How do you become a C++ Standards Committee member?

Why is C++ prevalent in audio?

Should you still use it for audio software?

Honestly, Timur Doumler is someone I have looked up to ever since I saw his “C++ in the audio industry” talk at CppCon 2015.

He has a rich development history with C++ and/or audio:

• developer at Native Instruments
• developer of the JUCE C++ framework (podcast sponsor ❤️)
• C++ linter developer and developer advocate at JetBrains (who make the CLion IDE)
• founder of Cradle, an audio plugin startup
• C++ Standards Committee member
• CppCast podcast host
• notorious Audio Developer Conference and CppCon speaker

I have probably missed a ton of stuff here, but that should already give you a flavor of what Timur is up to 😉

I especially enjoy his technical talks on synchronization with the (real-time) audio thread; For example, at the Audio Developer Conference 2025, he made me finally understand memory ordering in C++ (or so I believe 😅)

In the podcast interview, we discuss his story, tactics, and tips, which I hope will inspire you to follow his footsteps (as they sure did me).

It also turns out we are both fond of the same music band… Listen to the interview to find out which one 😁

All in all, this one of my favorite podcast episodes (audio & C++, what more do you need?), so don’t miss it!

Kurt James Werner, PhD, is a senior research scientist at Soundtoys and one of my favorite researchers in audio DSP (virtual analog modeling in particular).

While you may not have read his papers, it’s very likely that you used one of the plugins he worked on:

• Neoverb
• Vinyl
• RX
• Guitar Rig (Hammond vibrato/chorus)
• Ozone
• Neutron
• Trash

If you start peeking into the research of modeling analog audio effects in plugins, you stumble across his name right away.

I consider him not only brilliant, but also insanely productive. Definitely a role model for me!

In the research world, he’s mostly known for his work on Wave Digital Filters (WDFs). It’s a technique for creating a mathematical model of an analog circuit that once done is easy to implement (provided you use a WDF library).

WDFs are great for modeling analog audio effects to put them inside plugins.

But as a true researcher, Kurt is involved many other audio subfields that we discuss in the podcast!

Did I mention that he’s a graduate from Stanford’s CCRMA?

In this episode, you’ll learn about Kurt’s transition from academia to industry, his work on products at iZotope, Native Instruments, and Soundtoys, and the realities of being a research scientist in an audio plugin company.

You’ll also learn all about WDFs, which is a powerful tool to master.

Trust me, you don’t want to miss this one 😉

Victor Zappi is a creator, researcher, and educator at the intersection of music, technology, and interaction design. He is currently an Assistant Professor of Music Technology at Northeastern University. In his career, among others, he worked on the Bela hardware platform during his time at Queen Mary University of London’s prestigious Centre for Digital Music (C4DM).

In this episode, apart from Victor’s inspiring career, we focus on digital musical instruments:

• What is a “good” digital musical instrument like?
• Is it a fixed “box” that you should learn how to play?
• Or should it be “abused” by opening “the box,” and messing with its internals?
• Can an artist change the digital instrument to make it their own?

We conclude with a discussion of Victor’s LDSP C++ framework, which enables low-level audio device control on Android devices.

This episode is a must-listen for anyone interested in the future of musical interfaces, hackable hardware, and the technology that drives them!

Ilias Bergström is a software engineer, researcher, and musician from Sweden. For most of his professional career, spanning over 20 years, he has been working on, as he describes it, “time-based media software.”

In the audio programming world, this means digital audio workstations, video editors, and live audio-visual performance software.

He generously shared his experience in Audio Developer Conference talks, two of which discuss the much underrepresented topic of the software architecture of digital audio workstations.

Software architecture and software design are fascinating topics to me, so I naturally devoured both of these talks 😉

In this interview, we explore not only Ilias’s journey but also go into the details of what makes audio software design hard. He discusses how he connects the dots between different types of media software through his long-running personal project, TWO, which is best described as a Media Control Workstation. It enables the simultaneous interactive combination of digital media control signals (such as OSC and MIDI) from multiple sources.

Finally, we don’t shy away from discussing our favorite books on audio software development! Given that Ilias shares a ton of valuable tips and resources, you don’t want to miss this one!

From this episode, you will learn:

• How Ilias’s interest in media creation software led to a career in audio, across both research and industry.
• How he combines music and audio with interaction design, Human Computer Interaction, and even topics such as neuroscience and psychology, and how audio development can be seen as a form of creative coding.
• How different media creation software tools (like DAWs) share the same core characteristics and core architecture.
• Insights into his personal software project, TWO.
• What does a PhD give you? What can a university education offer?
• The importance of software architecture, testing, and documentation.

Geraint Luff is a seasoned audio DSP developer and the founder of Signalsmith Audio. Geraint’s presentations, such as “Let’s Write a Reverb” and “Four Ways to Write a Pitch Shifter,” are among the most popular talks at the Audio Developer Conference (ADC) thanks to Geraint’s clarity of explanation and easy-to-understand visuals (not to mention the accompanying open-source repos).

In the interview, Geraint shares his insights on his career path, freelancing in the audio industry, and digital signal processing (DSP). He discusses how he gained traction as a freelancer by joining a community, delivering audio-focused technical talks, and sharing open-source repos. We can also learn his approach to learning DSP, problem-solving, and the significance of visualization in explanations.

Julian’s career is incredible: from natural sciences through a master’s in physical modeling, a PhD in virtual analog modeling, an almost decade-long position at Native Instruments, all the way to TikTok and Stability AI, where he’s working now on generative music algorithms.

There are few people who have such a rich background in audio research and industry and even fewer who are willing to share the details of it publicly. That makes this episode all the more exciting!

Jatin Chowdhury is quite well known in the audio programming community for his numerous contributions:

• various open- and closed-source audio plugins,
• a few published research papers on Virtual Analog modeling,
• a few audio-related talks, especially at the Audio Developer Conference,
• insightful Medium articles on creating audio software in general,
