Method for generating a downward-compatible sound format, in particular a two-channel sound format, with a right channel (R IRT) and a left channel (L IRT) from a multichannel sound format, in particular a five-channel sound format, with the following sound channels: - left channel - right channel - center channel - left rear channel (Ls) - right rear channel (Rs), in which - the level of the center channel is reduced - the center channel with the reduced level is distributed on the left channel by forming a first sum signal (L') - the level of the left rear channel (Ls) is reduced - the left rear channel (Ls) with the reduced level is distributed on the first sum signal by forming a third sum signal, which corresponds to the left channel (L IRT) of the two-channel sound format - the center channel with the reduced level is distributed on the right channel by forming a second sum signal (R'), - the level of the right rear channel (Rs) is reduced - the right rear channel (Rs) with the reduced level is distributed on the second sum signal by forming a fourth sum signal, which corresponds to the right channel (R IRT) of the two-channel sound format, characterized in that in the forming of the first (L') and the second (R') sum signals a dynamic correction of the spectral values of overlapping time windows with k sample values of the left channel and the right channel, respectively, is performed, that in the forming of the third and fourth sum signals a dynamic correction of the spectral values of overlapping time windows with k sample values of the first (L') second (R') sum signals, respectively, is performed, that before each dynamic correction of spectral values of the left channel resp. the right channel, each sum of the spectral values is compared to a target value (A soll, with A soll ∈ R) which follows from the following relationship: A soll, l k = l k 2 + c k 2 A soll, s k = r k 2 + c k 2 in which |l(k)| is the absolute value of a spectral value of the transformed left channel in the complex plane, |c(k)| is the absolute value of the associated spectral value of the transformed center channel in the complex plane, |r(k)| is the absolute value of a spectral value of the transformed right channel in the complex plane, that before each dynamic correction of spectral values of the first (L') resp. second (R') sum signals, each sum of the spectral values is compared to a target value (A soll, with A soll ∈), which follows from the following relationship: A Soll, ls k = lʹ k 2 + ls k 2 A Soll, rs k = rʹ k 2 + rs k 2 in which |r'(k)| is the absolute value of a spectral value of the transformed third sum signals (R') in the complex plane, |l'(k)| is the absolute value of the associated spectral value of the transformed first sum signal (L') in the complex plane, |rs(k)| is the absolute value of a spectral value of the transformed right rear channel (Rs) in the complex plane, |ls(k)| is the absolute value of the associated spectral value of the transformed left rear channel (Ls) in the complex plane, that for the case that the target value (A soll, with A soll ∈ R) is exceeded, the frequency component is added and the absolute sum value resulting therefrom is reduced according to S k = A Soll k + ( A k + B k − A Soll k * n wherein n is a factor larger than 0.1 and smaller than 0.4, and that for the case that the target value (A soll, with A soll ∈ R) is fallen short of, the spectral values of the respective signals to be corrected are multiplied with the following factor (m(k), with): m k = − p + w ⋅ p 2 + A k 4 A k 2 wherein A(k) is the k th spectral value of r', l', l and r, with p = R A k ⋅ R B k + I A k − I B k, B(k) is the k th spectral value of rs, ls and c, with wherein in particular w is a scaling factor in the range of -1 < w < 1, with W ∈ R. -

the level of the left rear channel (Ls) is reduced - the left rear channel (Ls) with the reduced level is distributed on the first sum signal by forming a third sum signal, which corresponds to the left channel (L IRT) of the two-channel sound format -
