Audio post production is the process of crafting sound tracks for videos. Filmmakers are always looking for opportunities to improve the quality of sound on their videos. Audio post-production was born out of a desire by filmmakers to enhance the sound of their visions. Post production is the collection, grouping and the amalgamation of various parts of an audiovisual project to ultimately produce a master.
Audio post production is difficulty, tedious and time-consuming. However, it is very crucial in getting perfect recording. The audio post production entail the following stages
Once your work is complete. You will have several recordings such as
• dialog recorded during an interview
• wild sounds without images
• ambient sounds such as room tones
With the help of a sound recorder you can keep this recordings as standalone in either WAV or AIF format. Each recording is taken at a separate time, different locations and stored separately. You need to arrange them in order. Every file to keep where it belongs
You then pair each recording with an image, unless if you have no need of them. Therefore, you need to see to it that your audio and video can seamlessly sync. Even if the two were taken separately. Syncing ensure that the movements of the lips are in line with the video and so on. Traditionally syncing is done by use of clapboard but in recent times the Time Code together with an electronic slate is the most popular method. It is good for low-budget productions but it can be error-prone. That is why, you need to use a software to sync the audio and the video. This process is also called confirming because you have to match the audio and the visual. You can use the auto conform software that effortlessly automatically matches the two.
Editing is tedious because most people have to go it over and over before getting the desired project. Editors are never sure when a project will be ‘locked’. That’s why most projects involve many people. For instance, a feature film may have both a lead editor and an assistant editor. It is better to work together than do it alone and have to redo it countless time. It might not seem ideal but nothing ever is, especially when working on a creative projective that requires circular workflows.
The sound editor collects and groups audio tracks, not in the way the editor did but in a way to get an easy audio workflow. The audio recording are divided in four major categories:
All of these sounds are then
• Selected- finding the best possible recording
• Cleaned- to remove all irritant noise, artifacts etc.
• sieved- adding effects to manipulate the sound
• layered to sync with the images
This where the sound editor makes judgement on which audio recording needs to be redone. Every sound is tried and tested at this stage to be ready for the final step.
