Abstract

A method and a system for processing audio in a telecommunication system are disclosed. The sampling rate of the audio file is reduced to a pre-specified sampling rate. Thereafter, the frequency of the audio file is adjusted using certain parameters. Then, the amplitude of the audio file is modified so that the average peak amplitude is close to a desired amplitude value. This is followed by hard limiting of the audio file to ensure that peak amplitude never crosses a certain pre-specified value. The processed audio file is then transmitted over the telecommunication network.
