Abstract
A method for speech equalization, comprising the steps of receiving an input audio signal, processing said input audio signal in dependence on frequency and to providing an equalized electric audio signal according to an equalization function, wherein said equalization function comprises at least an actuator part configured to dynamically applying a compensation filter to the received input signal and dynamically applying a transparent filter to the received input signal, and further transmitting an output signal perceivable by a user as sound representative of said electric acoustic input signal or a processed version thereof.
Claims14
A method for dynamic speech equalization, comprising:
- receiving an input signal,
- processing said input audio signal in dependence on frequency and providing an equalized electric audio signal according to an equalization function, wherein said equalization function comprises at least an actuator part configured to
- applying a first filter to the received input signal, and
- applying a second filter to the received input signal,
- mixing the first output signal from said first filter and the second output signal from said second filter based on a first and second dynamic weights, respective,
- transmitting an output signal perceivable by a user as sound representative of said electric acoustic input signal or a processed version thereof.
A speakerphone comprising
- an input unit for receiving an audio input signal with a first dynamic range of levels representative of a time and frequency variant sound signal, the electric input signal comprising a target signal and/or a noise signal and providing an electric audio input signal;
- a processing unit for modifying said input audio signal in dependence on frequency and for providing an equalized electric audio signal according to an equalization function, wherein said equalization function comprises at least an actuator part comprising:
- a first filter dynamically applied to said received input signal), and
- a second filter dynamically applied to received input signal,
- wherein said actuator part comprises a mixing unit for mixing an output signal from said first filter and an output signal from said second filter based on a first and second dynamic weights, respective
- an output unit for providing an output signal perceivable by a user as sound representative of said electric acoustic input signal or a processed version thereof.
A hearing device comprising:
- an input unit for receiving an audio input signal with a first dynamic range of levels representative of a time and frequency variant sound signal, the electric input signal comprising a target signal and/or a noise signal and providing an electric audio input signal;
- a processing unit for modifying said input audio signal in dependence on frequency and for providing an equalized electric audio signal according to an equalization function, comprising at least an actuator part comprising:
- a first filter dynamically applied to said received input signal, and
- a second filter dynamically applied to received input signal,
- wherein said actuator part comprises a mixing unit for mixing an output signal from said first filter and an output signal from said second filter based on a first and second dynamic weights, respective,
- an output unit for providing an output signal perceivable by a user as sound representative of said electric acoustic input signal or a processed version thereof.
