Fundamentals of Sound in Post-Production

Now that we have our sound recorded what do we do with it? In this lesson we cover the four types of filters commonly used in audio engineering including: Equalizer, Dynamic Range Controls (compressors), Noise Reduction, and Time Delay effects.
Now admittedly when I first started playing around with audio tools as a kid I had no idea what half of these things did (just that the reverb filter made it sound really reverby). But with a foundation in science of how sound works, these filters suddenly make more sense.
When you open up your audio editor, you will find a lot more advanced versions of these four basic types of tools (for instance Adobe Audition uses FFT for a lot of really powerful noise removal tricks) but if you understand how EQ affects frequency, how compressors reduce dynamic range and how Time Delay effects can color your sound, you’ll have a good grasp to begin working the sound in your film.
