What is a .G723 file?
A .G723 file is a type of audio file that uses a special way to store sound called the G.723 codec. This codec is a set of rules for compressing and decompressing audio, specifically designed by an organization called the International Telegraph Union (ITU). The main purpose of this kind of audio file is to hold spoken words, like a conversation or a speech, so it can be sent over the internet or other networks smoothly.
The audio inside a G723 file is formatted in a way known as 8khz ADPCM audio. This means the sound is recorded at a quality that captures enough detail for voice but not as high as what you might want for music. The "8khz" part refers to the sample rate, which is a measure of how many times the audio is measured or sampled per second. In this case, 8,000 times per second. ADPCM stands for Adaptive Differential Pulse Code Modulation, a technique used to compress the audio data so it can be sent more easily over a network. The G.723 codec can compress the audio to be sent at two different speeds: either 24 or 40 kilobits per second (kbit/s), depending on how much data you want to use.
To open a .G723 file, you can use programs like FFmpeg or libsndfile. FFmpeg is a very powerful tool that can work with a wide range of audio and video formats, including G.723 files. It's a bit complex but very versatile. libsndfile is another program that can open these files, and it's specifically designed to work with various audio formats. Both of these programs can help you play, convert, or manipulate G.723 audio files in different ways.
