ĭynamic range should be taken into consideration when determining where the video or film will end up being viewed. These extreme peaks and valleys, or dynamics, are represented visually by the waveform. In audio, the dynamic range measures the difference between the loudest part of a piece of audio and the lowest. To understand compression, you first have to understand dynamic range. For video editors who handle voice-overs, production audio, or even rough mixing, knowing how to use a compressor will come in handy all the time. However, it definitely isn’t the easiest to learn. Besides EQ, compression might be the most ubiquitous term in the audio world.
