Abstract
A method, system and computer program product for computationally efficient estimation of the scale factors of one or more frequency bands in an encoder. These scale factors are dependant on a plurality of variables. One of the variables is approximated according to embodiments of the invention. This reduces the complexity of the estimation of scale factors, especially in digital signal processors.
