.G726 File Extension

A G726 file is an audio file saved using the G.726 codec, an audio encoding standard created and maintained by the International Telegraph Union (ITU). It contains audio meant to be transmitted over a phone network. The audio is 8khz ADPCM audio, meant to be transmitted at either 16, 24, 32, or 40 kbit/s.

The ITU is a division of the United Nations responsible for coordinating the world's response to communication technology issues. In 1990, the ITU introduced the G.726 codec. This codec replaced both the G.721 and G.723 codecs, which were previous ITU standards.

The G.726 codec is used primarily to encode audio transmitted over international and wireless phone networks. On occasion, raw G.726 audio is saved in G726 files. These files are uncommon, so most media players cannot play them. However, some audio libraries allow users to play the audio G726 files contain and convert them to more usable formats.

You can use FFmpeg (multiplatform) or libsndfile (multiplatform) to play the audio a G726 file contains.

You can use FFmpeg (multiplatform) or libsndfile (multiplatform) to convert the audio a G726 file contains to other formats. For example, FFmpeg can convert the audio a G726 file contains to many common audio formats, including .MP3, .WAV, .FLAC, and .AAC.
