Abstract:
1. A method comprising: after a switch from a second coder mode to a first coder mode of an encoder activating at least one selection rule in response to having received for said first coder mode at least as many sections of an audio signal as are covered by an analysis window, wherein at least said first coder mode and said second coder mode are available for encoding a specific section of said audio signal, wherein at least said first coder mode enables a coding of a specific section of said audio signal based on at least two different coding models, and wherein in said first coder mode a selection of a respective coding model for encoding said specific section of an audio signal is enabled by said at least one selection rule which is based on signal characteristics, which signal characteristics have at least partly been determined from said analysis window, which analysis window covers at least one section of said audio signal preceding said specific section; and encoding said audio signal using said first coder mode, resulting in an encoded audio signal.
