Abstract
Tone input device having a tone signal input, a tone signal output and a sound classifier connected to the tone signal input for receiving a tone signal incoming at the tone signal input and for analyzing the tone signal for identifying, within the tone signal, one or several tone signal passages corresponding to at least one condition. Further, the tone input device has a command signal generator connected to the sound classifier for generating a command signal allocated to the at least one condition, and a command output for outputting the command signal to a command processing unit. The sound classifier is configured to interrupt an output of the tone signal via the tone signal output for a duration of the one or several tone signal passages, when the at least one condition exists. A related tone generation device has, in particular, a command processing unit for generating a processed tone signal from the incoming tone signal according to a processing regulation determined by the command signal, up to a cancelling command signal. Respective methods and computer programs are also disclosed.
