A present disclosure relates to a stamp for applying to a surface. The stamp includes a stamp type unit. The stamp type unit includes a die bracket, a first elastic element, a second elastic element, and a bearing bracket. The bearing bracket includes a type band and operatively associated with the first elastic element, the second elastic element and the die bracket. The first elastic element and the second elastic element are disposed between the die bracket and the bearing bracket in a manner that the type band is level with respect to the surface.

A method is provided for extending the frequency band of an audio signal during a decoding or improvement process. The method includes obtaining the decoded signal in a first frequency band, referred to as a low band. Tonal components and a surround signal are extracted from the signal from the low-band signal, and the tonal components and the surround signal are combined by adaptive mixing using energy-level control factors to obtain an audio signal, referred to as a combined signal. The low-band decoded signal before the extraction step or the combined signal after the combination step are extended over at least one second frequency band which is higher than the first frequency band. Also proved are a frequency-band extension device which implements the described method and a decoder including a device of this type.
