示例1: calculateSamples
import javazoom.spi.mpeg.sampled.file.MpegAudioFileReader; //导入依赖的package包/类
public static int calculateSamples() throws UnsupportedAudioFileException, IOException{
File file = new File(fileDialogs.getInputPath());
AudioFileFormat baseFileFormat = new MpegAudioFileReader().getAudioFileFormat(file);
Map properties = baseFileFormat.properties();
Long duration = (Long) properties.get("duration");
int samples = (int) (duration/1000/1000)*44100;
return samples;
}
示例2: decode
import javazoom.spi.mpeg.sampled.file.MpegAudioFileReader; //导入依赖的package包/类
@Override
public AudioInputStream decode(File inputFile) throws UnsupportedAudioFileException, IOException {
