State the second audio-frequency information and derive from same section audio source；
In embodiments of the present invention, by being provided with at least two recording device in terminal, the i.e. first recording
Device and the second recording device, the audio-frequency information of the first gathered acquisition of recording device is the first audio-frequency information,
The audio-frequency information that second recording device collection obtains is the second audio-frequency information.Terminal, when recording, uses the
Same section audio source is recorded by one recording device and the second recording device simultaneously, then the first audio-frequency information
Same section audio source is derived from the second audio-frequency information.Such as, a song is recorded by terminal, record
Time processed, use the first recording device and the second recording device to record, then then to obtain two sections of sounds simultaneously
Frequently information, the content of two these two section audios information is all this song.
103, judge whether described first audio-frequency information exists distorted sound frequency range, the most then perform step 104；
If it is not, then perform step 105；
When source of sound decibel is excessive, very big to vibration amplitude produced by recording device, and exceeded recording
During the amplitude range that device can bear, then can cause obtained audio-frequency information distortion, the sound of this distortion
Frequently message segment is distorted sound frequency range, and distorted sound frequency range is difficult to recover, thus causes terminal to export this audio frequency
During information, the experience of " distorsion " can be produced.Such as, use terminal in the scene in bar, use end
End is recorded, and owing to the noise in bar is relatively big, general terminal cannot record out clear high-quality recording,
And the audio frequency exported also would generally produce distorsion, have a strong impact on Consumer's Experience.In embodiments of the present invention,
In order to overcome this defect, terminal then gathers first respectively by the first recording device and the second recording device
Whether audio-frequency information and the second audio-frequency information, exist distorted sound frequency range in terminal judges the first audio-frequency information,
If existing, this first audio-frequency information is optimized process so that improve the quality of output audio-frequency information.
104, described distorted sound frequency range is replaced with audio section corresponding in described second audio-frequency information；
If the first audio-frequency information exists distorted sound frequency range, then this distorted sound frequency range is replaced with the second audio frequency
Audio section corresponding in information, forms the first new audio-frequency information, and this distorted sound frequency range replaces with second
Audio section corresponding in audio-frequency information is not distorted sound frequency range.So, the first new audio frequency formed
The most there is not distorted sound frequency range in information.
105, described first audio-frequency information is stored as target audio information；
If the first audio-frequency information does not exist distorted sound frequency range, then it represents that the recording matter of this first audio-frequency information
Measure higher, then need not this first audio-frequency information is optimized process, so by this first audio-frequency information
As target audio information.
106, described first audio-frequency information after storage is replaced；

As output audio-frequency information, when the audio-frequency information needing playback terminal to be recorded, then by this new first
Audio-frequency information plays out as output audio-frequency information.
In the embodiment of the present invention, terminal uses the first recording device collection to obtain the first audio-frequency information, uses
Second recording device collection obtains the second audio-frequency information, described first audio-frequency information and described second audio frequency letter
Breath derives from same section audio source；Described in terminal judges, whether the first audio-frequency information exists distorted sound frequency range,
When described first audio-frequency information exists distorted sound frequency range, then described distorted sound frequency range is replaced with described
Audio section corresponding in two audio-frequency informations, described first audio-frequency information after terminal storage replacement.So,
Terminal carries out audio collection, and the two ends audio frequency that will obtain by two recording devices to same section audio source
Information is mixed, obtain new mix after audio-frequency information eliminate distorted sound frequency range, enabling
Outputting high quality audio-frequency information, improves the experience of user.

Second audio-frequency information；
In actual applications, optionally, before using the second recording device just to gather the second audio-frequency information,
Terminal can also first obtain triggering command, and this triggering command is used for indicating terminal to use the second recording device to adopt
Collection obtains the second audio-frequency information.
The acquisition pattern of concrete triggering command includes two kinds, and first kind of way is: it is defeated that terminal receives user
The instruction entered.Such as, terminal is smart mobile phone, when user uses this smart mobile phone to record, and this intelligence
Can point out two kinds of record types of user by mobile phone, one is to use the first recording device to record, and another kind is to make
Record with the first recording device and the second recording device simultaneously.User selects use first by gesture instruction
When recording device and the second recording device are recorded simultaneously, then can produce triggering command, terminal gets triggering
After instruction, then the second recording device collection is driven to obtain the second audio-frequency information.
The second way is: terminal automatically triggers the second recording device and is acquired obtaining the second audio-frequency information.
Specifically, terminal first uses the first recording device collection to obtain the first audio-frequency information, in Preset Time,
In the most first 2 seconds, this first audio-frequency information of the first gathered acquisition of recording device in 2 seconds of terminal judges
Whether there is distorted sound frequency range, if existing, then it represents that the first sound of this gathered acquisition of the first recording device
Frequently information quality is relatively low, it is possible to create distorsion, so terminal triggers use the second recording device simultaneously automatically
Gather and obtain the second audio-frequency information.Optionally, due in Preset Time the second recording device fail participate in
Gather and obtain the second source information, so the first new source information of mixed composition needs to retain
Audio section in the described Preset Time that first audio-frequency information is gathered, this audio section can be carried out by terminal
Optimize and go dry grade to process so that this audio section becomes apparent from.

It should be noted that Codec could be arranged to two or more, it is also possible to be set to one, Codec
Having multiplex function, Codec can connect the first recording device and second and record device.
Optionally, described first recording device is mike, and described second recording device is speaker, or
Person's the first recording device is speaker, and the second recording device is mike.Owing to mike is as special
Recording device, so the sensitivity of mike is higher such that it is able to record trickleer sound, but
Owing to sensitivity of microphone is too high, and the sound higher for decibel may be caused, easily produce distortion,
And cause the situation of " distorsion ".Speaker is called outside speaker, and speaker is mainly used in voice output,
But the composition device of speaker is similar to mike, and speaker has the function of recording, speaker
Sensitivity is relatively low, so speaker may be produced vibration for trickleer sound, thus cannot
It is acquired.But speaker is for the higher sound of decibel, and produced vibrations are then relative to mike
Less, then not easily lead to distortion.Therefore, if use mike and speaker to gather same section of sound simultaneously
Source, although the first audio-frequency information obtained and the second audio-frequency information content are identical, but amplitude is different.
