My project is related to sound, recording and playback the recording.
Every time I record a sound the sound is saved but when I try to record another sound there is not a new recording file but the second sound is saved in the first recording file.

Another thing that I want to achieve is to save the one recording file above the other (blended-merge sounds)

How can I achieve that?

This is what I have done so far:

/**

* Record Line In

* by Damien Di Fede.

*

* This sketch demonstrates how to an <code>AudioRecorder</code>

* to record audio to disk. To use this sketch you need to have

* something plugged into the line-in on your computer. Press 'r'

* to toggle recording on and off and the press 's' to save to disk.

* The recorded file will be placed in the sketch folder of

* the sketch.

String filename;

void setup()

{

size(512, 200, P2D);

textMode(SCREEN);



counter = 5;

filename = "myrecording" + counter + ".wav" ;



minim = new Minim(this);

// get a stereo line-in: sample buffer length of 2048

// default sample rate is 44100, default bit depth is 16

in = minim.getLineIn(Minim.STEREO, 2048);

// create a recorder that will record from the input to the filename specified, using buffered recording

// buffered recording means that all captured audio will be written into a sample buffer

// then when save() is called, the contents of the buffer will actually be written to a file

// the file will be located in the sketch's root folder.

recorder = minim.createRecorder(in, filename, true);







textFont(createFont("SanSerif", 12));

}

void draw()

{

//counter = counter + 1;

//filename = "myrecording" + counter + ".wav" ;



background(0);

stroke(255);

// draw the waveforms

// the values returned by left.get() and right.get() will be between -1 and 1,

// so we need to scale them up to see the waveform

for(int i = 0; i < in.bufferSize() - 1; i++)

{

line(i, 50 + in.left.get(i)*50, i+1, 50 + in.left.get(i+1)*50);

line(i, 150 + in.right.get(i)*50, i+1, 150 + in.right.get(i+1)*50);

}



if ( recorder.isRecording() )

{

text("Currently recording...", 5, 15);

}

else

{

text("Not recording.", 5, 15);

}

}

{

// to indicate that you want to start or stop capturing audio data, you must call

}



if ( key == 'k' ) kick.trigger();



if ( key == 's' )

{



// we've filled the file out buffer,

// now write it to the file we specified in createRecorder

// in the case of buffered recording, if the buffer is large,

// this will appear to freeze the sketch for sometime

// in the case of streamed recording,

// it will not freeze as the data is already in the file and all that is being done

// is closing the file.

// the method returns the recorded audio as an AudioRecording,

// see the example AudioRecorder >> RecordAndPlayback for more about that





recorder.save();

counter = 10;

filename = "myrecording" + counter + ".wav" ;



println("Done saving.");

//in.close();

//kick = minim.loadSample(filename, 2048);

I am trying to write a code which plays back the sound.
Do you know how can I achieve that?

This is what I have done but the processing always stacks when I run it.

Hi, I m working on the following code. I can do several records, and listen to them back. But I want to listen my recordings "blended to each other". How can I do that??

import pitaru.sonia_v2_9.*;

Sample mySampleObj;

void setup(){
size(400,200);
background(0,50,0);
Sonia.start(this);
LiveInput.start();
int recTimeSec = 10;
mySampleObj = new Sample(44100*recTimeSec);
}

void draw(){

}

void keyPressed(){
if(key == 'r'){
LiveInput.startRec(mySampleObj);
print("REC");
}

if(key == 's'){
LiveInput.stopRec(mySampleObj);
print("STOP");
}

if(key == 'p'){
mySampleObj.play();
print("PLAY");
}
}

public void stop(){
Sonia.stop();
super.stop();
}

Thanx
