The embodiment of the present invention provides the player method of a kind of audio signal, refer to Fig. 1, and it is that the present invention is real
Execute the schematic flow sheet of the player method of the audio signal that example is provided, as it can be seen, the method include with
Lower step:
S101, it is thus achieved that the characteristic parameter of audio signal.
Concrete, for the audio signal play in audio signal to be played in client or client,
Client can obtain the characteristic parameter of this audio signal.
In the embodiment of the present invention, the method for the characteristic parameter that client obtains audio signal can include but not limited to:
First, client carries out analog-to-digital conversion process to simulated described audio signal, digitized to obtain
Audio signal.
Wherein, described simulated audio signal can include but not limited to Advanced Audio Coding (Advanced
Audio Coding, AAC) audio signal of form or the audio signal of MP3 format.
Such as, client can be, but not limited to utilize pulse code modulation (Pulse Code Modulation,
PCM) technology, carries out analog-to-digital conversion process to simulated audio signal, to obtain digitized audio signal.
Then, client obtains the characteristic parameter of described audio signal from described digitized audio signal.
It should be noted that digitized audio signal can be carried out at framing by client according to default frame length
Reason, obtains the characteristic parameter of audio signal in each frame length the most successively.Due to audio signal in terms of entirety,
Its characteristic parameter changes over and changes, therefore can not use reason stationary signal characteristic parameter obtain skill
Audio signal is processed by art.It addition, although audio signal has time-varying characteristics, but default at one
Frame length, in 10ms～30ms, its characteristic parameter is held essentially constant, and is metastable, the most permissible
Regard the audio signal in a frame length as a quasi-steady state process, so client is permissible in the embodiment of the present invention
To audio signal, according to the principle of one frame length of a frame length, it is thus achieved that the feature ginseng of the audio signal of each frame length
Number.
In the embodiment of the present invention, the characteristic parameter of described audio signal can include but not limited in following parameter extremely
Few one: zero-crossing rate, mel-frequency cepstrum coefficient (Mel-Frequency Cepstral Coefficients,

Wherein, zero-crossing rate refers to the short-time zero-crossing rate of audio signal, and the audio signal of i.e. one frame passes zero level
Number of times.
Wherein, mel-frequency puts forward based on human hearing characteristic, becomes non-linear corresponding pass with Hz frequency
System.MFCC is then to utilize this nonlinear correspondence relation, calculated Hz spectrum signature.
Wherein, energy information refers to the signal intensity of audio signal.
Wherein, spectrum distribution refers to the distribution curve of frequency of audio signal.
Wherein, rhythm refers to be carried forward relevant factor, such as stress, beat and speed etc. with audio signal.
Wherein, tone Key refers to the position of the tune of audio signal, i.e. pitch.
Such as, the tone Key of audio signal can be c major.
It should be noted that rhythm and tone Key in characteristic parameter can fall according to zero-crossing rate, mel-frequency
Spectral coefficient, energy information and spectrum distribution obtain.
It should be understood that client advances with said method obtains the characteristic parameter of audio signal, and in this locality
Memory element in terminal stores, when needing the characteristic parameter using audio signal, directly from local terminal
Memory element in read.
Or, client can also utilize said method immediately when needing the characteristic parameter using audio signal
Obtain the characteristic parameter of audio signal.
S102, according to the characteristic parameter of described audio signal, it is thus achieved that control parameter.
Concrete, client, after the characteristic parameter obtaining audio signal, needs according further to this audio signal
Characteristic parameter, it is thus achieved that control parameter.
Illustrating, client is according to the characteristic parameter of audio signal, it is thus achieved that the method controlling parameter can include
But it is not limited to:
First, the client memory element in local terminal reads the characteristic parameter and control parameter pre-deposited
Corresponding relation, so, client is obtained with characteristic parameter and controls the corresponding relation of parameter.
Then, client according to the characteristic parameter of the audio signal obtained in S101, and characteristic parameter with
Control the corresponding relation of parameter, mate in the corresponding relation controlling parameter in this feature parameter, with
Obtain the control parameter corresponding to characteristic parameter of audio signal.
It should be understood that a characteristic parameter can obtain corresponding at least one and control parameter.
Such as, characteristic parameter and the corresponding relation controlling parameter can include but not limited to the energy of audio signal
The corresponding relation of the parameter of amount information and flash lamp, the parameter of flash lamp can include but not limited to flash lamp
Light intensity.
The most such as, characteristic parameter and the corresponding relation controlling parameter can include but not limited to audio signal
The corresponding relation of the parameter of rhythm and flash lamp, the parameter of flash lamp can include but not limited to flash lamp
Switching frequency.
The most such as, characteristic parameter and the corresponding relation controlling parameter can include but not limited to audio signal
The corresponding relation of the display parameters of tone Key and screen, the color parameter of screen can include but not limited to
The Show Color of pixel or the display brightness etc. of pixel in screen in screen.
The most such as, characteristic parameter and the corresponding relation controlling parameter can include but not limited to audio signal
The corresponding relation of the vibration parameters of rhythm and vibrating device, vibration parameters can include but not limited to vibration dress
The switching frequency put and/or the frequency of vibration of vibrating device.
The most such as, characteristic parameter and the corresponding relation controlling parameter can include but not limited to audio signal
The corresponding relation of the parameter of rhythm and external equipment, the parameter of external equipment can include but not limited to external
The switching frequency of equipment.
The most such as, characteristic parameter and the corresponding relation controlling parameter can include but not limited to audio signal
Tone Key and the corresponding relation showing content identification.Wherein, display content identification can include but not limit
In display content title, display content local terminal storage position and display content numbering in extremely
Few one.Wherein, display content can include but not limited to pictorial information and/or video information.
S103, during playing described audio signal, according to described control parameter, described to playing
The client place terminal of audio signal is controlled；Or, according to described control parameter, to playing institute
The client stating audio signal carries out showing control, and to playing the client place of described audio signal
