What is a G723 file?
A G723 file is an audio file saved using the G.723 codec, an encoding algorithm created by the International Telegraph Union (ITU). It likely contains spoken audio meant to be transmitted over a network. The audio G723 files contain is 8khz ADPCM audio, meant to be transmitted at either 24 or 40 kbit/s.
More Information
G.723 is one of several ADPCM audio standards created by the ITU, which is a communications technology-oriented division of the United Nations. It is related to both the G.721 standard and the G.726 standard, which also describe codecs used to transmit spoken audio over a network. G.726 is the newest of these standards; it replaced both the G.721 and G.723 standards.
Primarily, the G.723 audio was used to encode audio transmitted over international or wireless phone networks. So, a G723 audio file likely contains audio spoken during a phone conversation.
How to open a G723 file
You can use FFmpeg (multiplatform) or libsndfile (multiplatform) to play the audio a G723 file contains.
