Production Tecniques

Sequencing

In film and TV, the audio portion of a project is recorded separately from the video. Unlike your home video camera, the film or video cameras used in professional productions don't have built-in microphones. Instead, all dialogue is recorded with either a boom or a tiny, wireless lavalier mic that can be hidden in an actor's clothing. Most other audio, like ambient background noise and music is added in post-production

Sequencing is putting all part of a song together, in this case for sound designers working in post production sequencing will be putting all the sound effects, Foley effects and background noise and music together and time it with whats going on in the footage, By sequencing these sounds you move them around within the realm of the footage to arrange the sounds in a way you want them to come across.

Synthesis

Synthesizers are almost always used in Sci-Fi and horror films because they can produce otherworldly sounds. But for straightforward emotion, horns are used too. These are associated with pageantry, the military, and the hunt, so they are used to suggest heroism. Movies featuring death-defying heroes such as Star Wars and RoboCop use a lot of horns.

Sampling

A software sampler is a piece of software which allows a computer to emulate the functionality of a sampler.

In the same way that a sampler has much in common with a synthesizer, software samplers are in many ways similar to software synthesizers and there is great deal of overlap between the two, but whereas a software synthesizer generates sounds algorithmically from mathematically-described tones or short-term wave forms, a software sampler always reproduces samples, often much longer than a second, as the first step of its algorithm.

Equalizing

In film sound, the sound designer matches sound to the look of the film. A sad movie has mood lighting, and the sound will be designed to match it in emotional tone. Its dialogue is EQ'd less crisply, with a lower-frequency boost.

In a happy comedy, lower frequencies are rolled off, and it's EQ'd and mixed to be "brighter."

Film sound is "sweetened" by manipulating room tone, premixing audio levels, and carefully considering dialog, music, and effects for their proper audio EQ.

Film sound expects post-production sweetening, which makes film audio sound so different from audio for video. Video sound can be sweetened, but Indies use it pretty much as it is recorded.

EQ can also alter the frequencies of the human voice to make them sound like they are on the phone which would be good in a scene where a character is on the phone and you hear the voice of the person on the other end.

Mixing

The key to mixing audio is to make it sound exactly how you want it to sound and make the recording of the sound even better, you do this by adding stuff like a compressor to reduce the dynamic range so that nothing is too loud or too quiet but in a sound effect you might want something to start at a low volume and then increase, in this case you would not want a compressor but add in a fader or filter. It all depends on what kind of sound you are going for, another thing to use is noise gate if you want to eliminate any background noise in a sound below a certain threshold
