Thanks for this videos! They are great

[@akashmurthy]

Glad you think so!

what about SNANs and QNANs 🙃 how can we use them in c++ ?

[@akashmurthy]

From what I've read: "qNaN is generated by regular built-in (software or hardware) arithmetic operations with weird values sNaN is never generated by built-in operations, it can only be explicitly added by programmers, e.g. with std::numeric_limits::signaling_NaN" Obviously we don't want to be generating signalling NaNs in audio programming, since they cause exceptions.

Hi Akash, thanks for the Videos. Would it be possible for you to share a roadmap to become an Audio programmer. I am currently working as a software tester and a music composer/song writer by hobby and am happy to take an extended break from my job to venture into Audio Programming.

Thanks man! A roadmap, as in a set of things to learn? It's quite difficult for me to pin down exactly what you need to be an audio programmer, let alone an employed audio programmer. But I can list a few things here. Contact me directly if you want to talk more. 1) Proficiency in C++ is quite important I think, since most audio application development happen in C++. Modern C++, a bit of Cmake, clean code and following best practices. For this, there are plenty of resource. Cherno, Kate Gregory and CppCon have really good content regarding the language. 2) A bit of DSP to start off with. This is where my circumstances might be different. I studied a master's course in Music Technology, where I fast tracked my knowledge of DSP. But, there are plenty of resources that are invaluable. Any of Will Pirkle's books would be a great start. Again, there is no need to know everything. Pick a topic and try to implement something. Some simple things you could implement to get your feet wet: a delay effect, a simple synth, a sample player. The idea is to just get more experience being comfortable with the audio domain. Each one of these exercises will pose a different set of challenges that you have to overcome. Either technical challenges related to the language, or related to DSP. I would only deep dive into a certain DSP topic if I find myself implementing it. 3) The final step would be to find and familiarise yourself with a framework/tool for fasttracking application development. For me, JUCE is undoubtedly the best as a C++ framework. Again, Juce is quite vast, and you'll only need to know more things when you encounter a blocker.

@@akashmurthy many thanks for such an elaborate response. would start working on these lines.In the meantime, I have sent you a connection request on Linkedin by the name of Sumit Bhatia. Please could you add me to your network. Many thanks in advance.

Dear Akash. Which software do you use to create those amazing animations? Are they done with manim?

[@akashmurthy]

Hey Kostas, I don't use Manim, no. I just use Adobe After Effects for most of the animations.

@@akashmurthy thank you Akash. So much work!!!
