Compressed audio files used by most 3G mobile phones carry the .amr file extension. This format developed by Ericsson, can either be narrow band (AMR-NB) or wide band (AMR-NB); the most common is the narrow band. AMR refers to Adaptive MultiRate, a technology which allows the compression rate to be reduced if signal interference increases. The reduced compression results in better error correction performance. The Adaptive MultiRate codec was adopted as the standard speech codec by the 3d Generation Partnership Project (3GPP) in 1998, and later by the European Telecommunications Standards Institute (ETSI) in 1999 and 2006, making it supported almost universally by any mobile communications device.

I really do love FileCure because it's so easy to use - you don't have to be some kind of computer guru to get just what you need!

Plug and play? Not even close. I spent a lot of time trying to get my new, so-called 'plug and play' scanner to work. I was about ready to take it back. ParetoLogic FileCure got it working and saved me a needless trip (and gas!!) back to the store.

I have to admit I'm no computer geek. When something goes wrong, I usually have to call someone to fix it and it costs me a lot of money. When my printer wouldn't work, a friend of mine suggested I try ParetoLogic FileCure a try. I figured it was worth a shot because I was going to have to pay for a geek anyway. I was so happy when it worked... and worked properly!

I figured the graphics card my grandson gave me was broken when I couldn't get it work on my computer. It turns out that I just didn't have the right driver. ParetoLogic FileCure got it workin.

Hello FileCure folks:
I can't thank you enough for this great product. I just bought a new Vista machine and had been having all kinds of problems. First it was my screen and once I got that fixed it was the printer . Finally, my son suggested I try your product. It worked great and continues to keep my computer working. Thanks you.

I hate paying a lot of money for anything. That's why I buy mostly used computer equipment. Last week I thought I got taken when I bought a scanner. It just would not work. ParetoLogic Driver Cure got it working. With the updates, it makes sure my stuff will keep working and that I don't have to pay more money.

I work at a school so my mom thinks I am some kind of computer whiz. I have wasted so much time trying to get her stuff to work. Our IT guy suggested I try ParetoLogic FileCure. It has been a godsend and has saved me a lot of wasted hours. My mom and I can't thank you enough.

My wife bought me a new Vista system, and ever since I have had problems with some of my hardware. I saw FileCure, and decided to give it a shot. Ever since, the Vista and my hardware have been working great. Thanks!

I upgraded my system to Vista, and my printer started to act funny. No error messages, but it just wasn't working quite right. I read that drivers could sometimes be the problem. I looked online and saw FileCure. After downloading FileCure, my printer works great. You guys rock!

The .amr file structure consists of a header of 6 bytes identifying the file as an AMR, followed by the audio data which has been broken up into a specific number of frames. The information in the header is universal and consistent among all .amr files. If the header differs from the standard, the file is most likely corrupt and should not be opened. Each of the frames contains 20ms of audio data which can be encoded at different bit rates, thus distinguishing the file as MultiRate. Each frame also has its own single byte header followed by the raw audio data. AMR technology uses the ACELP (Algebraic Code Excited Linear Prediction) algorithm, specifically designed for compression of the human voice.
Instructions on Using File Cure to Solve Computer Problems
Start Your Free File Scan File Cure Software will scan your computer system to check if any of the file extensions need to be updated.
Scan is Done Once the scan is complete, File Cure will prompt you to update all the file extensions which are outdated and can cause computer errors. Outdated file extensions can cause your software to malfunction.
Official File Extensions Used ONLY Whichever brand of computers you use; Dell, HP, Lenovo, Fujitsu, Acer, Compaq, Gateway etc, File Cure ONLY recommends the correct file extensions for your computer to ensure your computer does not crash.
Finished Updating Your File Extensions All Software Issues should be Solved Once File extensions are Updated and the Computer is restarted.
Why settle for 1 when you can get ALL 5 for the same price?

AMR as applied to VoIP (Voice over Internet Protocol) services allows for extremely high QoS (Quality of Service) results due to the utilization of 8 different bit rates. This flexibility makes it possible for mobile device manufacturers to tailor their software to the conditions and needs of a given market. The technology has proven to be extremely reliable and robust even across multiple languages (US and UK English, German, French, Italian, Spanish, and Mandarin Chinese).
Apple's Quicktime Player and RealNetworks' RealPlayer can both open these files for listening. Users who wish to edit must convert to another format supported by their editing software. Mobile Media Converter is a free conversion program for Windows and Linux, that handles both audio and video conversion using ffmpeg. The program supports many of the common formats like .mp3, .ogg, .wma, .wav, .mpeg, and .3g2. Allok MP3 to AMR Converter, Mobile Ringtone Converter, Mobile AMR converter, FLAC MP3 Converter, and EZ Ringtone are other programs available conversion of .amr files.
Conversion tools are popular among those wishing to customize their cell phones, as they allow users to convert their favorite music or other sound files for use as ringtones. Users should find a conversion tool that works in both directions for this purpose.
Errors related to .amr files are limited due to the nature of the data involved, but they do occur. The most common among them are codec errors when trying to open the files on a computer. While Quicktime and RealPlayer have the AMR codec installed by default, it is not uncommon for these codecs to be damaged or inadvertently removed from a system. Codec errors can be corrected by simply downloading and installing the proper codecs. Some conversion programs also require the AMR codec to be installed on the computer before conversion can take place.
Other errors may occur if the file header does not match the standard header that all .amr files carry. This bad header could be the result of a faulty transmission, an error while using a conversion tool, or just bad coding by a developer. In any case, bad headers do not pose any serious threat to a computer's operating system or crucial data, nor will they render a mobile device inoperable. Users can expect that these files will not be usable on the mobile device and should be replaced, and on the computer they can result in a crash of Quicktime or RealPlayer.
