Well, I guess this is a software issue since I have performed tests to rule out everything else. My Pioneer car cd player (DEH-P860mp) produces a popping/cracking noise when playing some (not all) WMA files burned to CD's. The noises occur at the same position within the track every time the affected files are played; however, these noises are not reproduced when playing the same disk on any other device (e.g. computer, home stereo, etc). If the same song is encoded as an MP3 file, the noise does not occur. I have tried different disks types and brands and even switched CD burners, and the results are always the same with this unit. I have also tried creating CBR and VBR WMA's of the affected files at different qualities with no success. I have narrowed everything down to assume that my encoding is the problem, because these noises still occur on other Pioneer decks. Since these noises are very loud and disruptive, I am inquiring if there might be any solutions for this problem?
Here is the quick run down for you...
- Windows XP Professional SP2
- Toshiba DVD-ROM drive (SD-M1712)
- LG Multi-funtion DVD writer (GSA-H55L)
- Windows Media Player 11 (for encoding CDA to WMA)
- Nero 6 for everything related to disk writing
Situations that result in "pops" during playback:
Playing store bought CD on Pioneer - no
Playing WMA version of that CD - yes
Playing MP3 version of that CD - no
Playing WMA version with VBR - yes
Playing WMA version on CD-RW disks - yes
Playing WMA version on nearly every brand I could find - yes to all
Burning WMA version at slower speeds - yes
Playing WMA version on DVD-ROM, DVD Player, Home Stereo, etc - no
Using Nero to encode CDA to WMA - yes
Using Windows default disk writing program - yes
WMA playback from the hard drive - no
Using Nero's Wave Editor software, I was able to view the burned WMA's wave patterns and saw no strange spikes or distortions in the signal. I have spent days testing and searching this forum to find solutions to this issue. What is going on?
