MP3 File Type

The MP3 file extension stands for MPEG-3 Audio Layer 3. MP3 is a type of compressed digital audio file format that can be played on many different types of media players and other devices that support audio playback. The MP3 audio format uses the MPEG-1 or MPEG-2 encoded audio, which is then encoded using a lossy compression technique to reduce the file size by 50–60% depending on the quality chosen and the encoder's settings. MP3 files usually have a bitrate between 128–320 kbps and average duration of 4-8 minutes per track.

AMR File Type

Adaptive Multi-Rate Codec (AMR) is a standard audio compression format for both speech and music. AMR files use a .AMR file extension and the file format was standardized in 1994 by the European Telecommunications Standards Institute (ETSI). It was designed to allow for multi-rate encoding, which allows it to be more space-efficient than formats such as MP3, which only work on a single rate. This AMR file extension is an audio file type that uses Adaptive Multi-Rate (AMR) technology to reduce bandwidth usage when transmitting voice data over networks. This type of audio data is mostly used in internet phone calls. The Extension is also used in recorded voice messages sent through email or text messages on cellular phones.
