| File extension | .AMR |
| Category | Audio File |
| Description | The AMR format uses a speech coding pattern, which is now applied in the GSM system. It encodes compressed spoken audio data and uses multi-rate codecs, such as DTX, ACELP, CNG and VAD. There are eight bitrate values for AMR, ranging from 4.75 kb/s to 12.2 kb/s. This structure allows the codecs to create a group of 160 twenty-millisecond-long samples within a frame. AMR files can be played in a number of Windows-based media players, as well as mobile devices, such as Android, Apple, etc. Most users prefer to convert AMR tracks to MP3, WMA, etc. tracks. |

| Category | Audio File |
| Description | MP4 files can contain video and sound data. It is a file container that supports different multimedia content types such as multiple audio streams, subtitles, 2D and 3D image frames. MP4 is also used for streaming media services (online or digital TV). This file type supports the control of transmission speeds for media signal, as well as correcting corrupted frames. Thanks to comparatively low system requirements, MP4 is now the most popular container type for sharing media. |

AMR voice memos recorded on a phone play on almost nothing outside that phone. Converting AMR to MP4 (M4A audio in an MPEG-4 container) gives you a file that works in iTunes, Windows Media Player, every web browser, and every mobile platform. Drop your .amr file above.
AMR (Adaptive Multi-Rate) is the audio codec used on virtually all mobile phones for voice calls and voice memos. The .amr file extension indicates narrow-band AMR (4.75–12.2 kbps, 8 kHz sample rate). AMR-WB (Wideband) extends that to 23.85 kbps at 16 kHz. The codec optimises for intelligible speech, not music, so background sounds, instruments and wide-spectrum audio are reproduced poorly. Outside of mobile platforms, AMR has almost no native playback support.
When used as an audio container, MP4 (technically M4A) wraps AAC audio in an MPEG-4 Part 12 file. AAC is the successor to MP3: at the same bitrate it sounds noticeably better, especially below 160 kbps. MP4/M4A is natively supported on iOS, Android, macOS, and in all major browsers. It is the default export format for iTunes, Apple Music, and many other streaming and editing tools. Car stereos and portable players have supported M4A since roughly 2008.
