Abstract
An audio encoder (100) for encoding audio samples, comprising a first time domain aliasing introducing encoder (110) for encoding audio samples in a first encoding domain, the first time domain aliasing introducing encoder (110) having a first framing rule, a start window and a stop window. The audio encoder (100) further comprises a second encoder (120) for encoding samples in a second encoding domain, the second encoder (120) having a different second framing rule.; The audio encoder (100) further comprises a controller (130) switching from the first encoder (110) to the second encoder (120) in response to characteristic of the audio samples, and for modifying the second framing rule in response to switching from the first encoder (110) to the second encoder (120) or for modifying the start window or the stop window of the first encoder (110), wherein the second framing rule remains unmodified.
