Abstract
A method may include determining that values of a plurality of samples of a digital audio signal that are stored in an input buffer exceed a clipping threshold value. The method may further include identifying the plurality of samples that exceed the clipping threshold value as potentially clipped samples of the digital audio signal. In addition, the method may include generating, based on identification of the potentially clipped samples, attenuated samples by uniformly applying a fixed attenuation factor to the potentially clipped samples and to every sample of the digital audio signal included in the input buffer that follows the potentially clipped samples. Further, the method may include generating a plurality of modified attenuated samples by applying interpolation to the attenuated samples that correspond to the potentially clipped samples. The method may also include outputting the attenuated samples and the modified attenuated samples as a modified digital audio signal.
