The Digital Audio EXtractor, or DAEX, extracts digital audio from an IDE (ATAPI) CD-ROM. As long as your drive supports CDDA (CD Digital Audio), you should have no problems getting DAEX to run.

DAEX is freeware.

  FreeBSD 2.2.6 -> 3.0

Patches (see Patch Downloads) are available for the following platforms:

 FreeBSD 2.2.6-RELEASE and 2.2.7-RELEASE
 FreeBSD 3.0-CURRENT (as of 3.0-19980804-SNAP -- also works under FreeBSD 3.0-RELEASE)

Click the appropriate link below for the latest DAEX kernel patch:

FreeBSD 2.2.6-RELEASE and 2.2.7-RELEASE
FreeBSD 3.0-CURRENT (as of 3.0-19980804-SNAP -- also works under FreeBSD 3.0-RELEASE)

Patch installation

To install the ATAPI modifications to your FreeBSD kernel, follow below.

The example uses a FreeBSD 2.2.6 system. The commands in bold face were entered as root:

   earthtone:~# whoami
   root
   earthtone:~# patch -p < atapimods_1.0_freebsd2.2.6-release.patch

At this point, the following files are modified:

   /usr/src/sys/i386/isa/atapi.h
   /usr/src/sys/sys/cdio.h
   /usr/include/sys/cdio.h
   /usr/src/sys/i386/isa/wcd.c

Once you have installed the above patch file, you will need to recompile the kernel. It is _strongly_ recommended you back-up your current running version of the kernel. An example follows.

First, back-up your current version of the kernel:

   earthtone:~# cd /
   earthtone:/# cp kernel kernel.nodaex

Next, recompile, and install the resulting kernel:

   earthtone:/# cd /usr/src/sys/i386/conf
   earthtone:/usr/src/sys/i386/conf# config GENERIC
   Kernel build directory is ../../compile/GENERIC
   earthtone:/usr/src/sys/i386/conf# cd ../../compile/GENERIC
   earthtone:/usr/src/sys/compile/GENERIC# make depend
   earthtone:/usr/src/sys/compile/GENERIC# make
   earthtone:/usr/src/sys/compile/GENERIC# make install

Finally, reboot the system:

   earthtone:/usr/src/sys/compile/GENERIC# reboot

If you encounter any errors, please feel free to drop me a note. Please include any relevant information that will help me debug the problem.

DAEX Download

Click the appropriate link below for the latest version of DAEX:

DAEX v0.40a
DAEX v0.90a

You should be able to compile the source immediately after you've uncompressed the archive. However, it is possible that the Makefile included in the distribution will require minor modifications.

To extract, and compile DAEX, enter the following (the bold face indicates what you should enter):

  earthtone:~$ tar xfz daex.tgz
  earthtone:~$ cd daex
  earthtone:~/daex$ make

To install DAEX, enter the following as root:

  earthtone:~/daex# make install

DAEX is installed set-UID root, so that it may access your CD-ROM device. If this isn't acceptable, you may remove the SUID bit, or change the owner/group permissions to fit your requirements. DAEX (obviously) must still be able to access the CD-ROM.

You should now be able to begin extraction.

DAEX Caveats

DAEX does not currently support jitter correction (though, it should by the first major release).

This alpha version does not support multiple matches from the CDDB server. I hope to have this feature in before beta. Silly, but I haven't had a whole lot of time to spend on it. :(
