The volume value V1 that user described in the embodiment of the present invention is arranged: for user is to the volume value set by audio-frequence player device; Describedly actually arranging volume value V2, is the final volume value that audio-frequence player device is arranged voluntarily.As connect as described in above-mentioned steps, when the volume value V1 that acquisition active user is arranged and audio volume level are 1, corresponding output power is 0.2W, (and the inclined code audio sound of above-mentioned audio file 1 may be less than normal: audio file 1 output power when volume is grade 1 is how many (if 0.1W), and audio file 1 output power when volume is grade 2 is how many (if 0.2W)).So now search the volume control documents of audio file 1, when the volume value that the user of user interface is arranged is that V1 is as during for 1 grade volume (corresponding 0.2W), the volume (0.2W output) of corresponding displaying audio file 1 should be audio volume level is 2, then control audio-frequence player device arranges final volume value V2 such as the level of sound volume of current broadcasting music is voluntarily 2.
Like this, user, when listening different audio files continuously, there will not be the situation that sound in the process of listening to the music is suddenly big or suddenly small, decreases the frequency that user operation volume adjusting touches the button, provide users with the convenient.
Below by way of a concrete Application Example, the present invention is described in further detail:
This specific embodiment is using mobile terminal as audio-frequence player device.Refer to Fig. 2, Fig. 2 is the specific embodiment process flow diagram of a kind of musical sound control method based on audio-frequence player device of the present invention, and the musical sound control method based on audio-frequence player device described in Fig. 2 embodiment comprises the following steps:
S100, when starting to play a piece of music, first searching the volume control documents whether having this music, if had, performing step S200, if not, perform step S300;
S200, obtain the volume value V1 that active user arranges, in volume control documents, search corresponding actual of this volume value arrange volume value V2, then arranging volume value is V2;
Wherein, the volume value V1 that user is arranged is exactly that user is to the volume value set by mobile terminal; Actually arranging volume value V2, is exactly the volume value that final mobile terminal self is arranged;
In this specific embodiment, described volume control documents, to record corresponding to the various volume values set by user actual in the inside arranges volume, such as mobile terminal loudness has 0 ~ 9 totally ten grades of volumes settings on a user interface, but for different music because himself coding is different, corresponding musical sound volume is set with one-level mobile terminal loudness different, that to be provided with volume be 6 to mobile terminal equally, but sound sounds heavy when music file MUSIC1 plays, when another music file MUSIC2 has play, sound sounds lighter, if actual volume value is set as 5 when being play by MUSIC1, and actual volume value is set as 7 during MUSIC2 broadcasting, then can reach the wave volume effect of user's set volume 6 on a user interface, volume control documents is exactly the file that have recorded above-mentioned corresponding relation, by described in upper example on a user interface mobile terminal loudness have 0 ~ 9 totally ten grades of volumes arrange, then all have a volume control documents to every a piece of music, the inside have recorded user's actual volume of establishing when UI Preferences 0 ~ 9 volume at different levels.
S300, first time play this music file time obtain its volume control documents.
Namely when the audio file that need play does not have volume control documents, first time be the first audio file volume control documents is set time, first play this first audio file and obtain the volume V1 that active user is arranged and the power W1 obtaining the output of audio-frequence player device sound output every a schedule time T, the power W1 that the sound output of the volume V1 that the active user obtained the same time is arranged and correspondence exports is designated as volume V1 and power W1 corresponding relation (V1, W1); Obtain the volume control documents of this first music according to recorded a series of volume V1 and power W1 corresponding relation (V1, W1) when playing this first audio file.
In this specific embodiment, per interval T obtains the volume V1 that active user is arranged, the power W1 obtaining the output of mobile terminal sound output, V1, W1 that the same time obtains are designated as (V1, W1), what deserves to be explained is, (V1, W1) under different time is likely unequal mutually; Then obtain the volume control documents of this song according to recorded a series of (V1, W1) when playing this song; Particularly, comprise the following steps according to the volume control documents obtaining this song according to recorded a series of (V1, W1) when playing this song:
S301, convert all V1 in a series of volume V1 recorded when playing the first audio file and power W1 corresponding relation (V1, W1) to identical volume value.Consider in this specific embodiment that user is in the process playing music, likely adjust volume by user interface, therefore the V1 in a series of (V1, the W1) that obtain may be different, therefore first convert all V1 to identical volume value by a kind of conversion;
This step is actual, and that complete is the power W1 that the mobile terminal sound output of the volume V1 that arranges of known active user and correspondence exports, the power that the mobile terminal sound output obtaining volume that user the arranges correspondence corresponding when other values exports; Such as, known (5, W1) obtains (6, W2) or (8, W3);
How does that change? to explain below.When the source played sound is constant when a certain (namely when playing music the acoustic information inscribed), the power that mobile terminal sound output exports is all then obtain final output power according to the volume settings under user interface through a kind of computing by basic value; As shown in Figure 2:
" source of sound " is exactly need the acoustic information of mobile terminal playing (comprise the coding of volume in this acoustic information, because coding is fixing, therefore the volume that this information comprises itself is fixing);
" base power " is exactly the power that the acoustic information that comprises in the source by sound converts that actual sound exports to, namely the sound that can hear of our people's ear; But " base power " is actual is do not export;
" final output power " is only the power that actual sound exports, and it adjusts " base power " for " base power " basis " UI Preferences volume ", thus obtains " final output power "; Mathematical relation possibility between different mobile terminals that " base power " basis " UI Preferences volume " obtains " final output power " is variant, but is fixing on a mobile terminal; " final output power " is exactly foregoing W1, and " UI Preferences volume " is exactly foregoing V1, therefore, can inverse operation obtain " base power "; The mathematical relation that such as " base power " basis " UI Preferences volume " obtains final output power obtains " final output power " (W1) for " base power " * " UI Preferences volume " (V1), then obtain " base power " for W1/V1 by inverse operation;
By above description, we can obtain according to (V1, the W1) in a moment " base power " in this moment, thus " final output power " corresponding under this moment all " UI Preferences volume " can be obtained;
In order to hereafter describe convenience, unification, make here to obtain inscribing when a series of (V1, W1) obtains these corresponding " base power " according to per interval T in step S301;

The final output power of the corresponding standard of UI Preferences volume 0 is 0
The final output power of the corresponding standard of UI Preferences volume 1 is 12
The final output power of the corresponding standard of UI Preferences volume 2 is 24
The final output power of the corresponding standard of UI Preferences volume 3 is 36
The final output power of the corresponding standard of UI Preferences volume 4 is 48
The final output power of the corresponding standard of UI Preferences volume 5 is 60
The final output power of the corresponding standard of UI Preferences volume 6 is 72
The final output power of the corresponding standard of UI Preferences volume 7 is 84
The final output power of the corresponding standard of UI Preferences volume 8 is 96
The final output power of the corresponding standard of UI Preferences volume 9 is 108
Carry out correspondence according to the mode of getting compared with proximity values, the volume control documents obtaining this music file is as follows:
UI Preferences volume 0 is 0 to the actual volume that arranges
UI Preferences volume 1 is 1 to the actual volume that arranges
UI Preferences volume 2 is 2 to the actual volume that arranges
