Are you having problems with sound quality when you use our audio dictionary software? If so please read the advice that follows. MP3 Codecs and Filters With the default Windows setup, the Windows Media Player system component (msdxm.ocx) that plays the program's audio works well. However, with the great flexibility that Media Player provides, and the various third party multimedia devices that users install, sometimes things can get complicated. If you use our software and you hear crackly, broken or shortened audio clips, it is most likely to be due to an audio codec problem. Unfortunately (or fortunately for Windows Media Player users), this poor audio quality does not appear to occur when playing audio through the latest version of Windows Media Player. So how do we work round it? Look in the Windows Media Player folder (C:\Program Files\Windows Media Player) and find the file named mplayer2.exe. This is the earlier version of Media Player included by Microsoft for 'trouble shooting'. Open mplayer2.exe and then open an audio clip from the Learn Thai audio folder. If you cannot find mplayer2.exe, click here to download it.
Play any of the mp3 audio files, and then click the File menu > Properties > Advanced tab. You will see which audio codecs are in use.
With a problem free setup, the MPEG Layer-3 Decoder should be listed. A click on the properties button would show that this is the Fraunhofer IIS codec.
If you have a problem then it is most likely that the Fraunhofer Codec is not being used, and this can be caused by the presence other codecs. Sometimes removing all the codecs and allowing Media Player to automatically install the right ones will cure this. Here is a look at the Windows Control Panel screen that allows you to manage your audio codecs. NOTE: The codecs shown in the image represent an example and will differ between individual computers.
This screen is accessed by clicking Start > Settings > Control Panel > Sounds and Audio Devices > Hardware > Audio Codecs > Properties. Right click on a codec in the list to edit its priority, disable it or remove it. What if this does not work? It has been known that the presence of a codec that was not listed in the audio codecs device manager has caused problems. There are 2 known cases: Case 1: IVIAUDIO.AX Look for these files in the folder C:\WINDOWS\SYSTEM32\ or download our audio codec renaming tool. In each case renaming the codec file to IVIAUDIO.OLD or AC3AUDIO.OLD respectively, and restarting the computer, forced the system to use another codec, in these cases the MPEG Layer-3 codec. There is a Microsoft article that prescribes this solution for a completely different problem concerning their Combat Flight Simulator product.
