我正在尝试在 windows 和 android 之间发送音频,我成功地将 windows 发送到 windows 但是当我从 android 流式传输音频时,它只会产生白噪声。我认为这是 android 和 Windows 中的 AudioFormat 的问题,因为我猜当我将示例 Bits 更改为 8 时,我在耳机的一侧听到了声音,但随后它也消失了。
在安卓端
int BUFFER_MS = 15; // do not buffer more than BUFFER_MS milliseconds
int bufferSize = 48000 * 2 * BUFFER_MS / 1000;
AudioTrack audioTrack = new AudioTrack(AudioManager.STREAM_MUSIC, 48000, 2,
AudioFormat.ENCODING_PCM_16BIT, bufferSize, AudioTrack.MODE_STREAM);
byte[] buffer = new byte[bufferSize];
int bytesRead;
audioTrack.play();
while (socket.isConnected()) {
bytesRead = inputStream.read(buffer, 0, buffer.length);
audioTrack.write(buffer,0,bytesRead);
}
在 Windows 端
AudioFormat format = getAudioFormat();
DataLine.Info info = new DataLine.Info(TargetDataLine.class, format);
// checks if system supports the data line
if (!AudioSystem.isLineSupported(info)) {
throw new LineUnavailableException(
"The system does not support the specified format.");
}
TargetDataLine audioLine = AudioSystem.getTargetDataLine(format);
audioLine.open(format);
audioLine.start();
byte[] buffer = new byte[BUFFER_SIZE];
int bytesRead;
while (socket.isConnected()) {
bytesRead = audioLine.read(buffer, 0, buffer.length);
outputStream.write(buffer,0,bytesRead);
}
和 getAudioFormat 功能是
AudioFormat getAudioFormat() {
float sampleRate = 48000;
int sampleSizeInBits = 16;
int channels = 2;
boolean signed = true;
boolean bigEndian = true;
return new AudioFormat(sampleRate, sampleSizeInBits, channels, signed,
bigEndian);
}
只听到白噪音,如果有人可以帮忙,请做。
