Non-Uniform Quantization

Non-uniform quantization is a method of converting a range of continuous, varying signal values into smaller, discrete levels, but unlike uniform quantization, these levels are spaced unevenly. This means more levels are allocated to more important or frequently occurring parts of the signal—like loud sounds—while less critical areas receive fewer levels. This approach helps preserve the quality and detail of the original signal while reducing data size, making it more efficient for compression and processing, especially in audio and multimedia applications.
