Description

A kind of sound recording method and device

Technical field

The present invention relates to audio recording technology, espespecially a kind of sound recording method and device.

Background technique

Stereo (stereo) uses two or more independent audio accesses, in the loudspeaking that a pair configures in a symmetrical Occur on device.People can hear it is stereo, be because source of sound relative to two ears have loudness poor (acoustic pressure with propagation distance be inversely proportional) and Phase difference (time that same sound source reaches two ears is different, and vibrational state is also different), along with head, shoulder and auricle reflection and Diffraction, human brain can judge direction and the distance of sound source according to these information.Listen stereosonic principle similar with human ear, by two A microphone (MIC) can record the same source of sound loudness difference and phase difference, here it is stereophony record principle.

Although the sound quality and sound field effect of stereophony are much better than monophonic, since it can only reproduce one The spatial impression of two-dimensional surface, therefore, it can not allow people to stay presence therein in terms of home theater.In order to give spectators When appreciating film, the comprehensive three-dimensional space sense of one whole sound field, multichannel technology have developed therewith.

Up to now, there are recording and the broadcast modes such as two-channel, 5.1 sound channels, 7.1 sound channels.Existing multitrack recording The recording of multiple monophonics in fact, finished product disc shown it is stereo be in fact audio mixer's post-processing result.Cause This, the personage that existing multitrack recording needs some comparisons professional could complete.

In addition, currently, popularizing with mobile terminal (such as mobile phone), people can use mobile phone.Although currently on the market Mobile phone all there is sound-recording function, but most of mobile phone only one microphone is only able to achieve monaural recording.It is double to realize The recording of sound channel or multichannel needs to configure at least two recording microphones on mobile phone, in this way, equipment cost can be then improved, And needing to change mobile phone hardware structure, versatility is poor.
