Convert HEX files to WAV using Conv2Wav

It has been suggested to use Conv2Wav to convert hex files to wav. HEX? Where does one get a hex file from an mp3? It was suggested to use either L3Dec or Mad and I don't see where or how you can get a hex file. Thanks

If you have the Fraunhofer decoder l3dec.exe, you would call it as follows:

l3dec -h24 file.mp3 file.txt

It's commercial and not being sold anymore.

You will only find it in Warez sites.

I'm not entirely sure why anyone would want a 24-bit wave file from a decoded MP3 (which was 99.9% likely from 16-bit original source anyway).  Can someone enlighten me on this?

A CD could have used dithering, and thereby captured some information below the 16-bit noise floor.  Encoding to mp3 does not have to destroy this information (encoders use floating point values).  Thus, playing back at 24 bits could retain this information.  Some people can tell the difference between 24-bit playback and 16-bit playback.  See, for example, Nawhead's test of the MAD decoder at 24 bits:

Apparently, though, MAD's 24-bit routine is a little bit off (must be less than the left buttock of a gnat's ass), whereas l3dec is perfect.  So if you're a real anal type, you might prefer using l3dec's 24-bit output over MAD's.  Assuming you can tell the difference between 24 bits and 16 bits (I can't).

I'm being advised to use L3Dec to decode an mp3 to hex. Would you please tell me what advantage if any can be gained by doing this.

Then, to use conv2wav to convert hex into wav.
Then to use Cool Edit Pro to downsample to 16 bits. Why downsample to 16 bits? Wouldn't sound quality be lost by doing this? Thanks Jeff

If you have amazingly good ears, a perfect MP3, a killer sound system, and a quiet environment where you can listen to your music with anal-retentive dedication, then you might gain some tiny advantage.

In other words, don't worry about it. If you want to put MP3's on a CD, it's probably because you downloaded them and you don't have the original CD. In this case, the MP3's aren't going to be perfect anyway, so there's no real reason to stress about retaining the dithered bits since the artifacts are going to be much more apparent.

Just load the MP3's into Nero or Easy CD Creator and burn. The time and effort savings is worth much more than the slight (read: imperceptible for me) degradation in quality.

If you won't be able to enjoy your MP3's unless you feel you spent too much time preparing them, then use Winamp with the MAD input and Diskwriter output, TURN OFF YOUR EQUALIZER, and burn the MAD audio files. Or you could use the MAD frontend that rjamorim mentioned.

Spend less time stressing, spend more time listening!
