Abstract
This signal processing device comprises: a control circuit that, in accordance with a parameter relating to a stereo signal, alters a weighting coefficient based on the amplitude of the cross spectrum of the stereo signal; and a detection circuit that detects the inter-channel time difference of the stereo signal on the basis of the cross spectrum weighted using the weighting coefficient.
Claims9
A signal processing apparatus, comprising:
- control circuitry, which, in operation, alters a weighting coefficient in accordance with a parameter related to a stereo signal, the weighting coefficient being based on an amplitude of a cross spectrum of the stereo signal;
- and
- detection circuitry, which, in operation, detects an inter-channel time difference of the stereo signal based on the cross spectrum weighted with the weighting coefficient.
A signal processing method performed by a signal processing apparatus, the signal processing method comprising:
- altering a weighting coefficient in accordance with a parameter related to a stereo signal, the weighting coefficient being based on an amplitude of a cross spectrum of the stereo signal;
- and
- detecting an inter-channel time difference of the stereo signal based on the cross spectrum weighted with the weighting coefficient.
