Improved Frequency Band Extension In An Audio Signal Decoder
Abstract: The invention relates to a method for extending the frequency band of an audio signal during a decoding or improvement process comprising a step of obtaining the decoded signal in a first frequency band referred to as a low band. The method is such that it comprises the steps of: extracting (E402) tonal components and a surround signal from a signal from the low band signal combining (E403) tonal components and the surround signal by adaptive mixing using energy level control factors to obtain an audio signal referred to as a combined signal extending (E401a) the low band decoded signal before the extraction step or the combined signal after the combination step over at least one second frequency band which is higher than the first frequency band. The invention also relates to a frequency band extension device which implements the described method and to a decoder comprising a device of this type.
