Title:
SOUND SIGNAL RECORDING APPARATUS
Document Type and Number:
Japanese Patent JP3861742
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sound signal recording apparatus having features of both sound signal recording apparatuses of a feedback system and a feedforward system.
SOLUTION: The sound signal recording apparatus includes: a first level control means 8 for controlling a level of a first or second sound signal; a level detection means 10 for detecting a level of a low frequency component of the first and second sound signals obtained from the level detection means 10; and a level control signal generating means for generating a level control signal in response to a level difference of the sound signals respectively obtained from the level detection means 10 and the second level control means 11, a level control signal from the level control signal generating means controls the first and second level control means 8, 11 to eliminate the level difference between the first and second sound signals.
