Specific embodiment
Referring to Fig.1, a kind of audio Automatic adjustment method is present embodiments provided, comprising the following steps:
Read the audio signal for obtaining next song that vehicle audio will play；
After carrying out audio attribute parsing to the audio signal for reading acquisition, the first sound corresponding with the audio signal is obtained
Effect mode；
When playing the audio signal, signal adjustment is carried out to the audio signal according to the first audio mode.
Here, next song that vehicle audio will play refer to it is to be played in vehicle audio current play list under
One song, for example, current play list be loop play list when, then be next song in the current list, if currently broadcasting
Emplacing table is shuffle playlist, then is the song of next shuffle.
In the present embodiment, vehicle audio is obtained in the audio for next song that next will be played by reading in advance
After signal, audio attribute parsing is carried out to audio signal, obtains the first audio mode corresponding with the audio signal, so as to
To carry out signal adjustment to the audio signal according to the first audio mode, realize when playing the audio signal of next song
The adjust automatically of the audio mode of vehicle audio, manually adjusts without driver, and audio pattern synchronization may be implemented
It is adjusted in audio signal, realizes the variation synchronous with audio signal of audio effect, improve the experience sense of user.And nothing
It needs driver to manually adjust in driving procedure, improves drive safety.
It is further used as preferential embodiment, the audio attribute includes spectrum distribution, tempo variation, amplitude variation
And/or different frequency range signal ratio, ratio of the different frequency range signal than referring to high frequency, intermediate frequency, low frequency signal.
The underlying attribute of audio signal is frequency, amplitude and phase, the frequency spectrum point that the present embodiment passes through analysis audio signal
The attributes such as cloth, tempo variation, amplitude variation and/or different frequency range signal ratio, can know the specific object of audio signal, thus
It chooses corresponding audio mode to play out, obtains best audio effect.
It is further used as preferential embodiment, after described pair is read the audio signal progress audio attribute parsing obtained,
The step for obtaining the first audio mode corresponding with the audio signal, specifically includes:
Audio attribute parsing is carried out to the audio signal obtained is read, obtains the spectrum distribution of the audio signal, rhythm becomes
Change, amplitude changes and/or different frequency range signal ratio；
According to audio attribute parsing result, the music style of the audio signal is obtained；
Call the audio mode being adapted with music style obtained as the first sound corresponding with the audio signal
Effect mode.
Currently, common music style has the various music styles such as prevalence, allusion, disco, jazz, rock and roll.Wherein flow
For senior middle school's low frequency signal of row music compared with horn of plenty, each frequency range is relatively balanced；The low frequency signal and high-frequency signal of classical music
Less, especially high-frequency signal is less, and spectrum distribution is concentrated mainly on Mid Frequency, between generally 100Hz-10kHz；Taxi
The low frequency of high music enriches compared with high-frequency signal, and especially 100Hz drumbeat low frequency signal below is quite abundant, rhythm jump
Than very fast；Jazz entirety rhythm is more gentle, and intermediate-freuqncy signal is more, and main signal basis frequency spectrum has focused largely on voice frequency range,
100Hz-800Hz or so；Rock music entirety rhythm is very fast, and the metal music of medium-high frequency is more, and low frequency is moderate, the letter of most high-amplitude
It number is distributed between 1kHz-5kHz.Therefore, changed by spectrum distribution, tempo variation, amplitude that parsing obtains audio signal
And/or different frequency range signal ratio, it can be obtained the corresponding music style of audio signal, so that adaptable audio mode be called
Play the audio signal.
Such as in the audio signal of disco music style, low frequency, high-frequency signal rhythm quickly, amplitude is very high, therefore
By to audio signal carry out audio attribute parsing, can obtain audio parsing result be low frequency, high-frequency signal rhythm quickly,
The music style of the very high audio signal of amplitude is disco music style, thus what calling was adapted with disco music style
Audio mode is as the first audio mode corresponding with the audio signal.
The present embodiment passes through spectrum distribution, tempo variation, the amplitude variation of acquisition audio signal and/or different frequency range signal
Than the music style of audio signal can be obtained, to call the audio mode to match with music style, intelligent Matching is best
The automatic adjustment of audio mode may be implemented in sound effect parameters, realizes optimal audio effect, without user carry out artificial judgment with
And it manually adjusts.
It is further used as preferential embodiment, it is described when playing the audio signal, according to the first audio mode to this
Audio signal carries out the step for signal adjustment, specifically:
When playing the audio signal, according to the first audio mode, frequency, amplitude and/or phase are carried out to the audio signal
Position adjustment.
The key property of audio signal is frequency, amplitude and phase, carries out frequency, width to audio signal according to audio mode
After degree and/or phase adjustment, realizes the adjustment of the audio mode of vehicle audio, realize optimal audio result of broadcast.
