I've been meaning to try out some of the Faust

https://faust.grame.fr/

Some tutorials that were on the sister site a while ago. I was hoping to try it out for WASM.

From their website...

"The core component of Faust is its compiler. It allows to "translate" any Faust digital signal processing (DSP) specification to a wide range of non-domain specific languages such as C++, C, JAVA, JavaScript, LLVM bit code, WebAssembly, etc. In this regard, Faust can be seen as an alternative to C++ but is much simpler and intuitive to learn."

Maybe someone else has some more to add?

 

I've been thinking about what would be the best starting point for your goals and you might want to check this out. Solid DSP theory from a trusted book. Implemented in nice VST(JUCE) plugins with simple but useful GUIs.

A little bit of both but most of my work involved general programming. When I was a student (University Level) that's when I did most of the audio stuff but that was because I was interested in it. When I finished studying I did think about getting into audio software development but there just weren't enough opportunities in the country I'm from. From time to time I still do some technical writing (you might have read some of my manuals!) and beta testing for some audio companies but not much actual coding - I'm too busy trying to get my mixes to sound better

BTW, I think someone previously mentioned Java (and Python). The problem with Java is that it has automatic garbage collection which tends to blow up audio stuff! The thing to remember is that audio is in some ways more demanding than video because if there is any sort of delay in rendering the audio you'll get clicks, pops or worse. With video, framerates can slow down and users won't mind too much.

Another thing I always remember too, is that when I first started learning C, the lecturer told us that the initial learning curve is very steep. That is, it's very difficult to do anything programming-wise until you have a general overview and that takes some time. In programming, the rite of passage is to begin with a "Hello World!" program which prints out "Hello World" to the terminal. After that things get more difficult. It's kind of like trying to have a conversation with someone in a foreign language after learning a few phrases - you might be able to say "Hello" but after that it becomes a lot harder!

And one more thing while I think of it...if you're interested in real-time audio and you want to have some sort of GUI then you need to look into multithreading. If you're using the VST SDK or JUCE then I think it will be taken care of automatically. Otherwise, this is a whole other branch of programming to contend with. From memory, Ross Bencina has written some excellent articles that outline the problems.

I see. I can guess that the audio software industry isn't the one where you can make the most money or get a good job easily!

You are not alone

 

I was able to compile this bad boy. Very nice stuff. But you'll need the Intel IPP libraries or the CPU usage will rise like x2-x3

 

@ITHertz

Hi, do you know a forum or a community specifically oriented to audio software development?, could be nice something as this forum but with first interest in audio development, coding and then music production. I found some interesting forums but are more about electronics than programming

 

Code:

DSP and Plug-in Development

Hi Beat16, many thanks, checking some of the post in KVR I found this https://yofiel.com/audio/synthcore.php its intended for Max for Live but the raw code is easy to port to any language, pretty cool lib and useful for what I am doing.

Real time C++ coding's a bitch. From the DSP math to an implementation there're a lot of tricks, traps and nuances.
I can only advice to rely as much as possible on existing libraries. Even plugins in modular daw/host/plugin.

 

Yeah, that's hard. And why I advice a modular software approach. Of course, that limits the options oftentimes. In fact Juce comes with this amazing example app called AudioPluginHost that allows you to develop faster.

But no matter what Juce or other library does one unavoidable and huge problem of C++ is the loooong compiling times.
That's why I also usually recommend scripting plugins like Blue Cat's Audio Plug'N Script.

No clue. I guess there's an updated version?

Edited: I think is this one:

Congratulations - things are going well, I already have a suggestion for a name for the reverb, etc.: audiosex.pro!

 

This forum, the 'Software' Forum.
Of all the different forums here at AS, why not ask the mods to create a Software Development Forum too?
We have forums here for every other topic (under Navigation/Search Forums), and have many threads in them all.
Why not do it?

 

Oops, wrong thread, sorry
