我正在尝试使用 Java 从我的 Mac 上的麦克风录制音频。在 Google 上进行了一番搜索后,我在最底部找到了代码,但是当我在 Eclipse 中运行它时,每 3 或 4 次就有 1 次出现错误:

java(4946,0x1095f9000) malloc: *** error for object 0xd07400083: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

出现在控制台上。根据此处的另一篇文章,它与 Apple 为 OSX 提供的流氓库有关,但我不知道在 Java 中捕获音频的任何其他方式。有没有办法通过更改我正在使用的 Java 代码来防止这个错误,或者这超出了代码的范围?

这是我正在使用的代码:

import java.io.File;
import java.io.IOException;
import javax.sound.sampled.AudioFileFormat;
import javax.sound.sampled.AudioFormat;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.DataLine;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.TargetDataLine;


public class AudioCapture extends Thread
{
private TargetDataLine dataLine;
private AudioFileFormat.Type audioFileType;
private AudioInputStream incomingStream;
private File generatedFile;

public AudioCapture(TargetDataLine line,
        AudioFileFormat.Type requiredFileType,
        File file){
    dataLine = line;
    incomingStream = new AudioInputStream(line);
    audioFileType = requiredFileType;
    generatedFile = file;}

public void startCapture(){
    dataLine.start();
    super.start();}

public void stopCapture(){
    dataLine.stop();
    dataLine.close();}

public void run(){
    try{
        AudioSystem.write(
                incomingStream,
                audioFileType,
                generatedFile);}
    catch (IOException e){
        e.printStackTrace();}
}

public static void main(String[] args){
    String strFilename = "captureFile.wav";
    File outputFile = new File(strFilename);

    AudioFormat audioFormat = new AudioFormat(
            AudioFormat.Encoding.PCM_SIGNED,
            22050.0F, 16, 2,
            4, 22050.0F, false);
    DataLine.Info info = new DataLine.Info(TargetDataLine.class,
            audioFormat);
    TargetDataLine targetDataLine = null;
    try{
        targetDataLine = (TargetDataLine) AudioSystem.getLine(info);
        targetDataLine.open(audioFormat);}
    catch (LineUnavailableException e){
        System.out.println("Unable to acquire an audio recording line");
        e.printStackTrace();
        System.exit(1);}
    System.out.println("AudioFormat settings: " + audioFormat.toString());
    AudioFileFormat.Type targetType = AudioFileFormat.Type.WAVE;
    AudioCapture recorder = new AudioCapture(
            targetDataLine,
            targetType,
            outputFile);

    recorder.startCapture();
    System.out.println("Starting the recording now...");
    System.out.println("Please press to stop the recording.");
    try{
        System.in.read();}
    catch (IOException e){
        e.printStackTrace();}

    recorder.stopCapture();
    System.out.println("Capture stopped.");}
}

这是一个有点雄心勃勃的行动方案,但是:

你可以完全按照它所说的去做并调试它(这会有帮助吗?我不确定)。如果安装了 CDT 包,可以使用 gdb 调试编译。
