有一个java库可以同时录制N个频道吗？我有一个带有 8 个输入通道的 USB M-Audio Fast Track Ultra R8。我使用此代码列出了所有设备：
Mixer.Info [ ] = mixerInfo AudioSystem.getMixerInfo ();
System.out.println ( "Available mixers :");
for (int cnt = 0; cnt < mixerInfo.length ; cnt + + )
{
System.out.println ( mixerInfo [ cnt ] . GetName ());
}
获取此列表：
Available mixers :
Audio Driver main
Speakers (Realtek High Definition Audio )
Output ( 2 - M- Audio Fast Track Ultra 8R )
Primary driver of acquisition sounds
Microphone ( Realtek High Defini
Stereo Mix ( Realtek High Defini
Input ( 2 - M- Audio Fast Track Ul
Port Speakers ( Realtek High Defined
Port Stereo Mix ( Realtek High Defini
Port Microphone ( Realtek High Defini
Port Output ( 2 - M- Audio Fast Track U
Port Input ( 2 - M- Audio Fast Track Ul
我希望看到 8 个输入通道，但我只看到一个。我只能从一个频道录制。如何访问所有频道？
