Once you do that and follow the steps provided here, bass compression is as easy as one, two, three. thus knee is how strict the detector is about the threshold level, with soft knee having early but lower ratios near the threshold and hard knee having specified ratio at the threshold level. Instead of engaging at a very specific point, the ratio creeps up from 1:1 (no compression) to the actually defined ratio over a set amount of dB. with a hard knee, you get the activity starting right at the threshold level. “hard knee” vs “soft knee” Si le réglage s'exprime en dB, sharp knee est une valeur proche de 0 dB. Then you can take advantage of your compressor’s attack setting and dial it back to a slower attack. Press question mark to learn the rest of the keyboard shortcuts, https://media.uaudio.com/blog/2009/april/doctors_6.jpg. To add to this, the attack time is the time it takes for the gain reduction to conform to the graph posted above. How to Get Light Tonal Compression. ._12xlue8dQ1odPw1J81FIGQ{display:inline-block;vertical-align:middle} The Knee on a compressor represents how fast the compression is applied to the signal once it surpasses the threshold. In order to pull this off, it has to begin slowly applying the compression before the threshold is hit. New comments cannot be posted and votes cannot be cast, More posts from the audioengineering community. Think of it more like a synthesiser envelope where longer attack times produce a slower build up to maximum volume, or compression in this case, and faster times have a much quicker build up. This can give your acoustic guitar a chance to poke through the mix and sound like it has a lot of life. This is confusing. That's hard to say in all cases. Makeup gain is only really necessary for upward expansion. Products, practices, and stories about the profession or hobby of recording, editing, and producing audio. Dynamic range compression (DRC) or simply compression is an audio signal processing operation that reduces the volume of loud sounds or amplifies quiet sounds, thus reducing or compressing an audio signal's dynamic range.Compression is commonly used in sound recording and reproduction, broadcasting, live sound reinforcement and in some instrument amplifiers. For example, say your threshold was at -10dB with a hard knee...at -11dB nothing happens. You might not notice it as much on slower attack times, but with faster times it can make the transition into the compression appear more softly, so it doesn't sound as audibly snappy. How long this attack phase depends on the compressor “attack time”. Attack & Release. The knee is the way in which the compressor reacts to the signal. /*# sourceMappingURL=https://www.redditstatic.com/desktop2x/chunkCSS/ReredditLink.f7b66a91705891e84a09.css.map*/so attack is the speed of response, which can be tailored to the material to lessen or allow leading transients vs. the following sustain of the sound. This means most of the acoustic’s initial strums will pass through without any compression, but the ringing will be compressed a bit still keeping the track in check. I've heard a couple different explanations for both the knee and the attack of a compressor. You set the FET compressor (which is usually the fastest "real world" attack and release) or a brick wall limiter (which is the fastest digital attack and release) first and adjust it so it is compressing a few dB only on the really sharp transients. Think of it as sort of dialing in the compression rather than just turning it on an off based on the threshold, attack time, and ratio. As I rotate it clockwise, it opens it up more and lets more of the picking attack come through before the compression kicks in. /*# sourceMappingURL=https://www.redditstatic.com/desktop2x/chunkCSS/TopicLinksContainer.361933014be843c79476.css.map*/._2ppRhKEnnVueVHY_G-Ursy{-ms-flex-align:center;align-items:center;display:-ms-flexbox;display:flex;margin:22px 0 0;min-height:200px;overflow:hidden;position:relative}._2KLA5wMaJBHg0K2z1q0ci_{margin:0 -7px -8px}._1zdLtEEpuWI_Pnujn1lMF2{bottom:0;position:absolute;right:52px}._3s18OZ_KPHs2Ei416c7Q1l{margin:0 0 22px;position:relative}.LJjFa8EhquYX8xsTnb9n-{filter:grayscale(40%);position:absolute;top:11px}._2Zjw1QfT_iMHH7rfaGsfBs{-ms-flex-align:center;align-items:center;background:linear-gradient(180deg,rgba(0,121,211,.24),rgba(0,121,211,.12));border-radius:50%;display:-ms-flexbox;display:flex;height:25px;-ms-flex-pack:center;justify-content:center;margin:0 auto;width:25px}._2gaJVJ6_j7vwKV945EABN9{background-color:var(--newCommunityTheme-button);border-radius:50%;height:15px;width:15px;z-index:1} ._2cHgYGbfV9EZMSThqLt2tx{margin-bottom:16px;border-radius:4px}._3Q7WCNdCi77r0_CKPoDSFY{width:75%;height:24px}._2wgLWvNKnhoJX3DUVT_3F-,._3Q7WCNdCi77r0_CKPoDSFY{background:var(--newCommunityTheme-field);background-size:200%;margin-bottom:16px;border-radius:4px}._2wgLWvNKnhoJX3DUVT_3F-{width:100%;height:46px} This is a time-based number, usually in ms. Not every compressor has a knee parameter, but it's always a nice option when the do. "Programme Dependent Compression" seems to be what your alluding to unless we are talking basic Hard Knee/Soft Knee DBX type compression. A soft knee setting will apply the compression gradually until the full ratio is … Because “softer” knee settings are less aggressive, they are used far more often in mastering situations. When a sound overshoots the volume threshold, the compressor does not instantly apply the full compression to the overshooting signal. You will see the “linear” transition from +9dB until it reaches the +6dB output level. It allows you to determine how curved the transition from uncompressed- to compressed sound will be. Sur certains compresseurs on … knee is modulating the ratio around the threshold so onset of gain reduction is less noticed. If #2 from each are correct, that means that the knee starts working BEFORE the signal gets to the threshold right? Easing Up on Attack Time. ._2YJDRz5rCYQfu8YdgB_neb{overflow:hidden;position:relative}._2YJDRz5rCYQfu8YdgB_neb:before{background-image:url(https://www.redditstatic.com/desktop2x/img/reddit_pattern.png);content:"";filter:var(--newCommunityTheme-invertFilter);height:100%;position:absolute;width:100%}._37WD6iicVS6vGN0RomNTwh{padding:0 12px 12px;position:relative} Like a gain reduction ramp that affects the initial threshold signal at a slightly lesser ratio then depending on the knee setting moves into the normal ratio? A knee that is 6 dB wide won’t fully compress the signal until it hits 3 or sometimes 6 dB above the threshold (knee shapes may be different from compressor to compressor). The knee, as others have put it is more of an "ease in" to the compression. I think on some units it can be as you stated. The Peak Crest knob can be viewed as a blend control for what the plugin is reacting to. Attack time (when used in the traditional sense, ie a time constant) is the time it takes for the compressor to engage 66%. If you think this is correct, what do you think the attack time is for? this would be a 'soft knee'. I also recommend using a soft knee compressor for this approach if possible (just turn up the knee parameter if your compressor has one). The threshold goes down to -60dB in 0.1dB increments, and the attack and release knobs can be set to lightning fast or invisibly slow. The slowest attack time on a FET compressor is still faster than a tube compressor. ), and compressor types, (FET, opto, etc.) .LalRrQILNjt65y-p-QlWH{fill:var(--newRedditTheme-actionIcon);height:18px;width:18px}.LalRrQILNjt65y-p-QlWH rect{stroke:var(--newRedditTheme-metaText)}._3J2-xIxxxP9ISzeLWCOUVc{height:18px}.FyLpt0kIWG1bTDWZ8HIL1{margin-top:4px}._2ntJEAiwKXBGvxrJiqxx_2,._1SqBC7PQ5dMOdF0MhPIkA8{height:24px;vertical-align:middle;width:24px}._1SqBC7PQ5dMOdF0MhPIkA8{-ms-flex-align:center;align-items:center;display:-ms-inline-flexbox;display:inline-flex;-ms-flex-direction:row;flex-direction:row;-ms-flex-pack:center;justify-content:center} The compressor System object™ performs dynamic range compression independently across each input channel. At -9.9dB (or -10...whatever) full ratio starts, for example. .s5ap8yh1b4ZfwxvHizW3f{color:var(--newCommunityTheme-metaText);padding-top:5px}.s5ap8yh1b4ZfwxvHizW3f._19JhaP1slDQqu2XgT3vVS0{color:#ea0027} The Threshold setting determines when the compressor actually begins compressing. A link to one of those manual, that describe the attack time as basically a delay that does nothing until the time has been reached, would be great if you have the time. Say your threshold is -18dB and your ratio is 4:1. The attack property's default value is 0.003 and it can be set between 0 and 1. attack is NOT linear and is logarithmic in nature and there is a difference between FET / OPTO / VCA in their behavior with respect to attack & release curves. So it works on a whole different parameter. This is a time-based number, usually in ms. A soft knee setting applies compression differently to a hard knee setting.
