Description
Technical field
The present invention relates to the output volume adjusting technology, the method and system that the output volume to media file when relating in particular to a kind of playing media file automatically adjusts.
Background technology
The broadcast of media file is very general in various multimedia application occasions.Because the diversity in media file source, therefore, volume as the media file of source file all is inconsistent usually, and in very large range there is fluctuation, though thereby cause the user to set in advance suitable output volume at one of them media file, but the inappropriate situation of output volume may appear when changing the another one playback of media files into, the situation that output volume during such as playing media file is too small or excessive, if this just needs the user to run into the inappropriate situation of the output volume that sets in advance, all to carry out the adjusting of output volume again at different media files at every turn.Even sometimes the user has arrived maximum with the output volume adjusting of media file, but still can't obtain suitable output volume.Below the solution at output volume adjusting in the prior art is introduced.
Here, before introducing the existing solution of various output volume adjusting, the simple earlier correlation technique that adopts usually when down output volume being regulated of introducing.
One: only can relate to adjusting when regulating output volume merely to the hardware output volume; Also can also need in conjunction with adjusting except relating to adjusting to the hardware output volume to the software output volume.Wherein, at the adjusting of hardware output volume, so-called hardware output volume refers to: the output volume of the media play hardware that is adopted during playing media file.Media play hardware is audio output apparatus normally, such as the output volume of the sound card equipment of user's personal computer (PC) machine.Can control the size of media file output volume during adjusting by the output volume of regulating sound card equipment.Other audio output apparatus outside non-sound card also can provide the adjusting interface of output volume equally, and manual adjustment is carried out at the adjusting interface by this output equipment during adjusting, perhaps carries out regulating and controlling by program.At the adjusting of software output volume, so-called software output volume refers to: the output volume of the media play software that is adopted during playing media file.That is to say, before voice data being sent to the output of media play hardware, can regulate the output volume that is obtained when adopting media play software playing media file by volume to media play software.Be to realize during adjusting by the algoritic module in the media play software.
When the adjusting of the adjusting of hardware output volume and software output volume combines, final output volume when the adjusting of software output volume equally also can have influence on playback of media files, its reason is: at this moment, size for the final output volume of playback of media files, be by the adjusting of software output volume and the coefficient result of adjusting of hardware output volume, voice data is the governing loop of process software output volume earlier, and then, finally obtain the final output volume of media file through the governing loop of hardware output volume.
Two: at the Principles of Regulation of output volume, the size of output volume (also crying gain) is to be determined by voice data amplitude size (the perhaps amplitude of waveform), but the two is not linear relation, but the relation of logarithm.The Principles of Regulation of output volume multiply by a coefficient to voice data exactly, and the value by this coefficient decides amplifies output volume or dwindle output volume.This coefficient is also referred to as gain coefficient usually.
Existing solution one: possess the function of output volume adjusting, but only relate to adjusting to the hardware output volume.This scheme is: set in advance an acquiescence output volume, if it is improper to give tacit consent to output volume when playing media file, then the user can realize the function of output volume adjusting by regulating the output volume such as the PC sound card equipment.The shortcoming of this scheme is: owing to the adjusting that only relates to the hardware output volume, therefore, for output volume originally with regard to very little media file, if it is just powerless that the hardware volume is adjusted to the situation that maximum can not meet the demands, adjusting not thorough.And if when having the big a plurality of different media files of output volume excursion to play simultaneously, the user needs to carry out manual adjustment one time in the time of may be at playback of media files.In a word, that not only regulates is not thorough, and can't realize the automatic adjusting of output volume.
Existing solution two: with respect to existing solution one,, also increased adjusting, can make the adjustable range of output volume bigger to the software output volume except relating to adjusting to the hardware output volume.This scheme is: set in advance a default software output volume and an acquiescence hardware output volume respectively, according to the acquiescence output volume of these two settings, respectively software output volume and hardware output volume are regulated.When playing media file, if the setting of the acquiescence output volume of these two settings is unreasonable, then the user can further regulate by manual adjustment software volume and hardware volume.The shortcoming of this scheme is: though increased link to the software output volume adjusting with respect to existing solution one, but still can not realize the automatic adjusting of output volume, if improper user intervention and the manual adjustment of needing equally of acquiescence output volume that is provided with.
Existing solution three: this scheme mainly is the automatic gain control of using for reference in the video conferencing system, be: the output volume that constantly detects media file, if depart from the target output volume that sets in advance, then transfer greatly or turn down the output volume of this media file automatically.The shortcoming of this scheme is: though can realize the automatic adjusting of output volume, but this automatic adjusting can cause the output volume variation tendency of same media file and this media file output volume variation tendency originally inconsistent, mainly be because the different gain coefficient of constantly regulating is inconsistent, for same media file, such as bigger at 1 second～3 seconds these media files output volume originally, and exceeded the target output volume that sets in advance, then output volume can be turned down automatically; And smaller at 3 seconds～5 seconds these media files output volume originally, and do not reach the target output volume that sets in advance, then output volume can be transferred big automatically; The rest may be inferred, must cause output volume and this media file output volume variation tendency originally of entire media file reality after automatic adjusting inconsistent, the output volume part is big or part is little, cause distortion, it is big or suddenly little to use the householder to see acoustically to feel its output volume of same media file to neglect, thereby greatly reduces the user experience sense.
In sum, more than each existing solution all have separately shortcoming, press for a kind of solution at present to output volume adjusting, can take into account the automatic adjusting and the user experience sense of output volume, between the two, do a good balance, that is to say, can realize the automatic adjusting of output volume, can avoid the reduction of user experience sense again.
