我從InputStream獲取字節,但我需要修改並將它們保存到Wav文件。AudioSystem Write,AudioInputStream從InputStream獲得的修改字節,Java
這裏我的代碼:
套接字發送音頻從麥克風獲得。
AudioFormat adfmt = new AudioFormat(8000.0f, 8, 1, true , true);
int bufferSize = (int) adfmt.getSampleRate()* adfmt.getFrameSize();
byte[] buffer = new byte[bufferSize];
Socket clientSocketO = new Socket(...);
OutputStream output = clientSocketO.getOutputStream();
DataLine.Info dlInfo = new DataLine.Info(TargetDataLine.class, adfmt);
TargetDataLine tdLine = (TargetDataLine) AudioSystem.getLine(dlInfo);
tdLine.open(adfmt);
tdLine.start(); // start capturing
boolean bRunningO = true;
while (bRunningO) {
int count = tdLine.read(buffer, 0, buffer.length);
if (count > 0) {
byte[] outgoingBytes = Arrays.copyOf(buffer, count);
output.write(outgoingBytes);
}
}
tdLine.flush();
其另一端的Socket接收字節:
AudioFormat adfmt = new AudioFormat(8000.0f, 8, 1, true , true);
int bufferSize = (int) adfmt.getSampleRate()* adfmt.getFrameSize();
byte[] buffer = new byte[bufferSize];
Socket clientSocketI = new Socket(...);
InputStream input = clientSocketI.getInputStream();
String fileName = System.getProperty("file.separator") + "SomeFile.wav"
File fileStreamedWav = new File((new File("")).getAbsolutePath() + fileName);
AudioInputStream ais;
ByteArrayInputStream bis;
DataLine.Info dlInfo = new DataLine.Info(SourceDataLine.class, adfmt);
//SourceDataLine sdLine = (SourceDataLine) AudioSystem.getLine(dlInfo);
//sdLine.open(adfmt);
//sdLine.start(); // start playback
AudioFileFormat.Type afType = AudioFileFormat.Type.WAVE;
boolean bRunningI = true;
while (bRunningI) {
try {
int read = input.read(buffer); //Socket Reading bytes
byte[] incomingBytes;
if (read > 0) {
incomingBytes = Arrays.copyOf(buffer, read);
if (incomingBytes!= null) {
//sdLine.write(incomingBytes, 0, incomingBytes.length);
//Same Size bytes, but isn't necessary submit the put Code
byte[] changedBytes = MethodChangerBytes(incomingBytes);
bis = new ByteArrayInputStream(changedBytes);
ais = new AudioInputStream(bis, adfmt,
changedBytes.length/adfmt.getFrameSize());
int W = AudioSystem.write(ais, afType, fileStreamedWav);
System.out.println("AudioSystem.write:" + W);
}
}
} catch (IOException e) {
bRunningI = false;
}
}
這裏字節的代碼修改,對於現在假設由兩個放大...
byte[] MethodChangerBytes(byte[] incoming) {
byte[] outgoing = new byte[incoming.length];
for (int i = 0; i < incoming.length; i ++) {
// Really is not important what happens here
double Sample = (double)(short)(((incoming[i] - 128) & 0xFF) << 8);
Sample *= 2.0;
outgoing[i] = (byte)(((int()Sample >> 8) + 128) & 0xFF);
}
return outgoing;
}
當sdLine是註釋掉然後我可以在這裏傳送所有聲音。
的AudioInputStream(InputStream的流,AudioFormat的格式,長的長度)
AudioSystem.write(的AudioInputStream流,爲AudioFileFormat.Type的fileType,文件出)
問題:
此代碼僅保存從MethodChangerBytes獲取的最後字節。
問題:
如何保存處理的Wav字節的所有字節,直到Socket連接被關閉?
謝謝
