Classification: CPC G | IPC G

Claim 13:
14. An apparatus comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the apparatus to:
determine, based on a time domain waveform of a piece of music to be played, a characteristic of the piece of music to be played;
input the characteristic into a transparency probability neural network to obtain a transparency probability of the piece of music to be played;
determine a mapping relationship between the transparency probability and a transparency enhancement parameter by:
performing a plurality of transparency adjustments on a nontransparent piece of music with a transparency probability, wherein transparency enhancement parameters corresponding to the plurality of transparency adjustments are: p+Δp*i, i=0,1,2 . . . in order;
determining a plurality of subjective perceptions t(i) corresponding to the transparency adjustments based on scores that are determined by comparing a sound quality of a piece of music adjusted according to the transparency enhancement parameter p+Δp*i with a sound quality of a piece of music adjusted according to the transparency enhancement parameter p+Δp*(i−1) by a set of raters; and
determining the mapping relationship based on a magnitude of t(i);

determine the transparency enhancement parameter corresponding to the transparency probability based on the mapping relationship between the transparency probability and the transparency enhancement parameter; and
perform, based on the transparency enhancement parameter, transparency adjustment on the piece of music to be played.
