A low-complexity, high-performance vector quantization technique for medium-to-high-bit-rate encoding based on multistage (residual) VQ is introduced. The design, a variable-rate version of multistage VQ, is the vector extension of the piecewise uniform scalar quantizers of P.F. Swaszek and J.B. Thomas (1984), and is related to the piecewise uniform VQs of F. Kuhlmann and J.A. Buckview (1988). Examples for the independent Gaussian and Laplacian sources are included
