Position:Live recording also has particular demand to pickup mike, in normally the state falls, we like to use what heart form points to to move inside the space that close encircle or capacitance mike comes pickup. Same, also can use strong directivity mike to have pickup inside the space that close, can maintain an actor so the audio consistency in all sorts of environments, but use such method a lot of for example come from meeting collect the reflection sound of the wall of the building, the sound that transcribe comes out has certain interference, often sound more barpque instead. And below the restriction that the mike using a group that heart form points to is removing physical character, its sensitivity is not as tall as mike of heart form capacitance and strong directivity mike, so unless be inside very narrow environment, it is the direct sound wave that collect comes from phonic source body commonly, the effect is idealer.
In blame we did not reflex an object inside the space that close, eliminated to reflex acoustical interference consequently, accordingly we can employ two kinds of pickup capable person that ability eliminates- - mike of heart form capacitance and strong directivity mike. And rather than closes the space often is us what say normally " outdoor " , in " outdoor " sound of sound insulation of block of content of very rare reflex travels, consequently sound wave can be passed very far, we should experience this kind of distant sound must use relatively acute pickup device, right now for the capacitance mike of opposite heart form, strong directivity mike exceeded mike of heart form capacitance greatly in the sensitivity on main shaft, because this is OK better collect comes from the sound of far, make the n of the signal of the language exceeds environmental sound, stress a language thereby, make a language more clear and do not suffer environmental audio interference. Accordingly, to avert all interference, outdoors recording, strong directivity mike is the optimal choice of sound engineer.
The sound engineer of familiar mike character should know the character of heart form mike and strong directivity mike, if main shaft of phonic source deviate is apart from certainly,be, can cause sound signal n to be decreased suddenly, affect tonal quality badly. Because of this recording mike it is quite important to put the position. Generally speaking, mike should be pointed to in the actor's upper part should be in the actor's mouth, if be two people and the roll that mike lever should have between the word when mike has only, but avoid by all means has roll when talk, such meetings cause the change with actor tonal language, sound quite factitious. Such place a method to want to notice mike and mike lever do not enter a picture, lest make a fool of oneself. If the actor undertakes athletic for long, can use the microphone that get mix, namely what we say normally " small bee " , but the attention does not let in motion the body and outside content and mike are acuteness collision, and want those who notice mike to concealment, do not expose in the picture.
