Attack and Release times are program dependent, meaning they respond to the input signal and program material. For one thing, they almost always offer attack and release controls. Get started on your creative journey with the best in creative education taught by world-class instructors. 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 Slower attack times suit mastering uses and buss compression. Together, they are the most crucial settings for achieving natural, musical sounding compression. Attack time: 300ms Release time : 900ms. Join Graham Cochrane for Lesson 6: Fatter Drums : Fast Attack Settings of Compression & Dynamics Master Class on CreativeLive. Really compression on the parallel track (fast attack, slow release, medium ratio) can add a certain impact to an otherwise fat snare. 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). 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. For this reason, slow-attack compression tends to work well on hip-hop vocals, where clear diction is crucial. You get a more even and tight drum sound. 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. Note: a great feature that many plugin compressors have is … Together, they are the most crucial settings for achieving natural, musical sounding compression. You'll typically want to stick with a faster release in general. Set the attack too fast and your transients will be crushed. 6. Finally, slow down the attack time until you hear the transient pass through. Set the release too fast and you risk an unnatural pumping effect. A fast attack time is typically between 20 and 800us (microseconds) and slower times are in between 10 to 100 milliseconds. That really depends. Typical attack and release times for mid frequencies ( 250Hz to 5000Hz) This is where the vocal and mid range frequencies are found. “Fast-acting” compressors usually have release times of 100 milliseconds or less, whereas “slow-acting” compressors may … Percussive instruments may need a very fast attack to prevent signal overload due to transients. The attack and release controls shape how the compressor reacts. On vocals a fast attack can tame the over-powered singer who doesn’t know how to work the mic. That's How to Use a Compressor on Vocals! Vocals usually sound best with a slow attack. Available with seamless streaming across your devices. 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. Adjust the attack … 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. If volume changes are slow, you can push this to a high value. Attack Time: How soon the compressor starts to compress the dynamics after the threshold is exceeded. In most cases, a slower attack time is a better choice. It’s an all-around great style of compression for when the need to handle a wide variety of material arises. Set the release too fast and you risk an unnatural pumping effect. Just let the tone of the plugin do the job. Sometimes you might want a fast attack e.g. B. 6. Example 2D: PuigChild 670: Really liked how it sounded on this. Understand Multiband Compression Again, there are no hard and fast rules or formulas that work in all situations. For a kick and snare you want instant attack and fast release (50-80ms or so). Attack and Release can be set to fast, medium or slow. This combination lets you more precisely set the amount of compression and how loud a note must be in order to initiate gain reduction. The point of sidechain compression is to move sound out of the way for the important element to come through the mix clearly. Attack and Release define whether the compressor reaches its full range of gain reduction right away or more gradually. How To Nail The Perfect Attack Time: Start with a moderate setting (~5 ms). 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 … Most parts of a drum kit utilize a fast attack time, like the kick and snare, and some kinds of singing, like rapping. Attack: How quickly the compression begins once the input signal is above the threshold. a guitarist that picks really hard. 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. Vocals are highly transient and requires fast attack and release times. 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. Example – Short Attack and Release Times / Fast Compression System. Ultra-fast attack times will suck the life out of a bass performance by destroying its punch and impact. Attack and release define whether the compressor reaches its full range of gain reduction right away or more gradually. Start with fast attack/fast release and set the threshold to detect the signal’s transients. 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. The meter switch selects either output or reduction. 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 Basic Compressor Settings The slowest attack time on a FET compressor is still faster than a tube compressor. For this reason, it’s fantastic at taming transient content. Output has no effect on compression with an 1176, it simply sets the already processed master output level of the plug-in. Problem 2: My kick doesn’t cut through because it’s interfering with the bassline. A fast attack makes the compressor clamp down immediately while a slower one will let a part of the volume peak come through. FET compression is often used when color is desired, fast attack times are required, or both. It really depends on what you’re using the compressor for. Key to Attack/Release-Times Mentioned Below. Voltage controller amplitude compression acts on PEAK signal input and offers a fast attack and release. Set the attack time too fast and the compressor will respond quickly to the fleeting initial drum transient, reducing the gain swiftly. If your attack is set to 5ms, the compressor is going to kick in quickly and affect the initial attack of the note. You also want instant attack when sidechaining tracks to the kick or other important elements that warrant a sidechain from. It can also make a vocalist sound like they’re spitting out the words. 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. Setting an attack time that’s too fast. This will make the bass sound flat and lifeless. The ratio was set low at 2:1, the attack fast and release slow. '¨'¨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. It’s a type of compression that has a super fast attack, and therefore works really well on aggressive performances. 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. 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. Release: How long the compressor holds onto the signal once the input signal drops below the threshold. 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. 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. First and foremost, decide if you even need compression and go from there. Solution: Use sidechain compression 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. Used linked mode and got about 2dB of gain reduction. This will ensure that the impact of the bass comes through clearly. A fast attack would be useful for a rapper or anything that has sudden peaks early in the signal. 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. Notice how the compression gradually increases and gradually releases when the signal level crosses the threshold. Fast = 25-50ms; Medium = 100-500ms; Slow = 1–2sec (all are plus or minus). Example 2C: API 2500: Again, used feed back compression type with the knee on soft, thrust at medium. A slow attack can help the listener "grab onto" a sound, but won't sound great on vocals. 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. As you can see, there are no attack and release values that are ideal for every track. In this type of frequencies, I would like to use a high safety factor such as 10. Set the attack too fast and your transients will be crushed. The release control can really affect the sound of the compressor. Slow down the release time so that the gain reduction lasts until just before the start of the next transient. Mixing With Mike Mixing Tip on Using Fast Attack Compression on Drums Michael White. 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.
