Compression for VO

Hey Reader,

You've probably heard the term "compression" in a voice-over context. It's one of those audio tools that can feel a bit like a mystery, but once you understand its purpose, it can become an essential part of your editing workflow.

So, what is compression? In the simplest terms, a compressor is like an automatic volume knob. It reduces the difference between the loudest and quietest parts of your recording, creating a more consistent and polished sound. This makes your voice sit better in a mix and prevents those sudden peaks in volume from being too jarring for the listener.

Here's a quick breakdown of the main settings you'll see on a typical compressor and how you should use them for VO.

​

Quick Guide to Compressor Settings

​

• Threshold: This is the most important setting. It determines the level at which the compressor "kicks in." Any sound that goes above the threshold will be compressed.
  • FOR VO: Set this just above the average speaking level of your voice.
• Ratio: This controls how much the signal is compressed once it crosses the threshold. A ratio of 2:1 means that for every 2 decibels the signal goes over the threshold, it will only be allowed to rise by 1 decibel.
  • FOR VO: A lower ratio (2:1 or 3:1) is great for subtle, natural-sounding voice-over compression.
• Attack: This is how quickly the compressor starts working once the sound crosses the threshold.
  • FOR VO: You generally want a fast attack time so it can catch and control those sudden loud sounds right away.
• Release: This is how quickly the compressor stops working after the sound drops back below the threshold.
  • FOR VO: A slightly slower release time often sounds more natural and avoids a "pumping" effect.
• Makeup Gain: Because compression lowers the overall volume of your track, you need to use the makeup gain to bring the level back up. This is a critical step! When you're A/Bing (comparing the compressed and uncompressed signal), make sure the perceived volume is the same. This way, you'll be able to hear the actual effect of the compressor, not just the change in loudness.

Don't be afraid to experiment with these settings on your own voice track. Start with a low ratio and a threshold that just catches your loudest parts. Your goal is a smooth, even sound—not something that sounds squashed or unnatural. Understanding compression will give you more control over your audio and help you deliver a truly professional product every time.
