Claim 2:
3. The method according to claim 1, wherein the inter-frame energy fluctuation parameter represents a ratio of total energy of the first downmixed signal and the first residual signal to total energy of a second downmixed signal and a second residual signal of a previous frame of the second target frame, or the inter-frame energy fluctuation parameter represents a difference between total energy of the first downmixed signal and the first residual signal and total energy of the second downmixed signal and the second residual signal;
the inter-frame energy fluctuation parameter represents a difference between a logarithm of total energy of the first downmixed signal and the first residual signal and a logarithm of total energy of the second downmixed signal and the second residual signal;
the inter-frame energy fluctuation parameter represents a ratio of energy of the first downmixed signal to energy of the second downmixed signal, or the inter-frame energy fluctuation parameter represents a difference between energy of the first downmixed signal and energy of the second downmixed signal;
the inter-frame energy fluctuation parameter represents a difference between a logarithm of energy of the first downmixed signal and a logarithm of energy of the second downmixed signal;
the inter-frame energy fluctuation parameter represents a ratio of energy of the first residual signal to energy of the second residual signal, or the inter-frame energy fluctuation parameter represents a difference between energy of the first residual signal and energy of the second residual signal; or
the inter-frame energy fluctuation parameter represents a difference between a logarithm of energy of the first residual signal and a logarithm of energy of the second residual signal.
