AMR is a file format for storing spoken audio using the AMR codec. Many modern mobile telephone handsets can store short audio recordings in the AMR format. However, AMR is a speech format and is unlikely to give ideal results when converted to other audio formats.
M4R - is a digital multimedia container format used to store audio in mono channel mode. For example, the Apple iPhone uses MPEG-4 audio files (with .m4r extension) for its ringtones. The length of the m4r ringtone must be up to 40 seconds. M4R and M4A formats shares many similar features.
