What is M4A?
MPEG-4 Audio. Because of its exceptional performance and quality, Advanced Audio
Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is
the audio codec of choice for Internet, wireless and digital broadcast arenas.
AAC provides audio encoding that compresses much more efficiently than older formats,
such as MP3, yet delivers quality rivaling that of uncompressed CD audio.
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.
