Apparatus and Method for selecting one of a First and a Second algorithm Coding Coding algorithm

摘要

An apparatus for selecting one of a First Encryption algorithm that has a First characteristic and a Second Encryption algorithm that has a Second feature to encode a portion of an audio signal to obtain a codified version of the portion of the A series of audioIncludes a First Estimator to estimate a measure of Quality for the first portion of the audio signal, which is associated with the first Encryption algorithm, without actually encode and decode the portion of the audio signal using the first Encryption algorithm.A Second Estimator to estimate a measure of Quality for the second portion of the audio signal, which is associated with the second Encryption algorithm, without actually encode and decode the portion of the audio signal using the second Encryption algorithm.The Apparatus includes a Controller to select the first or the second Encryption algorithm Encryption algorithm based on a comparison between the first and the second as a quality measure of quality.
