I was wondering if I could get some input with burning audio CD's of out of 24/96 flac files. I've burned a number of files lately using dvd audiofile with mostly good results. Some of the files it won't make an image out of and I suspect this may be due to some files being in the newest flac codecs. I even tried to download a program to decode the new flacs (on a mac) and than re-encode them in an earlier version of flac, but have not had any success. Any thoughts on how to do this?
Thanks in advance!
Full Version: help with burning 24/96 files
You do know that any and every audio CD must be 16/44.1kHz? You must either convert to 16 bit and resample first or find some CD-R writing application that will do it in real time as the disk is being written.
I can’t say if there is or isn’t such a program because I would never take that second approach. The majority of resampling programs are less than optimum quality. I would always create 16/44.1 files before starting the write to CD-R process to assure I have the best quality resampling and that nothing goes wrong while writing the CD-R.
If starting with FLAC, that means I would from decode to wav, resample to 16/44.1, write to CD-R, then delete the wav files if I had no other use for them.

Aren't audio CDs obsolete by now? Consider burning to "Audio DVD" instead. This format should be compatible with all DVD video players. "Audio DVD Creator", "Apollo Audio DVD Creator", "Audio DVD Maker" can be used to create them, but only under Windoze. (don't know if Corel Burn.Now is available for Mac) You may be able to do the same thing by using a DVD video authoring tool to make a "slideshow", and use the high quality audio file to accompany a single slide, like the album artwork.

I thought that the only uncompressed audio format for video DVDs was 16 bit 48 kHz? This is virtually identical to CD audio quality, just higher capacity.

Many of those tools (Audio DVD maker, Audio DVD Creator) re-samples everything to 48 kHz. If you are aiming for maximum sound quality, you do not want to do that, unless you are sure that they are using a high-quality re-sampler. Even going up in the sampling rate suppose recalculating and recreating each point of the waves when one figure number is not a multiple of the other.
(Of course, if your hi-res files are 48 kHz, no problem).
DVD-Audio allows for many sampling rates and many bitrates. Including redbook's 16/44.1. The only tool I came across, so far, that allows you to stay 16/44.1 is WaveLab.

No...http://en.wikipedia.org/wiki/DVD-Video#Audio_data
Not that wikipedia is definitive, but in this case it's correct - though it doesn't explicitly state that 6-channel 24-bit 96kHz audio is too high a raw datarate for DVD video, hence MLP on DVD Audio.
Cheers,
David.

I actually meant audio DVD's. Dvd audiofile is very good in general but is finicky with some of the new flac encoding. Toast works also but tends to skip around in between tracks which is very annoying.
Oh, and just to clarify, I want to keep the sample rate at 24/96 and not downsample to 16 bit.

I see. How about decompressing the flac to wav first?
And for what it's worth, searching for "DVD Audiofile" led me to this FAQ which lists some more authoring tools: Basic 24 Bit FAQ

Actually Dvd-audiofile has problems with wav files unfortunately. I need to look at these other programs. I wonder if they work for macs?

That's just plain weird. I wonder if they're in the wrong wav format? When I recorded at 24/48 with Audacity, it defaulted to "Microsoft 32 bit float" for exporting as a wav. This was incompatible with a lot of applications (AudioDVD Creator, WinLAME, WaveStudio), although a couple of players were OK with it. "Microsoft signed 24 bit PCM" turned out to be the proper choice.
