我正在嘗試編寫一個讀取wav文件併發送輸出的小程序,就好像它會來自我的麥克風一樣。不幸的是,我對聲音API沒有多少經驗。模擬麥克風輸入
背景:我基本上試圖實現的是一個程序,當我在聊天室(即Teamspeak,Ventrilo)時播放聲音。爲了讓它現在可以工作,我必須將錄音設備切換到「您聽到的聲音」,播放聲音然後切換回麥克風。該程序應模擬來自麥克風的輸入。
到目前爲止,我只能播放聲音。我想我只需要一個不同的SourceLine?
public class Player {
private final int BUFFER_SIZE = 128000;
private AudioInputStream audioStream;
private AudioFormat audioFormat;
private SourceDataLine sourceLine;
public void playSound(File soundFile) {
try {
audioStream = AudioSystem.getAudioInputStream(soundFile);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
audioFormat = audioStream.getFormat();
DataLine.Info infoIn = new DataLine.Info(SourceDataLine.class,
audioFormat);
try {
sourceLine = (SourceDataLine) AudioSystem.getLine(infoIn);
sourceLine.open(audioFormat);
} catch (LineUnavailableException e) {
e.printStackTrace();
System.exit(1);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
sourceLine.start();
int nBytesRead = 0;
byte[] abData = new byte[BUFFER_SIZE];
while (nBytesRead != -1) {
try {
nBytesRead = audioStream.read(abData, 0, abData.length);
} catch (IOException e) {
e.printStackTrace();
}
if (nBytesRead >= 0) {
@SuppressWarnings("unused")
int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
}
}
sourceLine.drain();
sourceLine.close();
}
}
解決方案: 安裝VB音頻線(http://vb-audio.pagesperso-orange.fr/Cable/)。這是捐贈軟件。製作VB輸出標準錄音設備。在麥克風屬性中選擇VB-Input作爲播放。
public class Player {
private final int BUFFER_SIZE = 128000;
private AudioInputStream audioStream;
private AudioFormat audioFormat;
private SourceDataLine sourceLine;
public void playSound(File soundFile) {
try {
audioStream = AudioSystem.getAudioInputStream(soundFile);
} catch (Exception e) {
e.printStackTrace();
System.exit(1);
}
audioFormat = audioStream.getFormat();
DataLine.Info infoIn = new DataLine.Info(SourceDataLine.class,
audioFormat);
try {
Mixer.Info[] mixerInfos = AudioSystem.getMixerInfo();
Mixer mixer = null;
for (int i = 0; i < mixerInfos.length; i++) {
System.out.println(mixerInfos[i].getName());
if (mixerInfos[i].getName().equals(
"CABLE Input (VB-Audio Virtual Cable)")) {
mixer = AudioSystem.getMixer(mixerInfos[i]);
break;
}
}
sourceLine = (SourceDataLine) mixer.getLine(infoIn);
sourceLine.open(audioFormat);
} catch (LineUnavailableException e) {
e.printStackTrace();
System.exit(1);
}
sourceLine.start();
int nBytesRead = 0;
byte[] abData = new byte[BUFFER_SIZE];
while (nBytesRead != -1) {
try {
nBytesRead = audioStream.read(abData, 0, abData.length);
} catch (IOException e) {
e.printStackTrace();
}
if (nBytesRead >= 0) {
@SuppressWarnings("unused")
int nBytesWritten = sourceLine.write(abData, 0, nBytesRead);
}
}
sourceLine.drain();
sourceLine.close();
}
}
我很困惑;你的意思是「好像它會來自我的麥克風」? –
