FAQ

• When I am trying to convert a wave file that I created with Sound Recorder, the produced amr file is only 18 seconds long. What can I do?
• Just reconvert the wave file to a 16bit 8hz frequency file (mono) with Total Recorder or Winamp.

• I am trying a WAVE to AMR conversion and I select input and output file (yes, 16 bit wave with 8 kHz, mono) and the MR. I start the conversion, the green thing runs to the right, but after that, it doesn\'t finish. What to do?
• Try to use Total Recorder or Winamp for the conversion. I know it is strange but some converters (like the Sound Recorder of Windows) do not make the 16 bit wave conversion with 8 kHz correctly. If this also fails try using English file names and paths. (ex. C:\\input.wav)

• When I am trying to convert a file an error window appears saying "converter.exe has encountered a problem and needs to close. We are sorry for the inconvenience.". What to do?
• You probably tried to convert a file that its file name or path contains non-english characters. Try to use a simple path like C:\\Audio.amr .

• How can I play AMR files on my PC?
• We suggest you to use our fast and easy Mobile 3GP player to play your AMR or 3GP files. By installing and using an AMR decoder on you PC. The most popular AMR decoder is SPOT xde Player form VoiceAge. You can also use Apple Quick Time 6.4 and above to play AMR files, download it from the Apple web site.

• The AMR quality is really bad! Can I do something to change this?
• The AMR codec is a speech codec. Therefore, if you convert a music file into AMR the quality wont be very good. The only thinkg you can do to improve the quality, is to select a higher bit-rate.

• When I try to make a conversion the following message shows up: "Windows\\system32\\autoexec.nt. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose \'Close\' to terminate the application."
• The "autoexec.nt" is a critical Windows file. You should reinstall the Windows or copy the file from your Windows installation CD. Just follow the instructions from here.

• What is an SP file?
• SP files are archive files that are used to save several Wave files. You can store and extract wave files in a SP file with MobileAMRconverter.

• What is AMR?
• It is a codec offering a wide range of data rates, which was developed by the European Telecommunications Standards institute (ETSI). The AMR codec is standardized for GSM, and is also chosen by the Third Generation Partnership Project (3GPP) as the mandatory codec for third generation systems. The philosophy behind AMR is to lower the codec rate as the interference increases and thus enabling more error correction to be applied. The AMR codec is also used to harmonize the codec standards amongst different cellular systems.

• Is Mobile AMR converter faster or better than Sony Ericsson AMR converter?
• The Mobile AMR converter is just a GUI of Sony Ericsson AMR converter, that is offering a user-friendlier and easier-to-use environment than Sony Ericsson AMR converter\'s MS-DOS command line interface. Therefore, Mobile AMR converter has the same conversion performance, speed, and quality as the Sony Ericsson AMR converter 1.2.
