Claim:
1. A method for reconstructing a time/frequency tile of an audio scene with at least one audio object (S n , n=N B +1, . . . , N), which is associated with positional metadata ({right arrow over (x)} n , n=N B +1, . . . , N), and at least one bed channel (S n , n=1, . . . , N B ), the method comprising: receiving a bitstream; from the bitstream, extracting a downmix signal (Y) comprising M downmix channels, each of which comprises a linear combination of one or more of the audio object(s) and the bed channel(s) (Y wherein each of the N from the bitstream, further extracting the positional metadata of the audio objects or the downmix coefficients; and reconstructing a bed channel as the corresponding downmix channel after suppressing content representing at least one audio object from the corresponding downmix channel, wherein the suppression is made either on the basis of a positional locator ({right arrow over (z)} wherein the bed channels are reconstructed by suppressing content representing so many audio objects that a signal energy of a remaining content representing audio objects is below a predefined threshold.
