MID is a sound file format developed by the MIDI Manufacturers Association and is a standard extension for MIDI (Musical Instrument Digital Interface) audio files. Using files of the specified format, the encoding into the standard format of most MIDI data is performed. This standard format is used for the interaction of various devices and programs. The exchange of musical information is between instruments, synthesizers and computers. MID files do not contain the musical data itself, but their attributes - for example, information about how long certain notes sound, or about the pitch, tonality.

3GA is a 3GPP audio file created in 1998. It was created by the 3rd Generation Partnership Project. It is used mainly on mobile devices in order to record, play and transmit audio data. 3GPP (3rd Generation Partnership Project) is a consortium that develops specifications for mobile telephony. The format resembles 3GP files, however, it includes only audio data. In most cases, 3GA files are used by mobile phones in order to record and transmit audio data. For example, this is how audio is recorded in Samsung Galaxy phones. The .3GA file extension can be changed to .3GP, which is widespread. Everything is supported by many programs. The 3GA format uses an adaptive coding audio codec with variable speed (AMR, AMR-NB, GSM-AMR). The development of this codec was done in order to compress encoded speech signals using adaptive modulation. In 1999, the 3GPP consortium adopted the Adaptive Variable Rate Coding (AMR) standard. Currently, it is used by GSM and UMTS communication systems. It is this format for speech recording that has found wide application on mobile devices. We note at the same time that it is not possible to play such files very often on certain devices.
