An audio tuning system including: an interface configured to provide a test signal to a reference device and to a target device; and a controller configured to acquire a result of audio processing in response to the test signal from the reference device and a result of audio processing in response to the test signal from the target device; compare the results; and adjust an audio processing characteristic value of the target device to match that of the reference device based on a result of the comparison. The audio tuning system may automatically tune the audio characteristic of the target device to match the reference device.

System for tuning audio processing features and method thereof

A method and an apparatus for designing a sound compensation filter of a portable terminal are provided. The method includes synchronizing a signal input through a microphone of the system and a test signal, estimating a loss interval of the synchronized signal, compensating for a frame signal delayed by a signal loss in a time axis when the signal loss of the estimated loss interval is greater than a threshold and restoring the loss interval of the signal.
