Abstract
A method of processing an audio signal comprising a plurality of audio samples, the method comprising: receiving an audio sample of the plurality of audio samples; on determining that a peak amplitude of the audio sample falls outside a threshold range: suppressing the audio sample to within the threshold range by applying a strictly increasing non-linear function to the audio sample; and outputting the suppressed audio sample; and on determining that the peak amplitude of the audio sample falls within the threshold range or is equal to an upper or lower limit of the threshold range: outputting the received audio sample.
