ABSTRACT:
An efficient finite length POW10 calculation for MPEG audio encoding. A method for encoding an audio input signal includes storing a plurality of predetermined tonal values corresponding to a plurality of predetermined power levels. The method also includes receiving a plurality of input values each representative of a power level of a spectral component of the audio input signal at a corresponding frequency sub-band and accessing at least one corresponding tonal value of the plurality of predetermined tonal values. The method further includes generating an encoded output signal representative of the audio input signal by using at least one corresponding tonal value for each of the plurality of input values. Further, the storing of the plurality of predetermined tonal values is performed prior to the receiving of the plurality of input values.
