The embodiments of the present disclosure provide a method for audio mixing. At least two audio input signals are obtained. Then the at least two audio input signals are linearly superimposed. A mixed signal obtained by linearly superimposing the at least two audio input signals is divided into at least two audio mixing signal-intensity zones according to an audio intensity of the mixed signal. Audio intensity scalability is performed for respective audio mixing signal-intensity zones using corresponding scalability ratios. The at least two audio mixing signal-intensity zones after performing the audio intensity scalability is superimposed and output. The embodiments of the present disclosure further provide an apparatus for audio mixing.
