Hello! The day before yesterday I saw an article about delay. I thought whether to translate or not, well, I decided.

Many Ways to Use Digital Delay

There are two of the most important effects in a guitarist's circuit - distortion and delay. And if you're taking your sound straight from an amp, whether clean or buzzy muddy, digital delay is important.

The Deja vu delay from Seymour Duncan is an example of a delay pedal that has modulation control and so, in addition to the usual delay effects, effects such as flanger and chorus can be produced.

Many guitarists think that the delay (DDL - Digital Delay Line) is the effect that gives us the echo sound. This is all true, but only until you tell them all that the delay is capable of. A multifunctional digital delay, with precise controls, complex modulation circuitry and straightforward controls, can produce a range of sounds - from flanger and chorus, doubling ambience, slapback and discrete repetitions that can be synchronized with the tempo - depending on from the values ​​of the rhythm. D? J? Seymour Duncan's vu is an example of a delay that has advanced modulation controls, but other pedals including the Empress Superdelay or Diamond Memory Lane 2 do the same. Well, if you want to choose best analog and digital delay pedal, you can read our review! Here we describe all types of the analog and digital pedals, so, you need just to choose the best.

Some shrewd guitarists use more than one delay in their chain, giving each of them its own functions, even if these pedals have the same parameters. Digital delay is one effect that works especially well when coupled to itself. Let's take a look at what digital delay can serve as a guitar player.

Basic operations with digital delay

Most people know or have guesses about how delay works - it makes an exact copy (sample or, in fact, digital recording) of the original signal in real time, and then mixes the signals together. The usual controls for delay are Delay Time, i.e. time in ms, showing how much later the recorded signal will be played after the original; Effect Level, i.e. the volume of the repeated signal relative to the original, Feedback is about the same as saying "the number of repetitions", which can vary from one to infinity.

Almost all delays have two separate outputs, which allow separate switching of the processed and dry signals to different places. Of course, you can take a mixed signal from one output (the most common use case) and just plug into the input of an amplifier, as most guitarists do. But it is also possible to connect different outputs to different places and devices, for example, to different channels of a stereo amplifier, or to different inputs of a mixer, or even to different amplifiers, to get a true stereo signal.

By using long delay times, you can get an exaggeratedly "wet" sound, for example, to fill in a slow solo note in a ballad, or get the famous "cascading" sound like Van Halen in Cathedral, Nuno Bettencourt in Flight of the Wounded Bumble Bee And Albert Lee in Country Boy or his solo in Luxury Liner by Emmlou Harris. With very long delay times (from a few seconds), you can turn your delay into a live recorder by overlaying and looping the played passages on top of each other and jamming. Such devices as the DigiTech JamMan, Line 6 DL4, Boss Loop Station - this loop recorders ( Looper ) (cyclic recording devices), which are in fact several digital delay in a single package, which allows you to overlay and looped sound.

We've covered the various delay options, now let's see examples of control values ​​to help you get the various effects available in your delay.

Delay Time and Effects

The delay time is the main factor in determining what kind of effect you want to get, be it modulation type (flanger, chorus), or more atmospheric echo and reverv. Figure 1 shows a graph of various effects versus delay time in milliseconds and modulation. Most high end delays have a modulation function, which is a variation (or variations) of a Low Frequency Oscillator (LFO). The LFO will decrease or increase the delay time depending on the oscillation of this lowest frequency. Depending on the initial delay settings and the amount of feedback, modulation control will help you get a falnger or chorus sound, or just make the sound sibilant. Set the modulation knob to zero if you want the delayed signal to be exactly the same as the input signal.

Some gadgets do without modulation adjustment, in which case you can hardly get a deep flanger and chorus sound. But the subtle effect that comes close to real chorus is, at times, what it takes to give the sound a little "movement".

Feedback control, also called regeneration, determines how many times the processed signal will be fed back to the processor input. With feedback set to zero, only one repeat will be produced, which is good for cascades, harmonies and loops, but not very good for ambient sounds or more "swirling" sound textures.

If the feedback is set to maximum, then an infinite number of repetitions will be produced, an infinite feedback, if you like. About 5 or 6 repetitions are good for reverb and slapback (an effect that is quite popular in rocobilly vocals), if every next rep is quieter it will emulate a natural echo effect.

The Effect level indicates how loud the processed signal will be in relation to the dry signal. When the effect level knob is set to zero, you will not hear any effect (only a dry, unprocessed signal will pass). When the effect level is set to 100%, the processed signal will be equal in volume to the original. Therefore, if you take the following three steps: 1) set a large delay (200 ms or more); 2) Effect level by 100%; 3) feedback and modulation to zero; then you will hear two identical notes or chords with a delay. This is a key element in the “cascading” sound, which also works well for rhythmic repetitions in sync with the tempo of the song.

Settings

Figure 2 shows an example of a delay pedal setting for some delay-based effects. The exact settings will depend on the musical situation and your preference. In general, it's better to set the delay time first, then the level, and only then move on to the Fibback and Modulation settings.

Conclusion

The short delay time for the delay is a set and forget. You just tweak the settings based on how the delay sounds and not worrying about how it interacts with the rest of the music. In other words, the same settings are suitable for both fast and slow tempos, it doesn't matter if the 16th or whole notes. But when the delay time goes beyond the slapback, i.e. 200+ ms, you have to fit the delay at a certain tempo and your rhythm patterns. It sometimes takes some math, but this is where the real fun begins.

The share of bagless vacuum cleaners in the markets - both Russian and international - is growing. Vacuum cleaners with bags are being replaced everywhere by cyclonic ones - with plastic containers for collecting dust. However, many customers remain unhappy with their cyclones: they are noisy and container cleaning is not as “basic” and hygienic as expected. Maybe the bag is better? We understand the merits of cyclones and "anticyclones".

League of Legends is a Multiplayer Online Battle Arena game that is essentially Dota’s heir. In LoL, the strategy and the RPG are ideally combined, and the fantasy MOBA arenas are laid at the base. Therefore, lovers of these genres can safely buy lol account At the moment, there are about 60 million people registered in the game, who have the opportunity to constantly participate in team fighting games of various kinds.

Let's start the League of Legends review with stylistics. Glance is bright colors that are maintained in everything from the design of menus and characters to the landscape. Thanks to such a colorful design, unique characters were created that differ radically among themselves, so that even a beginner will not be able to confuse the capabilities of his ward with another.

Just like in Dot, the user can manage real superheroes with their own history, a formed personality and the reasons why they can take part in team PvP. Here you can meet a dead hero, and a pioneer researcher, and a hired killer, and a ninja, and a lich. According to the idea of ​​the developers, the biography should become a kind of plot, which is based on the struggle between city-states, whose inhabitants are heroes. It should be given to the authors who participated in the creation of the characters, because they have a great sense of humor.

Continuing the review of League of Legends, I want to dwell on the main differences between the game and Dota. The developers have introduced additional components of the role-playing system, thanks to which players can develop not only selected characters, but also their virtual alternative ego. After each winning fight, you can get experience points and influence.

Once a player gains a certain amount of experience, his virtual alter ego (Summoner) will assume that he leads his character on the battlefield and is engaged in his control, while the ego is pumped to a new level and gain access to new spells, skills and rune slots . Before rushing into the fray, the user can add Summoner Spells to those that are originally installed in the hero. It is worth noting that these spells do not have a manacost, but there is a significant drawback - a long cooldown. But with all this, with their help you can make an instant jump in space forward, cast a slowing and blinding spell, move to the Allied tower or to a friendly hero, accelerate sharply, and so on.

In the League of Legends review, the user can insert runes and essences that are purchased for gold into empty slots. Each time after such manipulations, the hero will increase the level of health, speed of movement, receive a bonus to a critical strike and so on.

If we talk about Masteries, then they can be attributed to the tree of skills, which, like runes, directly affects the selected character, accelerating the reloading of his magic spells, so that after a certain amount of time, receive money from the air. The main difference from the runes - Masteries are completely free and are issued to the player with the transition to the next level. 1 level (out of 30 possible) - 1 point, which you can dispose of at your discretion.

All this gave users the opportunity to use various combinations of runes, spells and skills to enhance the selected character according to a specific tactic.

In the continuation of the League of Legends review, it is worth noting the second main difference between the game and Dota. It can be seen from the very beginning of the game - you can choose only 9 out of 60 heroes. This is all because the developers decided to make money this way - since the game is free, then the heroes will be paid for, and if there are no opportunities, then every week the players There are 9 randomly generated characters to choose from, from which you will have to choose.

But if you have an irresistible desire to play a certain character, then you can go in two ways:

1) Invest real money in the game and buy local currency (Riot Points), and then go to the store and buy the hero you like;

2) Play a couple of dozen games to accumulate a sufficient number of Influence Points, for which you can buy a character.

In any case, sooner or later, the right hero will be at your disposal. Even if it turns out to be one of the most expensive, then it can be accumulated for a couple of days, and a cheap one will cost only a few winning battles. Custom skins for heroes can only be bought for local currency.

In the review of the game League of Legends, you need to talk about the fact that two competing teams can have the same hero. There are two bases on the map, and trails are laid from them along which small monsters go. There are towers on the roads that can shoot and deal damage, but they have a small amount of health, so they can be destroyed much faster than in Dota.

On the bases themselves are shops in which characters can acquire artifacts and read the game attributes. On the roads themselves, you can find bushes, and if the hero enters them, it will become invisible to the enemy team. So this feature can be used to effectively attack enemies at the most inopportune moment for them.

Also in the League of Legends review, it is worth mentioning that in the game the developers decided to remove the "denay" mechanism, with which users could kill allied creeps and prevent enemies from gaining experience and gold for them. In the event of death, the character will not lose money, but for the murder of the hero you can earn a decent amount, which is distributed between the killer and his accomplices.

To see the range and defeat of spells, the player just needs to find circles on the ground. Among the neutral creeps that live in the forest, many mini-bosses have appeared, for the killing of which a temporary blessing is given, giving great strength to the hero for a certain period.

In general, if summarized, then not only avid gamers, but also inexperienced ones can play in LoL, because you don’t have to also often pull the mouse and knock on the keyboard, as in Dota. But at the same time, you need to properly develop the character, work effectively with the team and constantly monitor the map.

It is necessary to say in the review of the game League of Legends that the innovations also touched on the skills of the characters. For example, in DotA, magicians could inflict damage with their spells at the beginning and middle of the gameplay. But by the end, they were already not so effective and ceded their positions to the heroes with auto-attacks, because they strengthened them with artifacts, and magicians could not do this.

Therefore, the developers thought for a long time and came up with an innovation for magicians - the power of abilities with which you can affect the damage done by spells. So do not be afraid to play for the magician now, because he will remain effective, both at the beginning and at the end of the game.

Concluding the review of the game League of Legends, we can say with confidence that this is not Dota. A completely different reality, striking in its beauty and captivating plot. Fans of the genre should definitely like it. So hurry up to plunge into the exciting fabulous reality of LoL!

Coronavirus made me think of a hand sanitizer. I explain why you do not need to do a sanitizer with your own hands and where to buy an effective one.

Before, i buy a hand sanitizer at the special stores, but every day they became less and less. Then the sanitizers disappeared and I began to look for Russian effective antiseptics.

Last week I was lucky, I bought napkins with 70% ethyl alcohol. They ended up on sale, so I’ll tell you what antiseptics work, whether it’s worth panicking and doing sanitizers with your own hands.

How to use sanitizers

FIRST TIME, WASH YOUR HANDS WITH SOAP . ″ The best way to clean your hands is to wash them with water and soap after the street, public places and toilets, ’said Fran Wallach, assistant professor of infectious diseases at Sinai University in New York.

WASH HANDS FOR AT LEAST 20 SECONDS . An interesting study was conducted at the University of Hospitality, Michigan, America. Scientists have found that only 5% of people wash their hands enough to kill germs, and about 10% do not wash their hands at all.

HAND SANITIZER helps cleanse hands of bacteria and viruses without the use of soap and water. Sanitizers can be in the form of a spray, gel or cleaning wipes. Wipes are the most versatile, they disinfect hands and remove mechanical dirt from the surface. Check the purell singles advanced hand sanitizer gel fragrance-free 9630-08-ec at the our website.

Which hand sanitizers are effective

CHOOSE A SANITIZER WITH ALCOHOL . Look for ethyl alcohol or isopropyl alcohol (at least 60%). Only alcohol has a pronounced property against viruses. To keep your hands dry less, choose formulations with moisturizers, glycerin and aloe vera gel.

HAND WIPES BETTER SPRAY . Alcohol kills most viruses, but the virus also requires mechanical action. Friction relieves the surface of the hands of particles of someone's saliva or sneeze mechanically.

IF YOU HAVE A SANITIZER SPRAY, SPRAY IT BETWEEN FINGERS. This advice is given by Fran Wallach when using an antiseptic - spray in sufficient quantity on the surface of the palms and between the fingers, air dry for at least 10 seconds.

What sanitizers should not be used

REFUSE Triclosan . Triclosan in hand sanitizers is prohibited in almost all countries except Russia. Triclosan destroys local skin immunity, contributes to the appearance of mutant viruses and antibiotic-resistant bacteria.  

DO NOT USE TECHNICAL ALCOHOLS . Technical methyl alcohol (methanol) can be dangerous. Even if you only rub his hands, he can be absorbed through the skin.

DO NOT DO THE SANITIZER BY YOUR HANDS . There are many recipes for how to make a sanitizer with your own hands, but I do not recommend this. Such sanitizers will not provide the necessary protection, and a high concentration of essential oils can be dangerous even for ordinary people. And for children and allergy sufferers - even more so.

Where to buy hand sanitizer

CHOOSE A PRODUCT CONTAINING AT LEAST 60% OF ALCOHOL . Ethyl and isopropyl alcohol work effectively, with a content of 60% alcohol for treating hands and 70% alcohol for treating surfaces. Only such a sanitizer will be effective.

INJECTION WIPES . Contain 70% pure ethyl alcohol and are great for handling hands, keyboards, mobile phones, headphones and mice. After such wipes, apply a thick moisturizer on your hands to reduce dry skin.

BUY ALCOHOLIC ACID SOLUTION . It is suitable for processing leather and surfaces in the house. It is better to carry out the treatment with medical gloves in order to reduce the effect of alcohol on the skin of the hands.

CALENDULA TUNING . Another effective and cheaper tool that you can buy in a pharmacy. Tincture contains 70% pure ethyl alcohol, so it works great as a sanitizer.

How to behave in public toilets

DO NOT USE SOAP . Bar soap in public toilets accumulates bacteria on the surface, so it is less common than liquid.

BEWARE WITH LIQUID SOAP . Do not be surprised, but liquid soap in dispensers also contains bacteria! Remember that dispensers are not disposable. Workers pour soap into them, but don’t clean the dispensers that thousands of people touch daily. Through the dispenser, bacteria enter the liquid soap.

PROCESS HANDS . After a public toilet, wash your hands with water, treat with a sanitizer and close the tap with a paper towel.

Today, stamps are used everywhere. Many companies have more than one print. The area of ​​demand for these attributes has long gone beyond the boundaries of business. Children's stamps are already being issued that contribute to the accelerated development of the child, prints for individuals, etc. But the main area of ​​use of such products remains entrepreneurial activity, government agencies. A stamp is often compared with a signature. They are similar in purpose. A signature is a unique stroke of a person’s hand. In fact, his calling card. The seals perform the same functions, but for the organization.

We often see such products. However, few can boast of knowledge of the technology of its manufacture. This information is useful for those who already have stamps or are going to purchase them. Having received this knowledge, you will understand what type of seals to choose for a particular case, what changes are permissible, how to check the compliance of the goods with state requirements. Today, on various Internet resources, for example, at https://mystampready.com/en/constructor/ you can use the designer to create a print so that it is easier for you to present your future print. We’ll talk about this in today's article.

Modern technologies

The manufacture of seals and stamps is a complex, multi-stage process. It requires professional skills, experience, equipment. Today, there are a number of methods by which to obtain the desired print. Each differs by several criteria and is optimal for specific cases. I highlight technologies:

• photopolymer;

• flash;

• curing;

• laser engraving on rubber.

Products differ in final cost. This must be considered when choosing the type of product. Typically, the price is proportional to the life of the stamp. But the quality is better checked individually. The warranty will be given only by specialists.

Photopolymer manufacturing

Traditional technology. The main advantage is the speed of manufacture and low cost of the final product. The cost of this type of product varies from several hundred rubles. The price depends on the following factors:

• the size;

• stock of paint;

• set of flowers.

Production time is 30-40 minutes. Such terms will be provided only by professionals. Some companies offer low cost but minimal guarantees. Therefore, it is better to look for the best value for money. A wide range of products and reasonable cost distinguishes the company from competitors.

Flash stamps

A modern approach to the production of these attributes guarantees quality. A feature of flash technology is the absence of a stamp pad. Paint is injected directly into the porous preform. The method has several advantages:

1. Environmental friendliness.

2. Lack of room requirements.

3. Large working stock.

4. Low cost price.

5. High quality print.

For the manufacture of flash seals requires special equipment, it is expensive. Due to this, many firms inflate the price of products. However, if you have sufficient finances, it is still worth buying such a seal.

Vulcanization and laser technology

Two advanced methods of manufacturing such products. The peculiarity of vulcanization is the ability to create large-format goods (up to A5) and the simultaneous production of several stamps. The cliches are durable, they are characterized by increased resistance to ink. Great for industrial use.

Laser technology allows for a unique print layout. Due to the beam, a pattern of any complexity is created on the working surface. With the help of modern equipment, these products are made with different colors.
