What is U-law?

U-law is a standard audio compression technique, predominantly used in telecommunication systems. It’s a form of companding, a method that reduces the dynamic range of signals, making them easier to process. U-law is particularly effective in systems where signal noise is a significant issue, as it improves the signal-to-noise ratio. In simpler terms, imagine you’re trying to have a conversation in a noisy room. U-law is like a friend who repeats what you say, but louder and clearer, making it easier for the listener to understand. It’s a crucial tool in ensuring clear, effective communication in noisy digital environments.
