Abstract:
1. A method of controlling output volume of a signal, comprising: obtaining non-linearity information regarding a non-linear gain curve, the non-linear gain curve indicating a relation between a volume of an input signal and a volume of an output signal; receiving the input signal and target volume information indicating a target volume of the input signal; determining a first gain by using the volume of the input signal and the target volume information; determining a second gain from one of a) the volume of the input signal and the target volume information or b) the first gain, by using the non-linear gain curve; and adjusting the volume of the input signal by applying the second gain to the input signal, wherein the non-linear gain curve is a modified linear gain curve generated by using the non-linearity information including at least one of a maximum compressing volume and a minimum compressing volume, and wherein the linear gain curve is generated by using at least one of volume compressor strength information, volume expander strength information, and the target volume.
