Claim of US Patent No. 10,924,078
14. A method of declipping a clipped audio signal that has been clipped by a dynamic range control, DRC, model, the method comprising:receiving the clipped audio signal;
determining parameters of the DRC model that have been used for clipping the clipped audio signal;
increasing the dynamic range of the clipped audio signal based on the determined parameters of the DRC model,
wherein the DRC model is a soft-knee DRC model or a hard-knee DRC model and is defined by a control value that is applied to an envelope of an input audio signal; and
wherein the control value comprises a constant gain portion and a variable gain portion.
