Description | GSM is broadly used by cellular phones and is intended for storing and recording vocal audio data received during conversations. Originally, GSM was set up for Europe, but now it holds about 90% of the global cellular communication market; its range exceeds 200 countries. GSM uses archiving techniques to achieve optimal file size. In the majority of cases, files cannot boast great sound quality. Since its inception, GSM has used an array of voice codecs to compress 3.1 kHz audio to less than 10 kbit/s. These codecs include Half Rate, Full Rate, Enhanced Full Rate, AMR-narrowband. |

File extension | .MP3 |
Category | Audio File |
Description | MP3 is the most popular audio file type based on MPEG-1 Layer III compression. Its lossy algorithm was developed in 1991. MP3 codes the sound almost with the same quality, as CD (16-bit stereo), providing compression in size 1 to 10 from the original WAF or AIFF tracks. The quality of MP3 seriously depends on the bitrate. It can be 128 - 256 kbps. Higher bitrates are also supported, but they seriously increase the file size. It is supported by all modern hard- and software players. |
