![]() You can avoid a unwanted sounds by doing your recording indoors with the windows closed and the air-conditioning off (a lot of footage in studio movies is shot on sound stages, which are specially constructed sound-proofed buildings). However, if you plan on NOT doing any editing afterward, you should record the audio the old-style way and try to get as much ‘signal’ as possible, getting as little noise as possible and all the while avoiding distortion. ![]() It is quite common to record at -12 to -18 db and increase the audio levels later. With digital recording, however, if you are going to edit it later, there is no need to push the envelope. In old analogue recording, it was important to record the audio at as high a level as possible (but without being so high as to get distortion). If you don’t have a visual display, then you just have to listen for the distortion. If you have a visual display of audio input levels on your camcorder, you should make sure the the level never hits zero, which in digital recording is the point at which the signal distorts or clips. To get a good signal to noise ratio, you may need to record in a controllable environment and move the camera closer to the source. ![]() It is hard to get rid of background noise once it is recorded. You should try to get more of the sound you want to hear (e.g., dialogue) and less of the sounds you don’t want to hear (e.g., camera hiss, wind sounds etc.). Work towards a high signal to noise ratio There several things to consider when recording audio: 1.
