私の友人と私は、java7 サウンドシステムが 6 つのチャネルをサポートし、さまざまなビットなどを使用するすべてのバリエーションをサポートしていることを知りました。
Java でできることをリストするコードは次のとおりです。
Mixer.Info[] mi = AudioSystem.getMixerInfo();
for (Mixer.Info info : mi) {
System.out.println("info: " + info);
Mixer m = AudioSystem.getMixer(info);
System.out.println("mixer " + m);
Line.Info[] sl = m.getSourceLineInfo();
for (Line.Info info2 : sl) {
System.out.println(" info: " + info2);
Line line = AudioSystem.getLine(info2);
if (line instanceof SourceDataLine) {
SourceDataLine source = (SourceDataLine) line;
DataLine.Info i = (DataLine.Info) source.getLineInfo();
for (AudioFormat format : i.getFormats()) {
System.out.println(" format: " + format);
}
}
}
}
これは、USB 接続の外部サウンド カードを使用した私の MacBook Pro からの出力です。
