Hi,

Using the alternet library for networking I can't sent a string from client to server or vice versa if the string contains special characters such as umlauts. There are a number of places that suggest converting the string to a byte array and then converting back to a string afterwards. I have tried to find examples of this but I can't seem to find any that work for me.

In my client I have

      String sometext = "some string";

      try
      {
      byte[] lineData = wholeLine.getBytes("UTF-8");
      }
      catch (UnsupportedEncodingException e)
      {
          println(e.getMessage());
      }
      client.send(lineData);

But it never sends as it doesn't seem to recognise the ("UTF-8") section of the code. When I remove the catch() it always says UnsupportedEncodingException.

How can I convert a UTF8 string to byte array and send to the server?

How does it get reconverted afterwards?
The server will sent to all the clients afterwards so I presume it gets reconverted when returned to the clients.

I'm struggling with this one. Anyone?

I have included in my code the mousewheel listener event from the Processing wiki

I am setting up a collaborative text editor with 32 computers.

Hi,

Hi, I have a large text file. Each line looks something like this:

I am just starting to use supercollider and processing with p5_sc library and I am having trouble creating multiple buffers. I want to play several sound samples using different buffers but I can only create 1 buffer which must be named "playbuf_1"

My porcessing code is:

import oscP5.*;
import netP5.*;

import supercollider.*;

Buffer buffer;

void setup ()
{
  Buffer buffer = new Buffer(2);
  buffer.read("C:\\Voices/voice1s.wav");
  Synth synth = new Synth("playbuf_1");
  synth.set("bufnum", buffer.index);
  synth.create();
}

void mousePressed()
{
  buffer.free(this, "freed");
}

My supercollider code is:

SynthDef(\playbuf_1, { |bufnum = 0, outbus = 0, amp = 0.5, loop = 0, rate = 1.0|
    var data;
    data = PlayBuf.ar(2, bufnum, BufRateScale.kr(bufnum) * rate, 0, 0, loop);
    FreeSelfWhenDone.kr(data);
    Out.ar(outbus, data * amp);
}).store;


This code works fine - my sample plays.

The strange thing is when I rename the buffer in both SC and Processing to anything else (e.g. playbuf_2) the
buffer will not play in SC. I get an error post saying:

*** ERROR: SynthDef playbuf_2 not found
FAILURE /s_new SynthDef not found
FAILURE /n_set Node not found

Why is this?
If I want to use multiple samples I assume I will need more than the one buffer. How can I rename the buffer to have multiples samples playing?

Any help appreciated.

Hi,
I have been using this class code to access the FreeTTS API  and can access some of the features of voice manipulation. I would like to save the synth stream to file but I'm struggling to do this.
I know I have all the FreeTTS files and Mbrola correctly installed as I can hear the speech synth working.
But when I try to save to file by using SingleFileAudioPlayer I cant seem to find the wave file - it doesn't seem to be saving it.

Here is the code, I have highlighted the suspect code in red:


import com.sun.speech.freetts.Voice;
import com.sun.speech.freetts.VoiceManager;
import com.sun.speech.freetts.audio.JavaClipAudioPlayer;
import com.sun.speech.freetts.audio.SingleFileAudioPlayer;
import javax.sound.sampled.AudioFileFormat;

public class Basnik {
  String voiceName = "us2";
  float Pitch = 20.0;
  float pitchShift = 20.0;
  VoiceManager voiceManager;
  Voice voice;

   
  Basnik(String name, float pitch, float pitchshift){
    pitchShift = pitchshift;
    Pitch = pitch;
    voiceName = name;    
    this.setup();
  }
 
  void listAllVoices() {
    System.out.println();
    System.out.println("All voices available:");     
    VoiceManager voiceManager = VoiceManager.getInstance();
    Voice[] voices = voiceManager.getVoices();
    for (int i = 0; i < voices.length; i++) {
    System.out.println("    " + voices[i].getName()
      + " (" + voices[i].getDomain() + " domain)");
    }
  }

  void setup() {
    listAllVoices();
    System.out.println();
    System.out.println("Using voice: " + voiceName);

    voiceManager = VoiceManager.getInstance();
    voice = voiceManager.getVoice(voiceName);
    voice.setAudioPlayer(new SingleFileAudioPlayer("C:\\max.wav",javax.sound.sampled.AudioFileFormat.Type.WAVE));
    voice.setRate(30.0);
    voice.setPitch(Pitch);
    voice.setPitchShift(pitchShift);
    voice.setPitchRange(200.1); //mutace
    voice.setStyle("casual");  //"business", "casual", "robotic", "breathy"

    if (voice == null) {
    System.err.println(
    "Cannot find a voice named "
      + voiceName + ".  Please specify a different voice.");
    System.exit(1);
    }   
    voice.allocate();
  }

  void mluv(String _a){    

    if(_a==null){
    _a= "nothing";
    }
    voice.speak(_a);

  }

  void exit(){
    voice.deallocate(); 
  }
}


The main code for the programme is then

Basnik verlaine ;

void setup(){
 System.setProperty("mbrola.base","C:\\mbrola");
 verlaine = new Basnik("mbrola_us3",20.0,20.0);
 verlaine.mluv("I'm finding this difficult") ;
}



Why is the file not saving? I have tried various permutations of the file name C:\max, C:\max.wav etc..
Please help!

Hi, I have been messing with processing for 3 days now. Very new to programming...

I am trying to work with Roborealm robotic vision software.

Here's how I hoped it works...

Processing accesses a text file that includes a string array of data in multiples of 12 numbers - each set of 12 providing data for each object identified by Roborealm - the length of this string is variable depending on how many objects the vision software identifies

At setup (), 20 'Circle' objects are created to place data in. 

A Timer class creates a loop every 6400 ms.

In draw(), at the end of the timer loop, data from the file is added to the Circles objects, to then be used to create imagery and sound

Problem -

I keep getting The constructor 'Timer' is unidentified, with reference to the line in setup () , timer = new Timer(6400)

What am I doing wrong?

As far as I can tell the Timer class seems to be constructed properly?

Please help!

Here is the code

Circles [] circles;
Timer timer;
String numbers= join(loadStrings("test2.txt")," ");//loads in file and joins strings into one
int[] nums = int(split(numbers, " "));//converts string to integer array


void setup() {
  size (640,480);
  timer = new Timer(6400);//starts a timing loop
  timer.start();
  for (int i = 0; i < 20; i++) {
      //initialise 20 circle objects
      circles [i] = new Circles(0,0,0,0,0,0,0);
    }
} 

void draw() {
background();
if (timer.isfinished());//end of the timer loop
  {
  for (int i = 0; i < (nums[].length/12); i++){ //put data into active objects
    circles[i].Xpos = nums[i*12];
    circles[i].Ypos = nums[i*12+1];
    circles[i].Rad = nums[i*12+2];
    circles[i].Standev = nums[i*12+3];
    circles[i].ColR = nums[i*12+4];
    circles[i].ColG = nums[i*12+5];
    circles[i].ColB = nums[i*12+6];
    }
  for (int i = nums[].length/12; i < 20; i++){//put zero data into inactive objects (see Circles class / deactivate
    circles[i].deactivate;
    }
  timer.start(); //restart the timer
  }
}

//define Circles class
class Circles {
 
  int xpos;
  int ypos;
  int radius;
  int standev; //standard deviation of circle colour;
  int colourr; //mean red colour of circle
  int colourg; // '' green
  int colourb; // '' blue
  Timer timer;
 
  //Circles Constructor
  Circles(int Xpos, int Ypos, int Rad, int Standev, int ColR, int ColG, int ColB)
    {
    xpos = Xpos;
    ypos = Ypos;
    radius = Rad;
    standev = Standev;
    colourr = ColR;
    colourg = ColG;
    colourb = ColB;
  }

  //void display() {
  //to display imagery...
  //}

  //void sound() {
  //to make sound...

  void deactivate() {
    xpos = 0;
    ypos = 0;
    radius = 0;
    standev = 0;
    colourr = 0;
    colourg = 0;
    colourb = 0;}
  }
}


class Timer {
 
  int savedTime; // When Timer started
  int totalTime; // How long Timer should last
  int passedTime;
 
  Timer(int tempTotalTime) {
    totalTime = tempTotalTime;
  }
 
  // Starting the timer
  void start() {
    // When the timer starts it stores the current time in milliseconds.
    savedTime = millis();
  }
 
  // The function isFinished() returns true if 6,400 ms have passed.

    // Check how much time has passed
    int passedTime = millis()- savedTime;
