Authoring 24-bit audio CDs.
Kernel, GNU (slackware 12.0).
KDE 3.5.7
K3b 1.0.2

I have a FLAC file with 24-bit samples instead of 16 bits. I could use the flac linux command to obtain a WAVE file and then cdrecord to burn the audio CD. Unfortunately, cdrecord requires 16-bit digital audio as input. Is there a program able to author 24-bit audio CDs either from a FLAC file or from a WAVE file? Thanks in advance.

Nope, I'm afraid not. Audio CDs are always 16 bit.

Yes, dvda-author can do that.
24 bits will anyway use some more space : Then DVD instead of cd.
And DVD-audio provides excellent sound.
Most modern quality DVD players can probably do DVD-audio ?

dvda-author -o DVD -g *.wav -X 'working directory'
etc. etc.

When I made a test DVD-audio three years ago :
It wasn't very difficult : A couple of edits in the text file
for : mkisofs -o image.iso -sort sort.txt -udf DVD

Good luck !

P.S.: More info :

Very kind of you to have answered my post, knudfl. There is a lot of info in your post. I have to study it carefully. As a first step, I must study the flac command man page, as I must get a WAVE file out of the FLAC file, keeping all the metadata if possible.

This flac file I have, was uploaded by a guy who claims to have used high-end analog equipment to make the transcription from an LP record. "The LP transcribed for this torrent is in exemplary condition throughout", he adds. And he lists the audio components used in the transcription all the way from the phono cartridge up to the A/D converter.

However, I don't see the point in making 24-bit digital audio out of a vinyl disc. Add to this my stand-alone player is not able to reproduce DVD-audio (although I could have such a one in a near future, one never knows). So, I think I will trim it to 16 bits and make an audio CD out of this file.

To honest, I am doubtful. All this started when I put an LP recording of Mozart's symphony no. 41 in my turntable and found the last movement was badly scratched. Although I knew I would never recover the treasure I had lost (it was a recording by Bruno Walter), I immediately set to find a new recording of comparable merit. And the result was this. Well, enough of this stuff and, again, thanks.

Well, the original recording will always have the best sound
from a high quality record player, by my opinion.

I use the 'Denon DL-103 R' Cartridge, which is also one of the
best not to pick up noise, when the recording has been worn by
an elliptical cartridge. (DL-103 : all versions are spherical).
For best noise suppression also : A high bandwidth preamp is
But if you have cross scratches : Not much to do.

Classical recordings come in abundance here in Europe.
People used to give them away. No or little commercial
value. Should be possible to find a replacement on the
internet. Which recording id number is it ? Old 78rpms ?

There also used to be a Sony CD ( reprocessed ? ) :

Burning 24bit FLAC to DVD : Commercial software ?

The link you gave me (Sony) is exactly the LP recording I have. It has the same cover. The record is a CBS Masterworks, Estero, ID= 5046. The CD is obviously reprocessed (obvious for me) because I bought it in 1968, long before the compact discs appeared in the market. Besides, Bruno Walter died in 1962 (they made excellent recordings long before that). But the page where your link directs says Availability: Out of print.

You say you own a Denon DL-103 cartridge. Are hi-fi cartridges easy to obtain these days? If you see the Shure catalog, you'll find almost all models are for disc-jokeys.
I suppose the eliptical stylus is the right choice when the record is new. I have an old Shure V15 type II Improved, but the stylus is almost new, and a Yamaha C-2 preamp. But I'm not sure about the quality of my sound card.

Why do you ask about the 78rpms? Well, thanks infinite.

EDIT: I've been reading your links, specially 24bit.turtleside, which is enlightening and seems written by a person who knows. Thanks a lot.

Eliptical : One story tells, they were originally made to
get reasonable sound from mid class record players with
non perfect tonearms. Runs in the bottom of the track.

The original spherical DL-103 was developed for the 'Japanese
Broadcast' about 30 years ago. Tracks the music where it is
meant to run. I use it with an Origin Live 300 tonearm.
The deck is an old Thorens TD 166 MK II : Perfect sound.
And can play records impossible to listen to with an elliptical
cartridge. Result : No noise, no scratch.

Buy any hi-fi magazine : Some have a list with all cartridges,
etc. in each issue.

The good offers can be found on Ebay ( UK )
