海外TECH	DEV Community	The Major Difference Between Web 2.0 and Web 3.0	https://dev.to/buchman/the-major-difference-between-web-20-and-web-30-pfc	The Major Difference Between Web and Web What is Web If you want to learn about the web vs web comparison in detail then you should start with Web It refers to the second generation of internet services which focused on enabling users to interact with content on the web Web fostered the growth of user generated content alongside interoperability and usability for end users The second generation web does not focus on modifying any technical specifications On the contrary it emphasizes changing the design of web pages and the ways of using them Web encouraged collaboration and interaction among users in PP transactions thereby setting the stage for e commerce and social media platforms  Apart from the favorable implications of interoperability interactivity and usability web also fosters interoperability across various services Another important highlight about Web in the Web and Web differences would refer to web browser technologies AJAX and JavaScript have emerged as formidable instruments for the creation of web websites  Features of Web It is also important to understand the distinctive features of web for a precise impression of web vs web Here are some of the notable traits you can identify with web  Web enables free information sorting thereby enabling users to collectively retrieve and classify the information  The second generation of internet services also focuses on ensuring dynamic content with high responsiveness to user inputs  Web also emphasizes evaluation and online commenting as channels for information flow between site users and site owners  Web enabled access to web content from televisions mobile devices multimedia consoles and almost any internet connected device  Most important of all web is also referred to as a participative social web Users could now participate in the creation and sharing of responsive content alongside presenting favorable prospects for collaboration Therefore one can clearly notice how web is vital in encouraging the growth of new virtual communities  With a distinct assortment of features you can move ahead with web vs web through an outline of the uses of web You could discover a wide range of online tools and portals which can allow people to share their experiences perspectives thoughts and opinions The web applications have showcased a formidable frontend revolution with more opportunities for interaction with the end users Users could find a wide range of applications in web for different applications Some of them include social media blogging web content voting social bookmarking podcasting and tagging  What is Web While web might look like an advanced approach to the internet it still harbors many setbacks What about the security of your personal data Trusted institutions take control over the data of users in Web especially due to the need for trusted intermediaries If two parties want to complete a transaction and they don t know or trust each other then they would have to rely on trusted intermediaries However the intermediary has control over the data storage and management thereby strengthening their grip over users In addition centralized power has never gone well in times of crisis thereby calling for decentralization The latter player in the question of “what is the difference between web and web has a promising solution to the setbacks in web Web presents a promising improvement over Web especially with major transformations in terms of infrastructure Also referred to as the semantic web the third generation of the web leverages an advanced metadata system The metadata system helps in structuring and arranging all types of data for making it readable for humans and machines The foremost advantage associated with Web is practically the best highlight in Web and Web differences Web takes away the need for centralized intermediaries and introduced the universality of information How Web is Revolutionary The understanding of web vs web comparison should also focus on the uniqueness of Web The third iteration of the web presents one formidable answer to setbacks of web with an emphasis on innovative technologies Web leverages artificial intelligence for powering machine to machine interaction alongside advanced analytics In addition Web also uses a decentralized network for passing data to the control of owners As a result users get the opportunity for exerting ownership of their data alongside determining the ways in which it should be shared Furthermore the web and web differences would also focus on improved privacy and security for users Web leverages encryption and distributed ledger technology for resolving the concerns of trust which were evident in Web  Noticeable Features of Web You can build a stronger foundation for understanding “What is the difference between Web and Web by focusing on the features of Web also Here are some of the crucial highlights about Web which would help in differentiating it from Web Web leverages artificial intelligence for offering correct results at a faster pace alongside accessing real time insights  Web also enables users to capitalize on the potential of D visuals and graphics  Another critical feature of Web refers to the Semantic Web functionality It implies that Web could support understanding the meaning of words As a result machines and humans could easily find share and analyze information in web You can also find the prominent trait of improved privacy and security in Web  The web and web differences would also focus on the safeguards for user data and identity Web employs advanced authorization mechanisms through distributed ledger technologies and encryption for securing user identity and data  I am a student in Zuri BlockgamesX Nestcoin and this is my first

海外TECH	Engadget	Arturia Efx Fragments makes granular approachable	https://www.engadget.com/arturia-efx-fragments-granular-vst-effect-193053457.html?src=rss	Arturia Efx Fragments makes granular approachableArturia has been on a bit of a roll over these last few years The company has always made top notch MIDI controllers and soft synths But in it announced the KeyStep Pro and PolyBrute ーdelivering the MIDI controller than many had been clamoring for and an analog polysynth that hasbowledpeopleover Maybe one day I ll be lucky enough to get my hands on one Then in it gave the MicroFreak and Pigments two hugefree updates upgraded its FX Collection with seven new plugins and launched the SQ V virtual synth which I fell instantly in love with Now the company is launching Efx Fragments a granular processor that that brings an experimental edge to its current effects lineup nbsp Granular is pretty trendy right now check out the Microcosm and Lemondrop for instance But it s also can be difficult to tame Arturia has been putting a lot of effort into making its software more user friendly though and that s clearly on display with Fragments Simply put it might be the most immediate and musical granular processor I ve ever used and gives the Microcosm a run for its money as a cheat code to creating beautiful ambient music But it is capable of much more than just epic drones The core of Efx Fragments is a granular engine with three distinctly different modes and a second buffer Depending on which mode you select the way it chops up and plays back incoming audio varies There s quot classic mode quot which is pretty much what everyone thinks of when they hear the phrase quot granular synthesis quot It s versatile and unique and very unapologetically digital Texture mode softens the harsh edges a bit and leans into granular s more ethereal side While Rhythmic mode goes in the opposite direction strengthening the stuttering and glitchy side nbsp That s not to say you can t make drones in Rhythmic mode or create driving rhythms in Texture mode you ll just have to work a little harder at it nbsp In addition to the core granular processing there s two effects slots for adding filtering reverb delay and other tone shapers a bit crushing section with five different modes a powerful panner and spatializer two assignable macros three function generators for modulation and a modulation sequencer Not to mention all the various tools available for manipulating the grains directly like size shape and pitch nbsp ArturaiIf that sounds like an overwhelming array of options don t worry there s a handy tutorial that helps you get familiar with the interface And the UI is impressively clean and intuitively laid out I wouldn t hesitate to recommend Fragments to someone that was new to granular effects Two things help keep it approachable beyond the excellent tutorial For one the more intimidating controls are stashed away in the advanced tab as is the case with many Arturia products And two the presets are excellent The presets cover everything from subtle background pads to chaotic jitters to dense other worldly drones and rhythmically complex pitch shifted delays There would be absolutely nothing wrong with simply sticking to the presets here But they re also useful as a jumping off point if you re still getting familiar with the world of granular processing or if you re like me and just lazy nbsp One super fun trick is to use Fragments as a time stretching effect When paired with the bit crusher it can make melodies feel like they re being run through digital molasses or drums sound like they re coming from another dimension nbsp My only complaint interface wise is that all of the modulation options are hidden in the advanced tab But at least there are randomization controls around each virtual knob that allows you to create some movement So while it s easy to get beautiful results with the aid of the presets to do even moderate sound design you ll have to venture into the advanced tab But you really should venture into the advanced tab If for no other reason than to see the super fun visualizer that brings me back to the days of Windows Engadget ·Arturia Efx Fragments samplesHonestly though the controls in the advanced mode aren t terribly hard to wrap your head around You can basically draw whatever shape you want in the function generators then click assign and hover over the parameter you want to control until you see blue numbers pop up next to it Then just click and drag up or down to set the modulation depth This is basically how all of Arturia s instruments work It s simple and effective way to make deep sound design tools feel more approachable One other thing to know is that granular processing can be pretty resource intensive I encountered stuttering and artifacts with the density turned up high even under ideal circumstances a simple audio loop and no other plugins running in Ableton Live with no other programs running on my MacBook Pro with a GHz i and GB RAM So be prepared to freeze or resample anything you re running through Fragments Efx Fragments is available now at an introductory price of though if you already own other Arturia products there s probably a steep discount waiting for you You can also get it bundled for free with FX Collection which is currently on sale for which isn t a bad deal at all nbsp	2022-03-01 19:30:53
