perceptual coding

Perceptual coding is a technique used in audio and video compression that takes advantage of how our senses perceive sound and images. It focuses on removing data that is less noticeable to us, allowing for smaller file sizes without significant loss of quality. For instance, it may reduce sounds that are too quiet compared to louder ones or eliminate fine details in images that our eyes can’t easily detect. This helps in delivering high-quality media at reduced storage requirements, making streaming and storage more efficient while maintaining an enjoyable experience for users.
