Hello,
I have an Arduino project for which I’m trying to downsample an mp3 track. To do so, I came across Processing and similar project. However, this is the error that I’m stuck with “The variable “BufferedAudio” does not exist” Any help is appreciated. Thanks!
`import java.awt.datatransfer.;
import java.awt.Toolkit;
import javax.swing.JOptionPane;
import ddf.minim.;
int SAMPLES = 30000;
Minim minim;
AudioSample sample;
void setup()
{
size(512, 200);
String file = selectInput("", “”);
if (file == null) {
exit();
return;
}
try {
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();
minim = new Minim(this);
sample = minim.loadSample(file);
float[] samples = sample.getChannel(BufferedAudio.LEFT);
float maxval = 0;
for (int i = 0; i < samples.length; i++) {
if (abs(samples[i]) > maxval) maxval = samples[i];
}
int start;
for (start = 0; start < samples.length; start++) {
if (abs(samples[start]) / maxval > 0.01) break;
}
String result = "";
for (int i = start; i < samples.length && i - start < SAMPLES; i++) {
result += constrain(int(map(samples[i], -maxval, maxval, 0, 256)), 0, 255) + ", ";
}
clipboard.setContents(new StringSelection(result), null);
JOptionPane.showMessageDialog(null, "Audio data copied to the clipboard.", "Success!", JOptionPane.INFORMATION_MESSAGE);
} catch (Exception e) {
JOptionPane.showMessageDialog(null, “Maybe you didn’t pick a valid audio file?\n” + e, “Error!”, JOptionPane.ERROR_MESSAGE);
}
exit();
}
void stop()
{
sample.close();
minim.stop();
super.stop();
}`
