System for tuning audio processing features and method thereof

An audio tuning method of an audio tuning system, the audio tuning method comprising:

• providing a test signal to a reference device;
• acquiring a result of audio processing in response to the test signal from the reference device;
• providing the test signal to a target device;
• acquiring a result of audio processing in response to the test signal from the target device;
• and
• tuning the target device, the tuning comprising comparing the results of audio processing at the reference device and the target device, and adjusting an audio processing characteristic value of the target device to match an audio processing characteristic value of the reference device,
• wherein the test signal comprises a plurality of test signals regenerated with respect to respective audio processing blocks in accordance with test signal information, and
• wherein when the target device has a plurality of audio processing blocks, providing the test signal comprises providing the target device with the plurality of test signals, acquiring the result comprises acquiring results of audio processing in response to the plurality of test signals at the plurality of audio processing blocks of the target device, tuning the target device comprises comparing the acquired results of audio processing and adjusting, in a stepwise manner, audio processing characteristic values of the plurality of audio processing blocks of the target device, based on a result of the comparing.

An audio tuning system comprising:

• an interface configured to provide a test signal to a reference device and a target device;
• a controller configured to receive a first result of audio processing of the test signal at the reference device and a second result of audio processing of the test signal at the target device, compare the first result with the second result, and adjust an audio processing characteristic value of the target device based on a result of the comparison;
• and
• a storage configured to store test signal information for each of a plurality of audio processing blocks,
• wherein when the target device has a plurality of audio processing blocks, the controller is further configured to provide the target device with the plurality of test signals, acquire results of audio processing in response to the plurality of test signals at the plurality of audio processing blocks of the target device, compare the acquired results of audio processing, and adjust, in a stepwise manner, audio processing characteristic values of the plurality of audio processing blocks of the target device, based on a result of the comparing.
