Intelligent Sound

Introduction and types of sound effects used in movies:
In terms of films and TV shows, sound effects point toward a completely different class of sound components. There are many different kinds of sound effects used in films and TV shows. They are;

• Hard sound effects: They are common sounds which are seen on the screen, like   door slams, gunfire, and vehicles driving by.
• Background sound effects: They are sounds which don’t completely coordinate with the picture, but denote setting to the audiences, like the sound of a fluorescent light being switched on and interiors of cars. The noise of crowd speaking in the backdrop is considered a background sound effect, but only on the condition that the language is unrecognizable.
• Foley sound effects: They are sounds which completely coordinate on the screen, and demand the skill of a foley artist to record appropriately. The movement concerning hand props, like forks and knives and the rustling of cloth are commonly seen examples of foley units.
• Design sound effects: They are sounds which don’t generally occur naturally, or are completely impossible to record in natural surrounding. These kind of sounds are utilized to depict extravagant technology in any sci-fi film, or may be used in a musical manner to denote an emotionally heavy mood.

Uses of sound effects in movies:
The entire process may be divided into 2 halves: the recording of all the sound effects, and their processing. Most sound effects are custom recorded for each and every project. However, if the clock and money do not permit, the step for recording may be replaced by utilizing huge libraries of sound effects that are already recorded. Although sound effect libraries can contain each and every effect that a producer needs, for reasons concerning timing, custom recorded sound effects are opted for.

Foley is one more method for adding sound effects. Foley is a technique to create sound effects and not a kind of sound effect by itself, but, it is commonly used to create the real world sounds which are extremely descriptive of the event being shown onscreen, like footsteps. With the help of this technique, the action onscreen is recreated to try and replicate it as much as possible. If done properly it becomes very difficult for audience to point out, what kind of sounds are added and which of the sounds are originally recorded. In earlier days, foley artists would mix sounds in realtime. Nowadays, with effects held in a digital format, it is simple to create any needed sequence to be played in any required timeline.
