Want To Become A Software Developer In The World Of Audio?

You want or need to learn the basics of digital audio signal processing. It can be for a variety of reasons:

  • maybe you are a sound engineer who would like to create their own plugins and use them in the studio,
  • maybe you are a programmer (desktop/mobile/web) with a keen interest in music and you are wondering what you need to learn to start writing software specific for audio,
  • maybe you are a musician or a composer who would like to transition into a software developer position or you would like to simply understand better what happens under the hood of sound synthesizers and audio plugins,
  • maybe you are a student who is struggling with their university DSP course, has a poor lecturer, or would like to prepare for the exam and pass with a good grade,
  • maybe you want to land your first audio programming job,
  • maybe you already write audio software but you feel that you lack the necessary basics.

In any of these cases, you found it very difficult and frustrating to learn DSP on your own...

Help Me Understand DSP Now

Let's Face It: Learning DSP On Your Own Is Difficult.

Having your DSP questions answered takes time and frustration. Above all, it’s not fun and music-related stuff should always be fun.

How much time in total you spend looking up DSP terms? How much money does it cost you?

For example, I value my hour at 200 euro. If I spend 3 hours a week looking for information, I waste 600 euro. That’s quite a lot, if you ask me.

Now, imagine that you could read an audio-related blog post or a research paper and implement the presented application right away.

Imagine that you could quickly detect why your audio software is not behaving properly.

Imagine that you could start working the audio industry as a programmer and earning as an audio developer.

Maybe you love computer games and would like to work in the area of game audio. That’s definitely achievable, in fact, one of my clients reported to me that the game industry is still hungry for game audio developers.

Maybe you have a hobby project and would like to easily incorporate sound into it.

Or maybe you have an idea for a great new sound synthesizer or an audio plugin, one that would perfectly fit your creative needs. Imagine you could start implementing it right away.

That is possible now, thanks to the "DSP Pro" online course.

Who Am I And Why Should You Trust Me?

My name is Jan Wilczek and I am an audio software developer and a consultant for audio plugins and Android audio apps in programming languages like C, C++,  Python, MATLABŽ, Java, and Kotlin.

Since 2019, I've been running a YouTube channel, a podcast, and a blog on audio programming: TheWolfSound.com. I have personally helped clients from all around the world transition from roles of musicians, sound engineers, software developers, and composers into the world of audio programming, and land their first audio programming jobs.

I spoke at conferences like Digital Audio FX 2022 in Vienna and Audio Developer Conference 2022 in London.

My formal training was done in Acoustic Engineering and Computer Science at the AGH University of Science and Technology in Cracow and in Advanced Signal Processing & Communications Engineering at the University of Erlangen-NĂźrnberg, Fraunhoffer IIS ("home of mp3") in Germany, and the Aalto University in Finland.

I cannot imagine how much work went into this...

I get asked all the time how to learn DSP... I have always been ready to recommend Jan and his YouTube channel but now I have a go-to resource for anyone!

Nic Bretz

 Senior C# developer from the USA

Before I met Jan, I had purchased 15 books on DSP and watched tons of YouTube tutorials. However, nothing compares to the possiblity of directly asking questions and having them answered right away.

The course is exactly what I needed when I was starting out my hobby interest in audio processing.

Sound engineer and DSP student from the UK

Did Christmas come early?!

I'm really enjoying the course! It's a good pace, easy enough to grasp and the quiz questions really add a level of interactivity which makes it so much more than a video series.

Great job and it's so exciting!
