Information about MP3 and GSM file formats

🔸 File format MP3 GSM
🔸 Full name MP3 - MPEG-1 or MPEG-2 Audio Layer III GSM, Global System for Mobile Audio File
🔸 File extension .mp3 .gsm

🔸 Developed by Fraunhofer Institute Unknown
🔸 Type of format Digital audio Audio
🔸 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. GSM is the file extension used for audio files that store solid digital audio data on a computer or mobile device. This file format is generally used by cell phones. The GSM file format was designed particularly for telephone use in Europe and optimized for recording voice audio like any telephonic conversation.
🔸 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. GSM files can be compressed and uncompressed to reduce the size of the file. This is often done by using lossy compression. The data can be a raw bitstream in an audio coding format. However, it is generally rooted in an audio data format or a container format with a defined storage layer.
