What is I2S used for?

I2S, which stands for Inter-Integrated Circuit Sound, is a digital audio interface commonly used in audio applications. It is specifically designed for efficient transmission of audio data between integrated circuits (ICs) such as digital audio processors, digital-to-analog converters (DACs), and audio amplifiers. The I2S protocol consists of three main lines: Bit Clock (BCLK), Word Clock (WCLK), and Serial Data (SDATA). BCLK synchronizes the transmission of bits, WCLK signifies the beginning and end of each audio sample, and SDATA carries the actual audio data. With I2S, audio signals can be transmitted in a high-quality, precise, and synchronized manner, making it ideal for applications that require accurate audio reproduction, such as audio equipment, digital signal processors, and digital audio interfaces. Its widespread usage in consumer electronics, professional audio systems, and portable devices underscores I2S's significance in the realm of digital audio transmission.
