Digital modeling of analog guitar distortion effects

Circuit design *Manufacture and development of electronics *Software DIY Sound

The sound of rock music, in particular of hard rock and heavy metal, is largely based on a specially distorted guitar sound, for which electronic “distortion” devices, tube amplifiers in “overloaded” mode, computers with appropriate software and digital processors are used. increasingly using neural network algorithms.

The distorted sound of electric guitars began to gain popularity around the 1960s. Since that time, the sound of overloaded tube amplifiers, connected to powerful dedicated guitar speakers with large dedicated speakers, has been considered the benchmark in rock music. But tube amplifiers were relatively expensive and inconvenient to operate. Therefore, semiconductor distortion devices were developed.

At that time, the electrical circuitry of distortion devices was relatively simple and the signal output from their output only vaguely resembled the sound of an overloaded tube amplifier. Nevertheless, it was still somewhat similar to the “sound of a lamp” and this provided a powerful incentive for designers of analog semiconductor distortion circuits to continue their research, complicate circuits and propose new circuit solutions. The heyday of analog solid-state distortion was around 1995-2010. The most popular were electrical circuit diagrams like those shown in the figure below.

Features to expect from Apple's upcoming AR/VR headset

Development for AR and VR *
Recovery mode

Apple next year is planning to enter a new product category, launching its first mixed reality headset. Rumors indicate that the upcoming headset will support both AR and VR technology, and that it will have features that will outshine competing products.

With the iPhone, iPad, and Apple Watch, Apple's hardware and software led it to dominate those categories within a few short years after entering a new market, and it's likely the same thing will happen with augmented and virtual reality. We've rounded up 10 features rumored for the AR/VR headset that will set it apart from competitors.

Queries in PostgreSQL. Nested Loop

Postgres Professional corporate blog PostgreSQL *SQL *
Translation

So far we've discussed query execution stagesstatistics, and the two basic data access methods: Sequential scan and Index scan.

The next item on the list is join methods. This article will remind you what logical join types are out there, and then discuss one of three physical join methods, the Nested loop join. Additionally, we will check out the row memoization feature introduced in PostgreSQL 14.

How to Customize UI Artefacts for Selenide + Selenoid + Allure (with TestOPS)

Иннотех corporate blog IT systems testing *Web services testing *Mobile applications testing *
Translation

The common combination of JUnit5, Selenide and Allure has proven to be stable and reliable for autotesting. The remaining issue, however, lies in test length increase up until the rise of overall test numbers. The resulting video files turn out to be over an hour. Alexander Kochergin, Lead engineer at Innotech, has found a way to simplify the process.

Size does matter… (part 1)

Git *Shells *Development for Android *Build automation *DevOps *
Translation
Tutorial

No matter how we deceive ourselves - size matters! Of course, we will talk about the size of our android application, where we add a bunch of cool features, and we don’t even think about how this can negatively affect the app size. Therefore, we will learn how to detect app size regression on CI to automate this process. In this part, we will discuss how you can easily check the app size in development branch.

Methodology for calculating results of a task set: taking into account its level of difficulty

IT Infrastructure *Mathematics *Statistics in IT IT-companies

In the world of academic knowledge evaluation, objective calculation of large data presents a serious problem. Can a student studying in an Advanced Maths class and getting B-marks be evaluated equally with another student, getting B-marks in a General Maths class? Can we create a system that would take into account the level of difficulty those students face?

This article will describe a system of independent evaluation we have been using for school olympics in five subjects (Mathematics, English Language, Russian Language, Tatar Language, Social Science) for students grades 1 to 11. In each academic year we organise six qualification tournaments, with about 15,000 students from different regions of Russia. Then we select the top ten participants in each subject and each grade for their future participation in the final (seventh) tournament, where only the best of the best are chosen. It means that 550 participants compete in the final tournament, which is about 5.5% of all participants in the academic year. 

It is obvious that those multiple tournaments cannot be absolutely homogenous, and inevitably the levels of difficulty for each set of tasks vary. Therefore, it is critical for us to take into consideration those variations of difficulty and calculate the results in the most objective manner.

Quantum Computers Without Math and Philosophy

Quantum technologies

In this article, I will break down all the secrets of quantum computers piece by piece: what superposition (useless) and entanglement (interesting effect) are, whether they can replace classical computers (no) and whether they can crack RSA (no). At the same time, I will not mention the wave function and annoying Bob and Alice that you might have seen in other articles about quantum machines.

The first and most important thing to know is that quantum computers have nothing to do with conventional ones. Quantum computers are analog in nature, they have no binary operations. You have probably already heard about Qubits that they have a state of 0, 1 and 0-1 at the same time and with the help of this feature calculations are very fast: this is a delusion. A qubit is a magnet (usually an atom or an electron) suspended in space, and it can rotate on all three axes. In fact, the rotations of a magnet in space are the operations of a quantum computer. Why can it speed up calculations? It was very difficult to find the answer, but the most patient readers will find it at the end of the article.

MUST HAVE FEATURES IN YOUR CRM

ИНТЕРВОЛГА corporate blog CRM systems *Business Models *

One of the major challenges facing companies that transitioned online is how to deliver quality and personal customer service to their clients without face-to-face interaction. It’s true that technology can cause exponential growth to companies. However, business owners and leaders must also guard this important aspect of running a business. Fortunately, there are now a lot of CRM systems or customer relationship management systems available online.

What are the features and objectives of CRM tools? Its most basic definition is any technology in the form of a system or an app that aims to manage all your relationships and interactions with clients and potential customers. 

Today, over 87% of businesses use a cloud-based CRM. That’s because it enhances business relationships and operations by giving organizations a more streamlined way to interact with their leads and customers. A CRM system enables companies to engage their customers, simplify processes, and increase income generation.
