Adaptive Multi-Rate Codec File
| File extension | .amr |
| File category | audio |
| Description | AMR is a compressed file format that functions to enhance speech coding and it consists multiple sampling rates narrow band devices used in encoding or decoding. Recording of AMR files can be done using mobile phones. For video and audio files to play at the same time or accomplish random access memory, one can utilize the 3GPP format. 160 20- millisecond samples embedded in each frame are coded using AMR using ACELP, DTX, VAD and CNG. Recorded AMR files can be converted into other files allowing their use and for them to be distributed. |
| Technical details | AMR has the ability of encoding signals of ranging from 4.75 to 12.2 kbit/s with quality that begins at 7.4 kbit/s.3GPP took up file format in 1999. It is a method that is utilized by GSM and UMTS, it is uses link adaptation to select one of the eight different bit rates. Link adaptation is optimized by AMR with the best codec devices that exist for it to be used by radio channels and capacity requirements. This only works if the connection is good enough to prevent the loss of audio quality. |

WAVE Audio File
| File extension | .wav |
| File category | audio |
| Description | WAV is one of the most common audio formats and stands for Waveform Audio File Format. It is intended for operation with digitalized audio stream. Although it has also been used for non-audio data due to its sampling rate (1 Hz to 4.3 GHz). It contains musical compositions, voice recordings, and various audio effects. Developed by programmers from Microsoft and IBM, it is a key audio format for placing of uncompressed sound files on Windows PCs. The wav wave files can be played back in QuickTime, Windows Media Player, Wav Player and some other programs. In addition to that, they can be processed in audio editing apps. When a file is compressed into WAV, the data are not supposed to be lost, and the quality is excellent. However, the format did not have a huge market share, due to its larger size, as compared with MP3. It is required to have enough time and disc space to upload and send such files via the Internet. One of the major advantages of WAV is linked to the use of Linear Pulse Code Modulation (LPCM) for storage of audio stream. Consequently, a copy is just as good as an original, which is highly appraised by experts in music and professional users. |
| Technical details | Sound files with this extension are recorded into 8 or 16 bit per sample. A standard option for CD Audio is an audio stream of 16 bit per sample and sampling frequency of 44.1 KHz. One second of sound corresponds to 88 Kb of internal memory. WAV files can store metadata in the INFO chunk, and they also include integrated IFF lists. In some cases, the standard format may be used for broadcasting. For instance, BBC stereo data of 44 100 Hz and 16 bit are generally accepted within the VCS system. |
