Can anybody help me? I use Netbeans 8.2.

terminate called after throwing an instance of 'std::runtime_error' what(): RtApiAlsa::probeDeviceOpen: pcm device (hw:0,3) won't open for input. Could not run the sketch (Target VM failed to initialize).

Removing this function allows the code to run.

music = new SoundFile(this,"herbert.wav");

I believe this is a compatibility issue with Linux. I'm using Processing 3.2.1, the latest sound library, and Ubuntu 16.04.

I hope someone knows hows to solve this.

Thank you.

The whole thing works cool, but:

-somehow other circles start to appear for some reason that I don't want.

-it would be nice to avoid the delay as like this some notes are missed, but without it nothing appears.

-can't export pdf because of unknown exception. (image works) (???)

here is the code and image

thanks for your help!

I'm trying to make an animation which creates spheres. The brightness( cooler colors for loq freq, brighter for high) and the number and size of the spheres increase with amplitude. Can anyone help me with how to go about doing that?

This is my code so far:

int c = 255; float op = random(0, 255);

void setup() { size(960, 500, P3D); background(0); frameRate(25); noStroke(); rectMode(CENTER); }

void draw() { fill(c, random(100));

float sz = random(200); float big = random(1, 200); float placex = random(10, 960); float placey = random(10, 500);

fill(random(255), random(255), random(255)); ellipse(random(width), random(height), sz, sz); noStroke(); lights(); translate(placex, placey); sphere(big);

if (frameCount % 200 == 0) { c = 255 - c; // 255 0 255 0 255 0 .. } saveFrame("frame-####.tif");

if (frameCount > 500) { // 20 seconds * 25 fps = 500 noLoop(); } }

Is there a way to sonify DSM (Digital Suface Model) data?

And, does anyone know which is the best way/site to find and download DSM data from all over the world?

This is so important.

Thank you all in advance.

I tried using the Sound library but gave me the error "This library may not me properly installed", blah, blah, 64bits, blah...

I had the same error with the video one, but moving the folder to C:\ (I mean, with only english ASCII characters, no ñ or á), it worked. Now I don't know what the heck is going on with the Sound one :/

A library used by this sketch is not installed properly.

Picked up JAVA_TOOL_OPTIONS: -javaagent:/usr/share/java/jayatanaag.jar UnsatisfiedLinkError: processing.sound.MethClaInterface.busConstructMono()I A library relies on native code that's not available. Or only works properly when the sketch is run as a 32-bit application.

I've used the library before without any problems. I tried removing and installing the library, but it doesn't work. Any ideas?

Posso usá-la fora do draw()?

  for(int i = 0; i < groove.bufferSize() - 1; i++)
  {     
          groove.play();
          line(i, 50  + groove.left.get(i)*50,  i+1, 50  + groove.left.get(i+1)*50);
          line(i,150 + groove.right.get(i)*50, i+1,150 + groove.right.get(i+1)*50);
  }

I am desperately trying to find out how to properly merge Shiffman's video pixelation sketch with some Minim to make rects react to mic input and glitch.

Any idea? Any Minim thing for mic input?

Thank you all in advance.

Beads is a rich audio library with lots of capabilities for synthesis, generative sequencing and analysis. It also has lots of gaps, missing features and improvements that can be made. It has been a pet project of mine for several years, with valuable contributions from a number of collaborators. Once in a while I like to spam the lists to see who is using Beads, and if they'd like to contribute any of the code that they have written to the Beads library. You may already have some code sitting on your machine that is screaming to be free! You may have a Beads-related project that you're dying to realise. Failing that, it would also be interesting just to hear about what you are using Beads for and what you like/dislike about it (though this is not a call for feature-requests, there are plenty of those below!).

Anything you send will be considered for inclusion in the Beads library, or for inclusion on the Beadsproject.net website. Have your name added to the list of contributors!

Here are some valuable contributions that could be made to the library:

• Demos and examples - show off your creative work with Beads. Contribute tutorials and examples that help people learn and share best practice.

• Extra layers - If you work regularly with Beads, what code do you reuse the most? Can it make a reusable library that would reduce development overheads for others, or simplify using Beads in any way.

• Beads libraries - effects UGens, data classes, wave types. New sequencing tools. Better granular and additive synthesis tools, wavelets, phase vocoders. Build a set of higher-level tools such as FM synths.

More advanced projects:

• Beads analysis - produce high-level convenience classes for common analysis tasks, develop methods similar to Ableton Live for producing static analysis of audio files, that can be used for beat-synch, dynamic time warping, etc.

• Implement loop crossfade in SamplePlayer - long promised missing feature.

• Beads build - there are some things that would make the Beads source-code project easier to manage. Improved build scripts, merge all jar dependencies into the output jar, creating a Maven repository.

• Beads platform-specific distributions - create versions of Beads for Android, MaxMSP, VST, and perhaps even GWT/WebAudio (this should technically be possible as GWT allows cross compilation from Java to JavaScript. Audio support unknown). Create better tools (e.g., GUIs, config files) for adaptive configuration of Beads AudioContext and AudioIO on different platforms. Better integration with IO contexts such as Jack, coreaudio, Windows and Linux environments, and other drivers (e.g., via PortAudio, RTAudio).

• Beads core - new convenience classes for repetitive tasks, switch entire library to double precision, make use of Java 8 lambda expressions, profile and optimise the audio scheduler, better manage the GC, improved Sample loading, Sample streaming, comprehensive integration of OSC to control audio graph structures, audio network and network synch libraries.

• Beads tooling - make use of annotations, make an Eclipse or IntelliJ plugin for improved creative coding with Beads, or even maybe a standalone development environment, show Beads in action with Clojure, Groovy, etc. Make dedicated Beads project build tools. (Also I have some other code around that has Beads running on the Pi and listening for network messages).

Cheers!

I'd like to import and use the sound library with 64 bit 2.2.1, but can't find any instructions here, or on github pages. Which folders do I need to download? Do I need to create a folder to put them in? It's completely inscrutable to me at the moment.

I'm trying to make a three band equalizer in processing. Not only a graphic equalizer but one that you can actually use to limit the volume of certain frequency bands in the audio file that plays.

Has this ever been done? I could not find anything until now..

I have already made the visualization part using the FFT of the Minim library. It would be nice if I could somehow use the Minim library to control the equalizer as well.

I hope you have some ideas on how to approach this. Thanks in advance!

Just wanted to share my first Processing creation : WaveWatch, a soundcard oscilloscope 100% made with Processing.

Demonstration video (updated) : https://vimeo.com/banson/wavewatchdemo

It’s got all the features you’d expect from a standard scope,

• dual channel,
• configurable Triggering (single/Auto),
• time and voltage measurement,
• frequency calculation,
• markers with delta calculation

All you need is your computer soundcard, and Processing.

Project detailed documentation : http://www.banson.fr/wiki/doku.php?id=wavewatch

Download (GiHub repo) : https://github.com/bansonfr/WaveWatch

Project Background:

As a DIY audio maker, I was a fellow user of C.Zeitnitz’s Soundscope and the Zelscope software. Those are very good at their job and offer rich features, but suffer from several drawbacks, like a rough non-responsive GUI and Windows-only tools (Not to mention that they're paid proprietary tools).

WaveWatch development started one year ago with the goal to have a cross platform scope with basic measurement features running on both my workbench Linux PC and my home office personal computer. What began as a “filling-the-holes-rush-project” to empower my workbench PC ended up in a full featured oscilloscope that I use on a daily basis on all my audio projects.

I had in mind to focus on simplicity and efficiency, with mouse responsive GUI combined with handy keyboard shortcuts : when you need to perform an action, like moving a channel or calculating stuff, you’re always one click / keyboard stroke away from your result. It’s been proven to be very handy, I love it, and hope you will too.

I just posted a question along similar lines, here http://forum.processing.org/two/discussion/10796/sound-library-confusion#latest and thought my question was solved, now I am realizing it may not be as simple as I had hoped, as it looks like, as I understand it, that the Sound library can only monitor input audio, not output?

I have been messing with the Minim library and haven't figured out a way to transfer the audio output into number information. println("out"), out); returns ddf.minim.AudioOutput@73c66667

anyone know of a simple way to do this, or have a direction you might nudge me in?

Thanks!

I am trying to get some audio information from a video that I have playing using the video library in processing. I have been clicking around for a couple hours and have seemingly found a way that I can analyze the video's sound information and use the information to trigger events...

My answer came in the form of the sound library; https://processing.org/reference/libraries/sound/index.html

However I have not been able to get the library installed. The 'Sound' library doesn't show up in the 'sketch, import library' dropdown, nor does it appear in the list that you can search through by clicking 'add library'. The other 5 big ones do show up (PDF, DXF, Serial, Net, Video) and then it would appear that the sound library has been replaced by 'Minim'

When I search for documentation about 'minim' I haven't found anything very helpful, spare for that it is indeed a sound library of sorts.

I tried downloading the 'sound' library following the hyperlink off of the processing page I aforementioned, https://github.com/processing/processing-sound

but I don't know what the hell is going on with all of those files. haha.

Someday I will know the answer to all of this but for now I am a lost little n00bie, anyone out there have that magic insight I am looking for?

Thanks a ton!!

I am making use of the soundcipher library. I am not to much into music but I would like to create one Midi note with a specific beat.

For example: a Midi note of pitch 80 at beat 5 and a duration of 2BPS.

Can anyone help me how this can be done? Do I have to use the playNote method?

Thanks!

void KeyPress()
{
  keysPressed=0; //FOR EACH KEYPRESSED, ADD ONE TO TO AMP
  for (int i = 0; i < keys.length; i++) osc[i].adsr.unpatch(out); //Reset patches when keyPressed

  for (int i = 0; i < keys.length; i++)
  {

    if (key == keys[i]) //if keypressed is equal to an element from my array keys
    {
      keyState[i] = true; //set corresponding boolean from keyState array to true
    }
    if (keyState[i]) //for each active keyState add one to keypressed
    {

      keysPressed++;
    }
  }

  if (keysPressed == 0) amp = MAXAMP; //no keyspressed amplitude is equal to maxamp
  else amp=MAXAMP/keysPressed; //divide amplitude by amount of keyspressed, otherwise sound distorts

  for (int i = 0; i < keys.length; i++) osc[i].oscil.setAmplitude(amp); //set amplitude of each class individually to current amp

  for (int i=0;i<keys.length;i++)
  {
    if (keyState[i] && key == keys[i]) //if keyState[i] is true and corresponding key is active
    {
      osc[i].adsr.unpatch(out); //unpatch
      freq = Frequency.ofPitch(notes[i]+oct); //set freq to frequency
      osc[i].oscil.setFrequency(freq); //set freq
      osc[i].noteOn(); //initialise noteOn
    }
    else if (keyState[i]) { //if only keyState[i] is true, reset patch and turn noteOn, this ensures polyphony for keypressed
      osc[i].adsr.unpatch(out);
      osc[i].noteOn();
    }
  }  
}

Thanks for any assistance!

After I saw this TED-Ed talk () I was very impressed, so I decided to develop a simple rhythm engine that would work in a similar way.

You can find a short video of the software working here:

And you'll find the whole source code (3 files) here: https://github.com/ndrplz/RoundRhythm

Hope you'll enjoy! Best Regards,

I am trying to explore Examples starting on page 593 of the Processing Book by Casey Reas and Ben Fry. These examples depend on importing the krister.Ess library, but this library does not appear to be part of the libraries that come standard with Processing.

All my searches for the library have been blind allies so far. My question is whether this library is still in active development, and if so, from where can I download it?

My thanks in advance.

I am learning to use the minim library.

if(sound != null) {sound= sound + minim.loadFile("1.mp3") ;} 
else {sound= minim.loadFile("1.mp3") ;} 
sound.play();

I want to load and paste multiple audio files before playing the sound.

the + does not work, how can I do this?

Greetings and thanks.

I have a Processing2 application that works fine on my PC. When I tried it on a spare machine I got multiple Minim errors. This appears to be because the spare machine (Windows7) has no Speakers or Headphones plugged-in i.e. no playback device. When I plug in headphones all of the errors disappear and the code runs as normal.

Does anyone know of a simple way to detect the lack of playback device from within the code? I could then use this to skip the sound-related commands for any machine that has no sound.

Many thanks,

Batroost

Right now I'm simply trying to print the data coming in from audio input in this applet I'm modifying so that I can see the range of numbers coming in. I inserted "println(in)" at the end of the "void draw()" section to print the AudioInput variable, but it just prints this over and over: ddf.minim.AudioInput@416fa1ee

I'm stuck, any suggestions?

Here's the full code I'm working with:

import ddf.minim.*;

Minim minim; AudioInput in; color white;

void setup() { size(512, 200, P2D); white = color(255); colorMode(HSB,100); minim = new Minim(this); minim.debugOn();

// get a line in from Minim, default bit depth is 16 in = minim.getLineIn(Minim.STEREO, 512); background(0); }

void draw() { background(0); // draw the waveforms for(int i = 0; i < in.bufferSize() - 1; i++) { stroke((1+in.left.get(i))50,100,100); line(i, 50 + in.left.get(i)50, i+1, 50 + in.left.get(i+1)50); stroke(white); line(i, 150 + in.right.get(i)50, i+1, 150 + in.right.get(i+1)*50); }

println(in); }

void stop() { // always close Minim audio classes when you are done with them in.close(); minim.stop(); super.stop(); }

Best regards, uros
