scratch detection and repair.
The extraction speed reduces from 0 to 3.
Default is the full paranoia mode (3).
>From the cdparanoia man page:
In addition to simple reading, cdparanoia adds extra-
robust data verification, synchronization, error handling
and scratch reconstruction capability.
[snip]
-Z --disable-paranoia
Disable data verification and correction features.
When using -Z, cdparanoia reads data exactly as
would cdda2wav with an overlap setting of zero.
