CODECSA codec is a type of integrated circuit (IC) that is used to encode and decode digital data, such as audio or video. Codecs are commonly used in electronic devices that process or transmit digital audio or video data, such as smartphones, computers, and TVs. Codecs are typically designed to compress the digital data in order to reduce its size, which makes it more efficient to transmit or store. They also convert the digital data into a form that can be easily processed by other electronic components within a system. Codecs can be implemented in hardware (as an IC) or in software, depending on the application.
