Resample AMR

AMR MP3 Converter resamples AMR files by different bit rates. The software also supports more than 90 audio and video files and batch resampling.

1. Download AMR MP3 Converter from the following link, and then install the software
   Download Link: http://www.amr-mp3.net/download/amr_mp3_converter.exe
   
   
2. Launch AMR MP3 Converter
3. Choose AMR Files
   
   
   Click "Add Files" to choose AMR files and then add them to conversion list.
   
   
   Choose one or more AMR files you want to convert and then click Open.
   
   
4. Set AMR Encoding Parameters
   
   
   Click "Options"
   
   
   
   Switch to tab "AMR Options." At Encoding Parameters section, you can set the bit rate and enable/disable DTX (Discontinuous Transmission). In general the bigger the bit rate are, the better the quality is.
   
   The converter accepts the following bit rates: 4.75 kbps, 5.15 kbps, 5.9 kbps, 6.7 kbps, 7.4 kbps, 7.95 kbps, 10.2 kbps, and 12.2 kbps.
   
   The Discontinuous transmission (DTX) is a method of momentarily powering-down, or muting, a mobile or portable wireless telephone set when there is no voice input to the set. This optimizes the overall efficiency of a wireless voice communications system. In a typical two-way conversation, each individual speaks slightly less than half of the time. If the transmitter signal is switched on only during periods of voice input, the duty cycle of the telephone set can be cut to less than 50 percent. This conserves battery power, eases the workload of the components in the transmitter amplifiers, and reduces interference. For more information about DTX, please click here.
   
   Click OK when set is done.
   
   
5. Choose "to AMR"
   
   
   
   
6. Resample AMR
   
   
   Click "Convert" to resample AMR files.
   
   
   The software is resampling AMR files.
   
   
7. Play & Browse
   
   
   When conversion completes, you can right-click converted item and choose "Play Destination" to play the destination file; or choose "Browse Destination Folder" to open Windows Explorer to browse the destination file.

What is AMR?
Adaptive Multi-Rate (AMR) is an audio data compression scheme optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1998 and is now widely used in GSM and UMTS. It uses link adaptation to select from one of eight different bit rates based on link conditions. AMR is also a file format for storing spoken audio using the AMR codec. Many modern mobile telephone handsets will allow you to store short recordings in the AMR format.
