摘要:
A spatial audio processor for providing spatial parameters based on an acoustic input signal comprises a signal characteristics determiner and a controllable parameter estimator. The signal characteristics determiner is configured to determine a signal characteristic of the acoustic input signal. The controllable parameter estimator for calculating the spatial parameters for the acoustic input signal in accordance with a variable spatial parameter calculation rule is configured to modify the variable spatial parameter calculation rule in accordance with the determined signal characteristic.

摘要:
An apparatus (100) for resolving an ambiguity from a DOA estimate (105) (φ̂ amb ) comprises a DOA estimate analyzer (110) for analyzing the DOA estimate (105) (φ̂ amb ) to obtain a plurality (115) of ambiguous analysis parameters (φ̃ I ...φ̃ N ; f(φ̃ I )...f(φ̃ N ); f enh,I (φ̂ amb )....; f enh,N (φ̂ amb ); g p (φ̃ I )...g p (φ̃ N ); D(φ̃ I )...D(φ̃ N )) by using a bias information (101), the bias information (101) representing a relation (φ̂ φ) between a biased (φ̂) and an unbiased DOA estimate (φ), and an ambiguity resolver (120) for resolving the ambiguity in the plurality (115) of ambiguous analysis parameters (φ̃ I ...φ̃ N ; f(φ̃ I )...f(φ̃ N ); f enh,I (φ̂ amb )....; f enh,N (φ̂ amb ); g p (φ̃ I )...g p (φ̃ N ); D(φ̃ I )...D(φ̃ N )) to obtain a non-ambiguous resolved parameter (φ̃ res ; f res , 125).
