Greetings,
I'm curious what the best method for creating an Audio CD is. I have a bunch of music (MP3) from various games that I wanted to burn to CD for listening to in the car. Unfortunately the two methods I tried failed miserably:
1. Drag the MP3s into Nero 7 and burn a new "Audio-CD"
The end result was very low quality. The source MP3s were 2ch 48khz 224kbps but the resulting CD sounded more like 22khz "radio quality" WAV files
2. Drag the MP3s into Nero 7 and burn a new "CD-ROM (ISO)"
The end result was the disc doesn't play in a standalone player. I can access the files via Windows Explorer and play them though.
Thanks |

Maybe the CD-player in your car is not able to recognize data-CD's and neither to play MP3 ?
Maybe it has also difficulties to read CD-R / CD-RW media ?
For as far as I know standard Audio-CD's have uncompressed WAV-files on it, sampled at 44.100Hz.
JUST TO TRY:
You could do a test by downloading and installing Audacity:
http://audacity.sourceforge.net/
This software should be able to open your MP3 files and to modify the sampling rate (via the button in the lower left corner).
You can make the WAV-file of it via File > Export as WAV...
Now via Windows Media Player and its 'Burn'-function, you can drag and drop the WAV-files to it, and finally burn the Audio-CD (via the "Start Burn" icon). |

Audio CDs are 44KHz, 16-bit stereo. An MP3 has to be decompressed to be burnt onto an audio CD, but that's perceptually lossless. 48KHz audio also has to be resampled to 44KHz too, but you shouldn't notice that unless the tool that did the conversion is lousy at it (which, unfortunately, can't be ruled out).
The first thing I would do is check the audio CD in your computer to see if it plays poorly there. If it's OK, then you might try burning the audio CD at a slower rate. Audio CD players aren't always as good at reading CDs as a computer or DVD player drive, and burning at a slower speed (8x or slower) can give a better result. Audio CDs are encoded with less error correction than data CDs and as the drive has more trouble reading the CD the audio quality will degrade. Still, the result you're hearing sounds like more that could be explained by read errors. If the audio CD is also poor when played on your computer then you should try what Abrazo said and use Audacity to pre-convert the audio tracks first.

Thanks everyone. I found the best option was to convert them myself before burning. |
