Linux 上で Java を使用してオーディオ ファイルをスクリプト化する方法

java -version

clip.open(audioInputStream);
clip.start();

Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);

long startFrame = clip.getMicrosecondPosition();
// 在此处设置截取的起始时间、结束时间

long endFrame = clip.getMicrosecondPosition();

clip.setMicrosecondPosition(startFrame);
clip.stop();

AudioFormat format = clip.getFormat();
AudioInputStream shortenedStream = new AudioInputStream(clip, format, endFrame - startFrame);

AudioSystem.write(shortenedStream, AudioFileFormat.Type.WAVE, new File("audio-cut.wav"));

AudioInputStream processedStream = processAudio(audioInputStream); // 在此处调用你自定义的音频处理方法

AudioSystem.write(processedStream, AudioFileFormat.Type.WAVE, new File("audio-processed.wav"));
