If your attack is set to 5ms, the compressor is going to kick in quickly and affect the initial attack of the note. The vast majority of studio compressors also have both ratio and threshold controls, rather than a single knob to govern the amount of compression, as is found on most pedals. First and foremost, decide if you even need compression and go from there. Slower attack times suit mastering uses and buss compression. Ultra-fast attack times will suck the life out of a bass performance by destroying its punch and impact. This is the case of the new BEYOND Variable Speed Compressor (VSC) system, where two compressors in each channel—a slow-acting compressor and a fast-acting compressor—work in parallel to determine the … For one thing, they almost always offer attack and release controls. If you then set the release time very fast, the gain reduction will also reset very rapidly — well before the drum sound has finished, such that the lower‑level tail of the drum hit won't be compressed as much. This combination lets you more precisely set the amount of compression and how loud a note must be in order to initiate gain reduction. B. 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. Attack time: 300ms Release time : 900ms. It’s a type of compression that has a super fast attack, and therefore works really well on aggressive performances. Get started on your creative journey with the best in creative education taught by world-class instructors. Notice how the compression gradually increases and gradually releases when the signal level crosses the threshold. For this reason, slow-attack compression tends to work well on hip-hop vocals, where clear diction is crucial. They note that “fast” and “slow” compression release times refer to the time it takes for the circuit to return to the nominal gain value. A fast attack would be useful for a rapper or anything that has sudden peaks early in the signal. Vocals usually sound best with a slow attack. This compression would sound alot more natural than using 0ms for attack release times, but whether it is appropriate will depend alot on the style of music and the instrument you are compressing. VCA compressors are exceptionally useful due to a wide range of attack/release times and great controllability which allows them to simulate the sounds of a slow, smooth optical compressor and a super fast, snappy FET compressor. A slow attack can help the listener "grab onto" a sound, but won't sound great on vocals. The slowest attack time on a FET compressor is still faster than a tube compressor. How To Nail The Perfect Attack Time: Start with a moderate setting (~5 ms). It can also make a vocalist sound like they’re spitting out the words. A fast attack time is typically between 20 and 800us (microseconds) and slower times are in between 10 to 100 milliseconds. Often used as a way to emulate a tube circuit, these FET circuits have a special type of bright punch and warmth that you can hear when they are working. Attack: How quickly the compression begins once the input signal is above the threshold. Short attack times will result in a fast response to sudden, loud sounds, but will make the changes in volume much more obvious to listeners. Available with seamless streaming across your devices. The attack and release controls shape how the compressor reacts. Vocals are highly transient and requires fast attack and release times. As you can see, there are no attack and release values that are ideal for every track. Sometimes you might want a fast attack e.g. Slow down the release time so that the gain reduction lasts until just before the start of the next transient. Set the attack too fast and your transients will be crushed. It’s an all-around great style of compression for when the need to handle a wide variety of material arises. Most parts of a drum kit utilize a fast attack time, like the kick and snare, and some kinds of singing, like rapping. Release: How long the compressor holds onto the signal once the input signal drops below the threshold. Together, they are the most crucial settings for achieving natural, musical sounding compression. Set the attack time too fast and the compressor will respond quickly to the fleeting initial drum transient, reducing the gain swiftly. Attack Time: How soon the compressor starts to compress the dynamics after the threshold is exceeded. For this reason, it’s fantastic at taming transient content. Together, they are the most crucial settings for achieving natural, musical sounding compression. '¨'¨This type of compressor hits instruments in a different way, and you'll need to play with the Input, Output, Attack and Release to find what best fits your song. a guitarist that picks really hard. Typical attack and release times for mid frequencies ( 250Hz to 5000Hz) This is where the vocal and mid range frequencies are found. Understand Multiband Compression You also want instant attack when sidechaining tracks to the kick or other important elements that warrant a sidechain from. Fast = 25-50ms; Medium = 100-500ms; Slow = 1–2sec (all are plus or minus). Attack and release define whether the compressor reaches its full range of gain reduction right away or more gradually. Let’s look at an example of what happens to a signal in a hearing aid with a fast acting compression system (Figures 6 & 7). Again, there are no hard and fast rules or formulas that work in all situations. But if we use a slow attack time, the transient (start) of the note will slip through and the sustain (the rest of the note) will be compressed. Problem 2: My kick doesn’t cut through because it’s interfering with the bassline. The meter switch selects either output or reduction. One approach is the use of both fast-acting and slow-acting compression in the same hearing aid, but let each dominate the overall processing depending on the listening situation. 6. A fast attack makes the compressor clamp down immediately while a slower one will let a part of the volume peak come through. Join Graham Cochrane for Lesson 6: Fatter Drums : Fast Attack Settings of Compression & Dynamics Master Class on CreativeLive. Used linked mode and got about 2dB of gain reduction. If volume changes are slow, you can push this to a high value. This will make the bass sound flat and lifeless. Watch a free lesson today. Attack and Release define whether the compressor reaches its full range of gain reduction right away or more gradually. Percussive instruments may need a very fast attack to prevent signal overload due to transients. Set the release too fast and you risk an unnatural pumping effect. For a kick and snare you want instant attack and fast release (50-80ms or so). Studies on the effect of hearing aid compression time constants and compression ratios indicate that while fast regulation times may increase objectively measured speech intelligibility scores, slow regulation times seem to have a positive effect on 770 AudiologyOnline Article Attack and Release times are program dependent, meaning they respond to the input signal and program material. 6. That's How to Use a Compressor on Vocals! Key to Attack/Release-Times Mentioned Below. Example 2C: API 2500: Again, used feed back compression type with the knee on soft, thrust at medium. Finally, slow down the attack time until you hear the transient pass through. On vocals a fast attack can tame the over-powered singer who doesn’t know how to work the mic. Setting an attack time that’s too fast. An attack that is too fast could be disastrous on drums and other attack based instruments unless you are using parallel compression which people like Jeff regularly use out live. You'll typically want to stick with a faster release in general. When you get them right, your compressor works almost invisibly, but when those settings are too fast or too slow for the music, compression becomes obvious and intrusive. Mixing With Mike Mixing Tip on Using Fast Attack Compression on Drums Michael White. Solution: Use sidechain compression The release control can really affect the sound of the compressor. Start with fast attack/fast release and set the threshold to detect the signal’s transients. Basic Compressor Settings Set the release too fast and you risk an unnatural pumping effect. To use it in a practical scenario, let’s say you’ve got a snare top recording where the drummer gets a little happy during transitions. Set the attack too fast and your transients will be crushed. The ratio was set low at 2:1, the attack fast and release slow. Fast Attack; Fast Release; Why it works: The compressor reduces the gain of the peaks and lets you bring the level of your whole drum track higher. This will ensure that the impact of the bass comes through clearly. Attack and Release can be set to fast, medium or slow. Compression, fast attack So after reading a couple tutorials on using compression, it seems like it wise to avoid faster attack times for most things. The point of sidechain compression is to move sound out of the way for the important element to come through the mix clearly. It really depends on what you’re using the compressor for. Really compression on the parallel track (fast attack, slow release, medium ratio) can add a certain impact to an otherwise fat snare. Output has no effect on compression with an 1176, it simply sets the already processed master output level of the plug-in. That really depends. In this type of frequencies, I would like to use a high safety factor such as 10. for example they say (As a rule, avoid short (low) attack and release times) in this tutorial, so you dont kill the sound of the instruments transient: Using compression to add punch, warmth and power to your mix In Figure 6, we have a static input/output curve of the hearing aid in black, and then we have the dynamic input/output curve of the system in red. You get a more even and tight drum sound. FET compression is often used when color is desired, fast attack times are required, or both. Adjust the attack … In most cases, a slower attack time is a better choice. “Fast-acting” compressors usually have release times of 100 milliseconds or less, whereas “slow-acting” compressors may … Just let the tone of the plugin do the job. Note: a great feature that many plugin compressors have is … Example 2D: PuigChild 670: Really liked how it sounded on this. Voltage controller amplitude compression acts on PEAK signal input and offers a fast attack and release. Example – Short Attack and Release Times / Fast Compression System.
