VOICE SINGAL REMOVING CIRCUIT

PURPOSE:To simplify the circuit and obtain sufficient compensation effect by composing the circuit of a low-order filter when a musical sound signal which is canceled together with a vocal and not the vocal of center localized recording is compensated. CONSTITUTION:An LPF 6 and an HPF 7 are provided for compensating signal extraction, and an inverter 10 inverts only the passing signal of the LPF 6 to make its phase relation opposite from the passing signal of the HPF 7. A 2nd adder 8 adds both the signal in the opposite phase relation together to make signals in the vocal band remaining in the filter passing signals cancel each other, and thus secure an attenuation quantity, so even when the circuit is composed of the low-order filter, the compensating signal which provides sufficient compensation effect can be extracted.
