Hello everyone,

I've released ddptools 0.8.5a, a set of command line programs to
create, read and export audio from DDP images for CD audio. Due to
the license of the official DDP specification these tools are not
open source, but simple "freeware" at the moment, which I hope
people will not mind too much.

Details are found at http://ddp.andreasruge.de.

The two main programs are:


1) cue2ddp - Create CD audio DDP 2.0 images from cue/wav images

Features include:
* track start, pause and index markers
* ISRC, catalog number (UPC/EAN)
* all track flags (pre-emphasis, copy permission, SCMS, 4ch)
* all CD Text fields


2) ddpinfo - Display, check and export CD audio DDP images

Features include:
* display of all content from a DDP images (except the audio)
* full PQ listing, CD Text fields
* verification fo MD5 and CRC32 checksum files
* export of audio as (Broadcast) Wave files including time stamp
  and track start positions as cue points
* full DDP to cue/wav conversion, for burning or playing


I'd like to encourage everyone interested to test the programs as
hard as possible. I'm also planning on setting up a small test suite
with real world examples of cue sheets and DDP images. As you might
know cue/wave, cue/bin and DDP images come in many different
flavors, some of which are really difficult to foresee. So, if you
have software that generates either cue/wav or cue/bin images or DDP
file sets, I'd like to ask you to prepare and send me a simple
example image.

Here are the instructions:

* Any audio will do, but no more than 30  seconds please (~ 5 MB).
Set a few tracks and use all options available, like pause markers,
track indices, flags, ISRC, UPC, and especially CD Text. Fill all CD
text fields offered and make sure at least one field has a double
quote and a non-ASCII character inside.
* Let me know which software you used to create the image
* optionally: include a screen shot of the track/PQ/CD Text editor view
* send the image as compressed email attachment

Aside from that any feedback and ideas are welcome.

Best
Andreas
