do you remember which program does that?
to comment on quoted text by jkh -
This sounds like wrong statement. Granted, it takes a little
time to learn how to use cdrecord on Linux, but then I was able
to write multi-session (data and audio) CDs with tracks copied
by cdd on FreeBSD. On Linux, it was done under X with lightly
loaded system, separate SCSI buses for disk and recorder,
and 2-speed writer. Recently, a FreeBSD port of cdrecord was done.
A stripped-down system (no daemons running, no networking except
when downloading files to be written to CD) - just console -
should not get any competition as you describe it. You can
even run single-user.
Of course, if you don't know how to use FreeBSD or Linux for this
correctly, it is your right to use DOS from Micro$oft - after
all, they also made NT, which is better than Unix in networking . ;-)
As for short gaps, well, there is `disk at once' mode which allows
to write any data to CD. But then, let me quote README.audio from
cdrecord package by Joerg Schilling:
<<<<
Cdrecord crently only supports Track at once. This gives 2 seconds
pause between two audio tracks.
The 2 seconds pause between two audio tracks is the CD ***standard***
The standard says:
Each track starts with 2 seconds of silence
followed by at least 4 seconds of audio data.
For that reason the 2 second pause is generated by the CD-R drive in
Track at once (TAO) mode.
CD's that have no pause bewteen two tracks are illegal.
These illegal disks may be made with Disk At Once (DAO) only.
In DAO mode the writing software needs to send the 2 seconds pause as
binary zeroes and therefore is able to create illegal disks by
sending audio data instead.
