### Example Usage
|
|
|
|
```java
|
|
import processing.sound.*;
|
|
import soundtrack.optical.*;
|
|
|
|
SoundtrackOptical soundtrack;
|
|
|
|
String soundtrackFile = "../../data/barking.wav";
|
|
int dpi = 2400;
|
|
float volume = 1.0;
|
|
String type = "dual variable area";
|
|
String pitch = "long";
|
|
boolean positive = true;
|
|
|
|
void setup() {
|
|
size(213, 620, P2D);
|
|
frameRate(24);
|
|
soundtrack = new SoundtrackOptical(this, soundtrackFile, dpi, volume, type, pitch, positive);
|
|
}
|
|
|
|
void draw () {
|
|
soundtrack.draw(0, 0);
|
|
}
|
|
```
|
|
|
|
### Alternate usage
|
|
|
|
Use the `frame(int x, int y, int frameNumber)` method to draw specific frames--used for laying out multiple frames of soundtrack on a single screen.
|
|
|
|
```java
|
|
void draw () {
|
|
soundtrack.frame(0, 0, frameCount);
|
|
}
|
|
|
|
```
