3. Utilisez des filtres audio
« Filters are all around us. Air filters, coffee filters, oil
filters, and don't forget audio filters. That's right, there is a way
to remove some of the undesirable elements in your audio too. Audio
filters come in three basic types - low pass, high pass and band pass
- each does just what its name implies. Low pass filters allow the
lower frequencies through and block higher frequencies at a point you
specify. This is handy for minimizing hiss and other high frequency
noises. High pass filters work in much the same way, only allowing
the higher frequencies through while blocking the lower ones. This
type of filter is handy for eliminating boomy sounds like wind and
background noise along with certain types of hum. Band pass filters
work in the middle of the audio spectrum, allowing only those
frequencies within a specific range to pass through. Each of these
filters is a useful addition to your audio toolbox ».
4. Égalisez
« A cousin to filters, equalization is much like the tone control on
your home or car stereo - boosting and cutting certain ranges of the
audio spectrum.(...) But don't let the terminology intimidate you;
equalizers are very useful in shaping the sound quality of your
production audio. Maybe your talent has a small, thin voice. A
properly tuned equalizer can beef up the low end and add some sparkle
to the upper frequencies ».
5. Ajustez
« Many video editing programs include a feature that allows you to
adjust audio volume continuously throughout a clip. Premiere calls
these rubber bands and they are very simple to use. Expand the audio
track to the full view and you will see a red line running though the
middle of the waveform. Clicking anywhere on the red line creates a
handle that you can move up or down to adjust the audio volume ».

9. Désynchronisez si besoin
« One of the worst things that can happen in a video is for the audio
to fall out of synchronization with the picture, right? So why on
earth would you ever unlink the two? Well, actually, there are many
times when this is beneficial. In Premiere, simply right-click on
your video track and choose the option to Unlink Audio/Video. Now,
you have the ability to trim the in and out points of your audio
independent of the video. This offers the potential for some powerful
overlapping segments. Or maybe the audio portion of a particular clip
or series of clips is disposable ».
