javascript - 我可以使用Java音频通过ALAudioDevice(setClientPreferences，然后进行订阅)从Pepper的麦克风流式传输音频吗？

Question

我已使用python成功将Pepper麦克风的音频流传输到笔记本:

 class SoundReceiverModule(naoqi.ALModule):
    .......
    def start( self ):
        audio = naoqi.ALProxy( "ALAudioDevice", self.strNaoIp, 9559 );
        nNbrChannelFlag = 3; 
        nDeinterleave = 0;
        nSampleRate = 48000;
        audio.setClientPreferences( self.getName(),  nSampleRate, nNbrChannelFlag, nDeinterleave ); 
        audio.subscribe( self.getName() );  

    def processRemote( self, nbOfChannels, nbrOfSamplesByChannel, aTimeStamp, buffer ):
        aSoundDataInterlaced = np.fromstring( str(buffer), dtype=np.int16 );
        aSoundData = np.reshape( aSoundDataInterlaced, (nbOfChannels, nbrOfSamplesByChannel), 'F' );
    .......

但是，当我使用Javascript进行操作时，订阅ALAudioDevice后没有产生信号。谁能帮我解决这个问题？谢谢!

目前，我无法对此进行测试，但是我希望这可以作为起点。请让我知道是否可行，否则您会遇到任何错误。

class SoundReceiverModule {
    constructor(){
    }
    processRemote(nbOfChannels, nbrOfSamplesByChannel, buffer, timeStamp){
        console.log(buffer)
    }
}

const channels = 3;
const deinterleaved = 0;
const sampleRate = 48000;
const moduleName = SoundReceiverModule.name;

// with /libs/qimessaging/2/qimessaging.js included
QiSession.connect(function (session) {
    session.service("ALAudioDevice").then(function (ALAudioDevice) {
        ALAudioDevice.setClientPreferences(moduleName, sampleRate, channels, deinterleaved);
        ALAudioDevice.subscribe(moduleName);
    });
});
