What are the best DRC settings for dialogue, music, and sound effects?

1 Dialogue DRC

Dialogue is the most important element of any audio production, as it conveys the story and the emotions of the characters. Therefore, it needs to be clear, intelligible, and consistent throughout the project. DRC can help to achieve this by smoothing out the variations in volume and tone of the voice actors, especially if they have different microphones, recording environments, or vocal styles. A good DRC setting for dialogue is to use a low ratio (around 2:1 or 3:1), a moderate threshold (around -20 dB or -18 dB), a fast attack (around 1 ms or 2 ms), and a slow release (around 100 ms or 200 ms). This will gently compress the dialogue without making it sound unnatural or distorted.

2 Music DRC

Music is another key element of audio production, as it sets the mood and the atmosphere of the scene. However, music can also vary greatly in dynamic range, depending on the genre, the instruments, and the arrangement. DRC can help to adjust the music level to match the dialogue and the sound effects, without losing the musical details or dynamics. A good DRC setting for music is to use a moderate ratio (around 4:1 or 5:1), a low threshold (around -30 dB or -28 dB), a medium attack (around 10 ms or 20 ms), and a medium release (around 50 ms or 100 ms). This will compress the music moderately without making it sound flat or dull.

3 Sound effects DRC

Sound effects are the final element of audio production, as they add realism and impact to the scene. However, sound effects can also have a wide dynamic range, depending on the source, the distance, and the context. DRC can help to control the sound effects level to avoid clipping, distortion, or masking of the dialogue and the music, while still preserving the clarity and the punch of the sounds. A good DRC setting for sound effects is to use a high ratio (around 8:1 or 10:1), a high threshold (around -10 dB or -8 dB), a fast attack (around 0.1 ms or 0.2 ms), and a fast release (around 10 ms or 20 ms). This will compress the sound effects heavily without making them sound unnatural or noisy.

4 Applying DRC

To apply DRC to your audio tracks, you will need an audio software that has a built-in compressor plugin or a third-party compressor plugin that you can install. Some common audio software that have compressor plugins are Audacity, Adobe Audition, Pro Tools, Logic Pro, and Reaper. To use the compressor plugin, you will need to insert it on each audio track that you want to compress, and adjust the parameters according to the type of audio and your preference. You can also use a limiter plugin after the compressor plugin to prevent any peaks from exceeding a certain level, usually around -0.1 dB or -0.2 dB.

5 Checking DRC

After applying DRC to your audio tracks, you will need to check the results and make sure that they sound good and balanced. You can do this by using your ears, by using a metering plugin, or by using a loudness meter. Using your ears is the most subjective and intuitive way to check the DRC, but it can also be influenced by your listening environment, your speakers or headphones, and your personal taste. Using a metering plugin is a more objective and visual way to check the DRC, but it can also be confusing or misleading if you don't understand what the meters are showing you. Using a loudness meter is a more standardized and reliable way to check the DRC, but it can also be limiting or restrictive if you don't follow the loudness standards or recommendations for your target platform or audience.
