What would be a good way to burn high res audio to normal CD-Rs?

I'd like to burn a CD from some FLAC files that are 24bit 96000Hz. Is there a tool that can do this all in one step?

Cheers :)

If you're trying to create an audio CD you'll have to resample to 44,100 Hz, 16-bit, stereo.  It's better to handle this kind of thing in separate steps.  I'm not aware of any specific tools that allow this all in one step.

Dang. Guess I'll have to re-learn how to use sox again, heh

Code: [Select]
sox input.flac -G -b 16 output.flac rate -v -L 44100 dither

And I recommend CDRTFE as a burner.

Last I used it, CDBurnerXP was able to do this in one step.

foobar2000 can also do it with the "SoX Resampler" and "Smart Dither" components in the DSP chain.

Actually, even built-in resamplers and built-in "Dither" feature are enough for high quality conversion on-the-fly.

Like pretty much mentioned above I would run any high-res files (basically anything above 44.1Hz) through Foobar2000 with the 'SoX' plugin to convert back to standard 16/44.1 and then you should be able to burn a standard audio CD with your favorite burning software.

p.s. I use ImgBurn (which is pretty much the best all-around burning software in my opinion) to burn standard audio CD's (and general data CD/DVD). it's interface is not as straight forward for burning standard audio CD's though, but is still easy enough once you know what to do (i.e. 'Tools > Create CUE File...' then add in your WAV files, save the cue file, then 'Mode > Write' and drag-and-drop the CUE file in here, select your burn speed (I suggest 16x for audio CD's) and then burn). but since I am using ImgBurn on Linux I temporarily convert FLAC back to WAV with Foobar2000 as ImgBurn can directly use WAV files without issue on Linux but will likely have issues on any other format besides standard WAV files.
For music I suggest (using Foobar2000)... MP3 (LAME) @ V5 (130kbps). NOTE: using on AGPTEK-U3 as of Mar 18th 2021. I use 'fatsort' (on Linux) so MP3's are listed in proper order on AGPTEK-U3.

I would simplify that to:
Code: [Select]
sox input.flac -G -b 16 output.flac rate 44100
  • -L is the default
  • -v seems pointless when the output is 16-bit
  • dither is applied by default when the output is 16-bit

Converting with resampling and -G by separate tracks can change original loudness difference between tracks in album if clipping will occur and -G will act.

Also, resampling by separate tracks can sometimes lead to audible clicks between tracks if original transition between tracks is not silent. When converting with foobar2000 this can be prevented by using option "Don't reset DSP between tracks". Although option is not available in foobar2000's CD burner settings. Can this be that in CD burner DSPs aren't reset by default? Also foo_dsp_resampler (SoX based) (https://hydrogenaud.io/index.php/topic,67376.0.html) and foo_dsp_src_resampler (https://www.foobar2000.org/components/view/foo_dsp_src_resampler) are preventing clicks between tracks even without "Don't reset DSP between tracks" because of extrapolation in the beginning and in the end of tracks.

Thanks for all the tips :)

If it is about storing your audio, just burn the FLACs straight to the CDr, DVDr, or BD-RE.

Its for audio CD. :)

Is there a way to change this bat file to output .wav?

Code: [Select]
D:
cd %~dp0
mkdir converted
FOR %%A IN (%*) DO sox %%A -G -b 16 "converted/%%~nxA" rate -v -L 44100 dither
pause

No edit..

I hope im doing this right.. ?  hehe

Code: [Select]
D:
cd %~dp0
mkdir converted
FOR %%A IN (%*) DO sox %%A -G -b 16 "converted/%%~nA".wav rate -v -L 44100 dither
pause

It should work? If not, put the .wav inside the quotation mark.
%%~nA.wav"

It works. I just want to make sure that is the proper way to get the proper files. Since I have no real idea what im doing, lol. :)

It creates .wav files that foobar says is PCM. So I guess its good? heh

Yes.  "Regular" WAV files are uncompressed PCM.   It's possible to have other formats in a WAV file but every WAV I've seen is PCM.

The sample data on the CD will be identical to the data in the WAV file but on the audio CD it won't be in a "WAV container".

On DVDs they call it LPCM (Linear PCM) but CDs are also linear.  


Back to your original question....   I think most burning applications will automatically convert to the audio CD standard as long as you configure it to make an "audio CD".   But I've never tried it .  I've always used stereo 16-/44.1.    And you might not get the "best" quality with the built-in re-sampling but I've never heard any difference no matter what I was using for resampling.
