I have purchased some high-resolution music tracks from HDTracks. They are a mix of 96/24 and 88.1/24 encoded in flac format. I want to burn these to DVD-Audio disks so I can play them on the big speakers.
The only tool I have found for Linux is dvd-author. It works well on the 96/24 tracks, but fails on most of the 88.1/24 tracks. Does anyone have any ideas how to go about making DVD-Audio disks out of high-res flac files?
Here is the process I use:
1) Download the tracks from HDTracks.
2) Decompress to WAV using this command:
for i in *.flac; do flac -d "$i"; done
This produces a series of WAV files. No errors are produced at this step.
3) Generate the raw files image for the DVD-Audio disk. The command is:
dvda-author -o DVD -g *.wav
When this step runs, it generates a message for about 2/3 of the tracks "Padding track with 6 bytes".
4) Create a sort.txt file.
5) Create ISO image with this command:
mkisofs -o image.iso -sort sort.txt -udf DVD
6) Burn to a DVD-RW with k3b.
The problem is in step 3. Any track which was tagged with the "padding track ..." message will not play back. The sound is a hash of white noise. On some tracks you can hear the music way in the background, probably 30db below the noise.
96/24 tracks never produce the "padding with ..." message and always work.
If I take the same flac files and run them through the Windows program called "DVDA Solo", it produces an ISO file which plays correctly after burning to disk.
Amarok, Kaffeine etc. play the flac files correctly, though the computer is hardly a high-fidelity sound system.
The flac files play correctly on my Sansa Clip+ after I turn them into a downsampled Vorbis.
dvda-author is version 10.06-400 installed from the rpm. Linux is Fedora 14.
