Intel Smart Sound Technology (Intel SST) for I2S Audio is a technology designed to enhance the audio experience on Intel-based systems by providing high-quality audio processing and efficient communication between audio devices (like microphones, speakers, and sound cards) and the CPU. Intel SST is often used in devices with I2S (Inter-IC Sound) interfaces, which are commonly found in modern laptops, desktops, and embedded systems. This technology enables features like advanced noise cancellation, improved voice recognition, and lower power consumption during audio processing.
