Abstract:
1. A method for encoding an audio input signal, said method comprising: storing a plurality of predetermined tonal values corresponding to a plurality of predetermined power levels in a first table and a second table; wherein each of said predetermined tonal values includes a first portion corresponding to an integer portion and a second portion corresponding to a decimal portion, wherein said first portion is stored in said first table and said second portion is stored in said second table; receiving a plurality of input values each representative of a power level of a spectral component of said audio input signal at a corresponding frequency sub-band; accessing at least one corresponding tonal value of said plurality of predetermined tonal values; and for each of said plurality of input values, using at least one corresponding tonal value to generate an encoded output signal representative of said audio input signal; wherein said storing a plurality of predetermined tonal values is performed prior to said receiving said plurality of input values.
