I'm currently working on a project in Processing(version 3.1.1) for school which doesn't allow the use of external libraries(the project, that is)
I've successfully used the minim library and the Sound library before I found out external libraries aren't allowed. I can't find any information about adding sound to processing without the use of either of those. If anyone can help me further, link me to information or inform me it's not possible to do without external libraries, it'd be greatly appreciated.
I hope the Processing 3 Sound library by Processing Foundation isn't considered an external library by your school.
Otherwise you'll have to use raw Java using the javax.sound package.
You can find a couple of handy answer here and here
Short answer: no, there isn't a way to play sound using vanilla Processing.
The whole point of the Minim library is to add this functionality to Processing.
Keep in mind that Processing is written using Java, so you can use Java code inside your Processing sketch. Depending on how you're defining "external library", you could use Java to play a sound file. Google "Java play sound file" for a ton of results.
However, that really seems like overkill. Just use Minim. If you can't use Minim, then don't worry about adding sound.

i made a gui recently where the goal was to view the results of some actions there , so mostly it was like a simulation game that has no connection with any hardware , i proposed this for my school that uses moodle and i want to know if there is a way to integrate it there , the gui i used has controlP5 library and videos and gif libraries as well, i would appreciate the help
from my researches so far i found that we can integrate processing code with html after some modifications , but didn't find anything for moodle yet
My understanding is that Processing in java mode, using controlP5, etc. will work on a client machine, not on a server (like moodle) (not easily at least).
Regarding embedding a processing sketch a web page:
java applet support is deprecated (can no longer embed a .jar applet)
processing.js is deprecated (and controlP5 wouldn't be compatible anyway)
you can however port your code to p5.js
I don't know enough moodle, but perhaps you can embed a JS snippet/iframe/etc on a moodle page.
Regarding controlP5, in p5.js, you can look at p5.dom.js functionalities such as createSlider(), createButton(), etc. or use libraries like p5.gui or p5.touchgui.
I have a unique filter that I want to use while playing Audio files on MacOS and am trying to start based on an AudioKit example whereby I just replace a current effect with new code with my filtering. However, I can't find an example that is close to what I want and the amount of effort required to do from scratch is a bit too much. Is anyone aware of such examples that I can use? I've looked through all of the examples on AudioKit they either just play audio files or have effects but assume microphone data. Thanks
In the Developer directory of AudioKit you'll find an example called "ExtendingAudioKit" which is probably going to be your best template for how to set up a project that uses AudioKit for the base, but allows you to develop custom DSP external to AudioKit.
So I'm looking to build an application that will be able to record the users screen and stream it at the same time. I would like the application to run on both Windows and OSX. I don't have a high level of programming experience in any language, just basic understanding in C, C++, JS, (funny how each class you take in college wants a different language). I'm also pretty well versed in HTML and CSS but that is kind of irrelevant for this topic.
I've been looking around and it looks like the best solution is going to be writing the core of the program in one language, and then developing the Interface side for each platform differently, using appropriate languages and bindings for the different platforms (Objective-C and Cocoa for OSX and so forth).
I'm open to all suggestions, this project doesn't have a deadline or anything, I'm really just intending it as a learning experience. I've never done anything with video capture and streaming before, so I'm looking for suggestions as to which road to go down language-wise for this project.
Thanks in advance :)
the simplest solution that comes to my mind is to use VLC.
this is obviously not a "language" but an application, but it supports screen-capture and streaming on all of your target platforms (and more).
if this is not an option (e.g. because you don't want a separate application), you could use VLC's C-api for acquiring screen capture and use whatever you like for streaming.
if you want to only rely on native functionality, i would use C/C++ for the application and write the OSX part in ObjC/ObjC++ and Cocoa.
I was just thinking. C# has Winforms/WPF, Java has Swing and other frameworks, C++ has QT and so on; is it possible to create an application without using a Framework?
Putting aside the practicality of it, I'm just curious. How would one create an application that Just Works(tm) without needing external frameworks?
Two options come to mind:
Classical Win32 applications written in C. I don't know if standard Windows SDK API also counts as an "external framework" in your book, but that's as low as it gets.
DirectX/OpenGL games written from scratch with your own homebrew framework (not external, right?) There you get to do all the drawing yourself - although again, you use a pretty big library of primitive drawing functions.
If you want even less "framework", you'll have to code your own OS and drivers. :P
C# needs .NET Framework, not WinForms (which is an optional library used by some application). The same with Java.
Unmanaged (native) applications usually use some runtime library - the library of common functions. You can write a native application without any library - the compiler lets you do this, but you will need to (re)write lots of common functions, eg. for string manipulation etc..
Firstly, what is a framework?
Really a framework is just a bunch of code that is provided to you. You could, at least in theory, write the same code yourself. In that case you wouldn't be using a framework.
Your application can only do what the operating system allows it to do. Your program cannot directly manipulate the graphics card for example. So you have to use the APIs of your operating system in order to do anything.
So you are going to be calling into other code. (unless you write your own operating system). You will also being using another framework or api to get stuff done.
Yes. How: in the way that the frameworks you mentioned are implemented.
From a Windows point of view, you would register your window with Windows, then listen to window messages and react as required. Everything would be up to you - from drawing the window to building controls.
I am trying to port my screensaver from windows to mac and one of its features was reacting on system sound output. On windows it was easy using Direct Sound, but I can't find any example of capturing sound output on mac. Is it possible even possible without writing something like kernel extension? Using flash it is also very easy — it even gives computeSpectrum method to get raw data or even fft transformed data.
All programs that I have already found use Soundflower or their own kernel extension. But I don't think that asking to install separate program or using kernel extension is a good way.
One thing you can do, considering that Soundflower is open source, is take a look at how they did it. You can't copy & paste GPL code, but you can surely study the techniques used and create your own solution (point you in the right direction).
You won't find Apple being very helpful here. Sound capturing, in this manner, can be used for all kinds of nefarious purposes. I'm not even sure if Core Audio lets you do this without hacks. In any case, you have a working implementation of what you're trying to accomplish. I'd take advantage of it.
I'm not on my Mac right now, but I'm pretty sure that Quartz Composer has a patch for just this thing. Depending on what language you're writing your screen saver in, it may be fairly easy for you to port your code into a QC patch. Well... it probably won't be easy, but it may be doable.
