The author discusses the implementation of speech recognition while recording from a microphone, featuring a cool visual effect similar to the new Siri. This is accompanied by real-time frequency spectrum distribution. The article provides a detailed explanation of the sound theory behind this distribution, including references to sources.

It looks impressive 😎

The author's repository also contains other interesting shader implementations.

During the development of this or that functionality, we often encounter challenges, and that’s perfectly normal.

There’s an interesting section called the Flutter UI Challenge, where fascinating interfaces are brought to life.

In this article, the author implements an animated electron using CustomPaint.

And of course, everything can be optimized further by using the repaint parameter instead of setState 😁

To work productively, it's essential to have comfortable environment — and a pleasant font for reading code is an important part of it. Finding the right font that suits you can take quite a bit of time. Recently, I came across an interesting service that offers a large collection of fonts suitable for coding. You can preview how each font looks, check for any limitations, and find a link to download it.

📌 The service is available at the link.
