It will be appreciated by those skilled in the art that, the subject of implementation of the embodiment of the way of recording of the present invention can be the terminal that mobile phone, panel computer, computing machine, recording pen etc. have sound-recording function, also can be other any devices of realizing the way of recording of the present invention, in the following embodiments, the subject of implementation of the way of recording of the present invention is preferably mobile phone, but the subject of implementation of the way of recording of the present invention is not limited.
The invention provides a kind of way of recording.
With reference to Fig. 1, Fig. 1 is the schematic flow sheet of the way of recording the first embodiment of the present invention.
In the way of recording the first embodiment of the present invention, the method comprises:
Step S10, obtains the audio analog signals of presetting duration, and the described audio analog signals obtaining is sampled, and obtains a plurality of audio sample value; According to described audio sample value, described audio analog signals is converted to audio digital signals, and described audio digital signals is stored to the first memory location;
After handset starting recording, in recording, obtain the audio analog signals of one section of default duration, default duration can be that mobile phone arranges according to historical data at every turn, or user arranges as required by mobile phone.The mode of obtaining the audio analog signals of one section of default duration can be to set a plurality of start time points, when each start time, point arrived, start to obtain the audio analog signals of this section of default duration that this start time point is corresponding, and the audio analog signals of the default duration of the preceding paragraph is stored in order to follow-up processing, for first start time point, when starting to obtain the audio analog signals of this section of default duration, owing to not obtaining before this audio analog signals, therefore, do not need the audio analog signals of the default duration of the preceding paragraph to store; Or, at the duration obtaining, be greater than the audio analog signals that intercepts default duration in the audio analog signals of presetting duration; Or, by other any attainable modes, obtain the audio analog signals of one section of default duration.
Mobile phone is sampled to the audio analog signals of the default duration obtaining, and obtains a plurality of audio sample value, according to audio sample value, the audio analog signals of this section of default duration is converted to audio digital signals.Mobile phone is stored to the first memory location by the audio digital signals being converted to, wherein, the first memory location can be set in advance by mobile phone by mobile phone or user, for example, the first memory location can be internal storage or external storage, and external storage comprises: hard disk, portable hard drive, USB flash disk, floppy disk, CD etc.
Step S20, according to a plurality of described audio sample value, judges whether described audio digital signals meets pre-conditioned;
Step S30, meets when pre-conditioned at described audio digital signals, stores described audio digital signals to the recording file that is arranged in the second memory location.
Pre-conditioned can being set in advance by mobile phone by mobile phone or user, for example, the mean value of audio sample value is greater than a certain preset value; Or the quantity that is greater than a certain preset value in audio sample value is greater than certain predetermined number; Or, utilize energy parameter value that audio sample value calculates or audio frequency parameter value in default scope.Certainly, being pre-conditionedly not limited to this, can also be that any applicable condition is to meet user's individual demand.
When a plurality of audio sample value that obtain meet when pre-conditioned, mobile phone is stored audio digital signals corresponding to this audio sample value to the recording file that is arranged in the second memory location.Wherein, the second memory location can be set in advance by mobile phone by mobile phone or user equally, and in addition, the second memory location and the first memory location can be identical, also can be different.
When a plurality of audio sample value that obtain do not meet when pre-conditioned, mobile phone can abandon audio digital signals corresponding to this audio sample value; Or audio digital signals corresponding to this audio sample value compressed and be stored to the 3rd memory location, at default time point, unifying to delete.
The present embodiment obtains the audio analog signals of default duration, and the described audio analog signals obtaining is sampled, and obtains a plurality of audio sample value; According to described audio sample value, described audio analog signals is converted to audio digital signals, and described audio digital signals is stored to the first memory location; According to a plurality of described audio sample value, judge whether described audio digital signals meets pre-conditioned; At described audio digital signals, meet when pre-conditioned, store described audio digital signals to the recording file that is arranged in the second memory location.Compared to prior art, the present embodiment is in recording, by meeting pre-conditioned audio digital signals, be stored to recording file, therefore, in recording file, only comprise the valuable sound clip to user, convenient for users to use, in addition, user can set pre-conditioned according to demand, thereby can meet the recording demand of user individual.
In one embodiment of the present invention, described in obtain the audio analog signals of default duration, the described audio analog signals obtaining is sampled, obtain a plurality of audio sample value; According to described audio sample value, described audio analog signals is converted to audio digital signals, and before described audio digital signals being stored to the step of the first memory location, the described way of recording also comprises:
When described sound signal meets recording condition, start recording;
When described sound signal does not meet recording condition, stop recording.
Wherein, sound signal can be audio analog signals, can be also audio digital signals.
With reference to Fig. 2, Fig. 2 is the schematic flow sheet of the way of recording the second embodiment of the present invention.
In the way of recording the second embodiment of the present invention, the difference of the present embodiment and the first embodiment is, the present embodiment is on the basis of the first embodiment, described according to a plurality of described audio sample value, judges whether described audio digital signals meets pre-conditioned step and comprise:
