A method and apparatus for reducing the computational load of a dual-rate encoding system having a multi-pulse maximum likelihood quantization process configured to transmit at a first transmission rate and to search subframes of excitation signals according to a reduced number of gain scale factors; and an algebraic code-excited linear prediction block configured to perform a first correlation threshold test for entry into an embedded signal processing loop and a second correlation threshold test for entry into a previous signal processing loop in which the embedded signal processing loop is embedded to reduce the number of times the previous signal processing loop and the embedded signal processing loop are entered, thereby reducing the computational load of the system. |
