LIMITED OUTPUT LEVEL BASED LOUDNESS AMPLIFYING APPARATUS AND CONTROLLING METHOD THEREOF

摘要

An electronic device is disclosed. The electronic device scales an audio signal based on a user volume according to an audio output unit and a user input, and reduces a signal level of an audio signal whose signal level is equal to or greater than a preset threshold level among the scaled audio signals to obtain the scaled audio signal. Compresses and amplifies the compressed audio signal by increasing the signal level of the entire compressed audio signal within a range not exceeding the maximum output level of the audio output unit, and controls the audio output unit to output the amplified audio signal. .
