Abstract:
1. A sound recording apparatus having a driving unit, comprising: a sound collection unit configured to generate a sound signal from an input sound; a detection unit configured to detect a level of the sound signal; an adjustment unit configured to adjust a level of the sound signal at an amplification factor corresponding to the detected level of the sound signal; a processing unit configured to process the sound signal adjusted by said adjustment unit to prevent a sound signal amplified by said adjustment unit from containing a sound signal generated upon driving the driving unit; and a control unit configured to control driving of the driving unit, said adjustment unit, and said processing unit, wherein said control unit controls said processing unit to replace a sound signal in a predetermined period that begins after instructing driving of the driving unit with a signal calculated from a sound signal included in a first period that begins after the predetermined period has elapsed, and controls said adjustment unit to substantially equalize an amplification factor when driving of the driving unit is instructed and an amplification factor in the first period.
