Distortion in Windows Media Player

Have you ever listened to songs in Windows Media Player and found them to be distorted in places, so the sound quality is terrible? The same files may play perfectly in all other programs - I've had files that worked in WinAmp, RealPlayer, Quicktime, Nero, and a host of other programs with no problems, yet Windows Media Player would not handle them properly.

As it turns out, MicroSoft has a Creative PlayCenter MP3 decoder resident in the operating system which is what causes the problem. Certain versions of Windows Media Player use this decoder, but there are compatibility problems. If you're not using that decoder file for whatever reason, you probably won't run into the distortion problems.

The simplest way to fix the problem, assuming that you're running on a Windows operating system, is to go down to your start menu on the bottom left side of the screen, click on it, then go into "search." You need to search your C: drive (or whatever drive your O/S resides on) and look for a file called "Ctmp3.acm" - if you can find that file, don't delete it, just rename it to "Ctmp3.bak" instead.

If you can't see the file extensions when you're doing searches (the default option on Windows, but one which I detest and disable immediately whenever I set up a new computer), I'll show you how to make your file extensions visible. Go to Windows Explorer, either through your Start menu or by holding down the "flying window" key (left of your left side alt key) and then pressing the letter "E" at the same time. Next, go into the Tools menu, and chose Folder Options in the drop-down Tools menu. In Folder options, click on the "View" tab. The seventh or eight option in that list usually says "hide extensions for known file types" and has a check beside it. Uncheck this, then click OK. Now you'll always be able to see file extensions in Windows Explorer and associated panels. If you're quite computer savvy, you might also want to set the other three options above and below that let you show hidden files, show O/S files, and display the full path name in the Title Bar (although this is only applicable if you're trying to conserve system resources by switching to Classic View, such as for intensive audio or video processing).

Anyway, now you know how to show file extensions, and how to fix the distortion problem on Windows Media Player. This may not be a problem on newer versions of Vista, but it certainly was on certain versions of WMP running on XP.


If you want a different approach to disabling the problem codec, here's another set of instructions:

The Creative Playcenter software rudely blocks the Windows MP3 codec. The following instructions show how to unblock it on Windows XP system. The instructions for other Windows versions are the same except the steps to get to the audio codec area from the control panel varies. Note that this will disable the MP3 capability of the Playcenter software. You can re-enable using the same steps or replace the Playcenter software.

1. Go to the Control Panel
2. Double click on "Sounds & Audio Devices"
3. Select the "Hardware" tab
4. Double-click on "Audio Codecs"
5. Select the "Properties" tab
6. Double-click on ctmp3.acm
7. Select "Do Not Use this Audio Codec"
8. Then click on the "Apply" button
