Hello,

I'm fairly new to Ess so I'm hoping there's a simple solution to the following problem.

Basically, I'm filling an AudioInput buffer, then storing that audio data into an AudioChannel buffer of the same size. The problem is, when I attempt to record a second time, audioInputData() is not being called, leading me to believe that the recording engine is not cleared after stopping and starting the AudioInput. Is there a way to reset? Or is there an easier way to go about it? Feels like I'm missing a very basic concept. Thanks in advance!!

Here's the stripped-down code:


// mousePressed will begin recording
// keyPressed will play back recording from AudioChannel

import krister.Ess.*;

AudioInput myInput;
AudioChannel myChannel;

void setup() {
size(200,200);
background(100);
Ess.start(this);
myInput=new AudioInput(200000);
myChannel = new AudioChannel();
myChannel.initChannel(myChannel.frames(4536));  
frameRate(30);
}

void draw() {
}

void audioInputData(AudioInput theInput) {
println("audioInputData() called");
saveSound();
myInput.stop();
}

void saveSound(){
for(int i = 0; i < myInput.buffer.length;i++){
myChannel.samples[i] = myInput.buffer[i];
}
println("audio stored");
}

void audioChannelDone(AudioChannel ch) {
 println("audioChannelDone() called");
}

void mousePressed(){
println("start myInput");
myInput.start();
}

void keyPressed() {
 println("play myChannel");
myChannel.play();
}

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

ok, I have a new but related problem. When I attempt to record audio a second time (and every time after), there's a substantial lag time between calling myInput.start() and when the recording actually starts. I've also attempted using a completely different input for the second recording, but the lag time remains.

Has anyone else encountered this? Any ideas? Any help would be greatly appreciated!
