大约一年前,我开始开发一个Android应用程序。现在当我尝试运行它时,出现了有关AudioInputStream类的异常。通过使用谷歌进行短暂的研究后,我发现android不再支持这个类了。是否有任何替代方法呢?
以下是我编写的代码:
private void merge2WavFiles(String wavFile1, String wavFile2, String newWavFilePath) {
try {
File wave1 = new File(wavFile1);
if(!wave1.exists())
throw new Exception(wave1.getPath() + " - File Not Found");
AudioInputStream clip1 = AudioSystem.getAudioInputStream(wave1);
AudioInputStream clip2 = AudioSystem.getAudioInputStream(new File(wavFile2));
AudioInputStream emptyClip =
AudioSystem.getAudioInputStream(new File(emptyWavPath));
AudioInputStream appendedFiles =
new AudioInputStream(
new SequenceInputStream(clip1, emptyClip),
clip1.getFormat(),
clip1.getFrameLength() + 100
);
clip1 = appendedFiles;
appendedFiles =
new AudioInputStream(
new SequenceInputStream(clip1, clip2),
clip1.getFormat(),
clip1.getFrameLength() + clip2.getFrameLength()
);
AudioSystem.write(appendedFiles, AudioFileFormat.Type.WAVE, new File(newWavFilePath));
} catch (Exception e) {
e.printStackTrace();
}
}
