Embodiment Construction

[0022] Please refer to figure 1 , is a schematic diagram of an audio adjustment system 1 according to an embodiment of the present invention. The audio adjustment system 1 includes: a first test module 100 , an analysis module 106 , an equalizer module 108 , a second test module 110 , a voice playback device 102 to be tested, and a sound receiver 104 .

[0023] Wherein, the first test module 100 , the analysis module 106 , the equalizer module 108 and the second test module 110 can be operated by an application program stored in a host 10 to execute an audio adjustment method.

[0024] The first test module 100 is used for generating a frequency response test signal 101 . In one embodiment, the frequency response test signal 101 is a chirp signal (Chirp Signal), which means a section of signal from low frequency to high frequency gradually. In one embodiment, the audio playback device 102 to be tested further includes an audio processing module 112 . The sound processing mo...

Abstract

The embodiment of the invention discloses an audio frequency adjusting system and an audio frequency adjusting method. The audio frequency adjusting method comprises the following steps of: outputting a frequency response test signal to a to-be-tested voice broadcasting device; receiving a first output audio frequency which is generated by the to-be-tested voice broadcasting device according to the frequency response test signal; performing response analysis on the first output audio frequency to generate a group of equalizer parameter suggested values; adjusting a group of equalizer parameters according to the equalizer parameter suggested values so that an original sound signal generates a sound test signal according to the equalizer parameters; instantaneously generating a second output audio frequency through the to-be-tested voice broadcasting device according to the sound test signal; judging whether the auditory effect of the second output audio is close to the original sound signal or meets the demand of user; and adjusting the equalizer parameters if the auditory effect is not close to the sound test signal or does not meet the demand of user. The audio frequency adjusting system and method disclosed by the embodiment of the invention can adjust audio frequency fast to achieve the purpose of conforming to the auditory effect.

Description

technical field [0001] The invention relates to a system and method for electronic digital data processing, in particular to an audio frequency adjustment system and method. Background technique [0002] In modern technology, many devices or toys are equipped with devices that can send voices to prompt operators, play music or allow children to hear the sounds from the toys. In the design process of these devices or toys, it is often necessary to burn / download the sound sample signal to the audio processing chip so that the audio playback device to be tested, such as a speaker, can test whether the auditory effect of the actually played sound is It meets the needs, and when you feel that it does not match, adjust the sample signal of the sound and then burn / download it again, and play it again to determine whether the auditory effect meets the need. Such an adjustment method does not have a reference sample that can be used as a benchmark, and can only be adjusted repeatedl...
