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.

Sure. You need to set an option before converting.

1. Click on "Options" and switch to tab "General"
2. Set a number at "Output Volume". The number is described below.
• < 100% - Decrease volume
• = 100% - No changes
• > 100% - Increase volume
For example:

• 50%: Decrease volume to half of original file
• 200%: Increase volume to double volume of original file
3. Convert your file
4. Done

It's easy. Please click "Options" -> "ID3" and then check "Add ID3 tag", and then edit the custom ID3 tag information.

At "Title" field, if you check "Name as file name (not include extension)", AMR MP3 Converter will set Title as file name when converting. For example: original file name is "Happy New Year.mp3", and then the title will be set as "Happy New Year" automatically.

Yes, it is. You may click "Options" -> "Output" tab, choose "Specific folder" at "Output folder" combo-box and then click "Browse" button to choose an output folder.

Yes, it is. Similar to question above, but you should check "Keep original directory tree", thus the software will create folders according to path of source file automatically when converting.

For example: Original file is "C:\Music\pop\test.amr" and output folder is "D:\Output." If the option is checked, the output folder will be "D:\Output\C\Music\pop."

First, split the left channel.

1. Set output channel to mono at target format option
2. Check "L channel" at "Options" -> "General" -> "When converting 2 channels to 1 channel, the output channel equals to"
3. Convert your file

Then, split the right channel, similar to instructions above, just check "R channel" at step 2.
