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.

In some embodiments, a stamp may comprise at least one stamping component and one stamping insert. The stamp component may be formed of a top a bottom part with a cushion-receiving element. The stamping insert may be connected so as to move synchronously via a reversing mechanism having a slide track in the bottom part via an shaft or trunnion to the top part. In the resting position a text plate mounted on the stamping insert may abut against an ink pad in the cushion receiving element, and that in a stamping process the stamping insert with the text plate can be shifted by the reversing mechanism into a stamping position. At least the text plate carrier and/or the mounted band unit or date unit, may be positioned to be replaceable with the shaft or the trunnions or stub shafts, respectively. The system may include a stamping insert.

In some embodiments, a stamp with metallic elements, may comprise at least one stamping component and one stamping insert. The stamping component may be formed of a top part with a handle element and a bottom part with a cushion-receiving element. The stamping insert may be connected so as to move synchronously via a reversing mechanism having a slide track in the bottom part via a shaft or trunnion to the top part. In the resting position a text plate mounted on the stamping insert may abut against an ink pad soaked with ink in the cushion-receiving element. The metallic elements can be attached from the outside onto the top and bottom parts formed from plastic material and these are fixed via a fastening system of the upper and lower parts. The metal part of the bottom part is fixed on a surface of the plastic part.

The invention describes a stamp (1) and stamp pad (130) for a self-inking stamp (1), wherein in a housing (131) or a carrying device (11) at least one pad for absorbing ink is arranged. The carrying device (11) is formed rectangular in shape from a base plate (135) with longitudinal surfaces (136) and lateral surfaces (136) moulded thereon, wherein on two surfaces running in parallel handle elements (138) for the lateral gripping of the carrying device (11) are arranged. Preferably means in form of grooves (133), catches and/or elevations (134) for the fixing in a stamp (1) are arranged on the carrying device. On the lateral surface (137) of the carrying device (11) a handle element (138) each for the lateral gripping and pulling of the carrying device (11) out of a stamp (1) formed of a plurality of parts displaceable within one another, wherein the handle elements (138) are formed for insertion in a clearance (139) of a lower part (3) of the stamp (1) and these do not protrude the outer surface (140) of the lower part (3), so that an upper part (2) of the stamp (1) is displaceable via the clearance (139) with the handle elements (138) inserted in the lower part (3).
