Java产生声音

这是从Java
Sound
提取（并简化）的一个小示例-示例：生成音频的代码

    byte[] buf = new byte[ 1 ];;    AudioFormat af = new AudioFormat( (float )44100, 8, 1, true, false );    SourceDataLine sdl = AudioSystem.getSourceDataLine( af );    sdl.open();    sdl.start();    for( int i = 0; i < 1000 * (float )44100 / 1000; i++ ) {        double angle = i / ( (float )44100 / 440 ) * 2.0 * Math.PI;        buf[ 0 ] = (byte )( Math.sin( angle ) * 100 );        sdl.write( buf, 0, 1 );    }    sdl.drain();    sdl.stop();
