Abstract:
A sound signal processing apparatus includes: first amplifier which amplifies a sound signal, depending on an input level of the sound signal; and second amplifier which amplifies with a gain the sound signal amplified by first amplifier. Second amplifier automatically decreases the gain when a level of the sound signal is greater than an upper limit threshold, and second amplifier automatically increases the gain when the level of the sound signal is lower than the upper limit threshold and when the gain is lower than a predetermined value. When second amplifier increases the gain, second amplifier changes the gain at a first speed when a user has performed an operation to decrease the input level, and second amplifier changes the gain at a second speed lower than the first speed when the user has not performed the operation to decrease the input level.

Claim (Index 1):
A sound signal processing apparatus comprising:\n a first amplifier which amplifies a sound signal having been input, depending on an input level of the sound signal; and a second amplifier which amplifies the sound signal amplified by the first amplifier with a gain, wherein when a level of the sound signal amplified by the first amplifier is greater than an upper limit threshold, the second amplifier automatically decreases the gain, and when the level of the sound signal amplified by the first amplifier is smaller than the upper limit threshold and the gain is lower than a predetermined value, the second amplifier automatically increases the gain, and wherein when the second amplifier increases the gain, the second amplifier changes the gain at a first speed when a user has performed an operation to decrease the input level, and the second amplifier changes the gain at a second speed lower than the first speed when the user has not performed the operation to decrease the input level.
