Abstract
Technologies are generally described for a system for controlling an audio signal based on a proximity of, e.g., a user's hand to at least one component of an audio control system. In some examples, an audio control system may include a filter configured to provide an echo signal and a control decision unit configured to provide a control signal based on the echo signal.
Claims48
An audio control system, comprising:
- a filter configured to receive a signal from an audio player and to filter the received signal based on a filtering coefficient to provide an echo signal;
- and
- a control decision unit configured to provide a control signal based on at least one of the echo signal and the filtering coefficient.

An audio control system, comprising:
- a first filter configured to receive a first signal from a first speaker and to provide a first echo signal based on the received first signal;
- a second filter configured to receive a second signal from a second speaker and to provide a second echo signal based on the received second signal;
- a control decision unit configured to provide a first control signal based on the first echo signal and to provide a second control signal based on the second echo signal.;
- and
- a controller configured to control at least one functional feature of the first speaker according to at least one of the first and second control signals and at least one functional feature of the second speaker according to at least one of the first and second control signals.
