Do I need compression for live sound?
Live sound is largely correcting problems with subtractive EQ. Sure, it’s fun to roll off some of the top-end on your hall reverb, but don’t let that distract you from the things that actually need attention. Compression should be used sparingly. The lead vocals should be the center of your attention.
What is the ratio in compression?
The compression ratio determines how much gain reduction the compressor applies when the signal passes a threshold level. For example, a ratio of 4:1 means that for every 4 dB the signal rises above the threshold, the compressor will increase the output by 1 dB.
What are good compressor settings for vocals?
Here are my go-to compression settings for vocals:
- Ratio: 1.5:1.
- Attack Time: 15ms (but up to 30ms for more punch)
- Release Time: 40ms.
- Threshold: -24dB.
- Gain Reduction: 2-3dB.
- Knee: Soft.
- Makeup Gain: 2dB.
What is a normal compression ratio?
Compression ratios usually vary between 1.05–7 per stage; however, a ratio of 3.5–4.0 per stage is considered maximum for most process operations. Quite often, the temperature rise of the gas during the compression dictates a limit for the safe or reasonable pressure rise.
How do you adjust compression ratio?
Try starting with a moderate to medium ratio of between 2:1 and 5:1. Set your attack time to a medium-fast setting and your release time to a medium setting. Now, gradually raise the threshold until you’re getting somewhere around 5 dB of gain reduction. Then set your output gain to compensate for the 5 dB attenuation.
When do you need to use compression in audio?
What is compression? Audio compression is the process of reducing the dynamic range of a sound. This compression occurs when the volume level signal exceeds a specified level. In practical terms, when a singer decides to belt out the chorus, instead of jumping for the fader, the compressor does the work for you.
What should I use compression in live settings?
For live rock show, 4-7 piece bands, I’ve had good success with the following guidelines. As with anything else, remember that these are just guidelines – every room, every gig, every setup is different, and what works for one combination may not work for another. Drums – usually, I’ll compress the entire submix for the drums.
How does audio compression affect the dynamic range?
Audio compression reduces the dynamic range of an audio signal. Dynamic range is the difference between the loudest and quietest parts of a waveform. Compression reduces this range by attenuating the louder signals and boosting the quieter signals. As a result, the loudest and softest parts are closer in volume, creating a more balanced sound.
Is there a perfect setting for vocal compression?
And I don’t want to mislead you. There is no one-size-fits-all formula to vocal compression. There are no magic settings that work 100% of the time. With that being said, it is possible to quickly dial in the right vocal compression settings, if you know what to listen for.
