Information about MP3 and AMR file formats
| Name | MP3 | AMR |
| Full name | MP3 - MPEG-1 or MPEG-2 Audio Layer III | AMR - Adaptive Multi-Rate |
| File extension | .mp3 | .amr, .3ga |
| MIME type | audio/mpeg, audio/MPA, audio/mpa-robust | audio/amr |
| Developed by | Fraunhofer Institute | 3GPP |
| Type of format | Digital audio | Audio compression format |
| Description | MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. | The Adaptive Multi-Rate (AMR or AMR-NB or GSM-AMR) audio codec is an audio compression format optimized for speech coding. AMR was adopted as the standard speech codec by 3GPP in October 1999 and is now widely used in GSM and UMTS. |
| Technical details | Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source. | AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband (200-3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s. Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200-3400 Hz. |
