From zero to sound in no time: Making Musical Apps – Real-time audio synthesis on Android and iOS

Making Musical Apps – Real-time audio synthesis on Android and iOS” couldn’t be more timely: I have started to play with Pd (Pure Data) recently and was wondering whether I could transfer my knowledge of Pd to other environments, such as my Android-powered smartphone. Written by Peter Brinkmann, the creator of the fantastic libpd library, this is the definitive introduction. For me it served not only as a guide to Pd on Android but also as a basic tutorial for development in Android (the book also includes a very short primer for Pd for beginners). Before this book I had not created any Android app at all and with the help of the book I found myself compiling and running sample music and sound apps on my Android phone in a few hours. What else can one ask for? More Pd and libpd knowledge would definitely not hurt but it would probably book to at least 300 – 400 pages. Besides, there are excellent and freely available resources for designing sound systems using Pd, and the book provides pointers to them.

In other words, if you want to build Pd powered applications using libpd for iPhone, iPad or Android phones and tablets, and are in need of a very quick guide to get you up to speed, then look no further. But also keep in mind that Pd system is a very sophisticated sound processing environment which requires dedication to master all of its aspects and details. Nevertheless, once you interactively design your sound application on the desktop, this book includes the necessary material to port your application to other devices. And for the impatient hackers out there, it also includes detailed explanations of RjDj (iOS) and ScenePlayer (Android) systems (and PdDroidParty and HTML based pd-webkit-droid) which help you run your Pd patches on respective devices without writing a single line of Objective C or Java code.

In addition to the sample apps that come with libpd (freely available from its GitHub repository), you can also get the source code of the sample applications and Pd patches described in the book from (which can serve as a solid starting point for your future projects). And if you ever need some technical help after debugging your libpd based app, be assured that the forum at is very responsive.

Time to slow down and analyze how we decide: Thinking, Fast and Slow

Thinking, Fast and Slow

Thinking, Fast and Slow

Can you understand the modern world you live in without having any idea about the following terms and the concepts they convey: ‘inflation’, ‘unemployment’, ‘advertisement’, ‘capitalism’, ‘liberalism’, ‘democracy’, ‘civil rights’, ‘energy’? In order to think about some field, to understand some aspects of our daily lives, and to communicate about them to the others, we need the terms describing them. Just like the terms given in the first sentence of this paragraph, the terms that became a part of our daily communication, we need terms and concepts to understand how our mind works in the modern world and what kind of pitfalls we face while we’re trying make thousands of decisions and form ideas every day.

So it is time that we learn about ‘anchoring effects’, ‘narrow framing’, ‘excessive coherence’, ‘endowment effect’, ‘planning fallacy’, ‘the illusion of validity’, and many other aspects of decision making and thinking, so that we can understand the processes we encounter every day much better.
