Question

我正在尝试使用UDP协议将matlab中的音频流传输到多个设备

matlab中的此代码使用UDP协议将音频从matlab发送到另一台设备

初始化

% Initialize several configuration parameters.
useMicrophone   = false;
IP_address      = '127.0.0.1';
IP_port         = 30000;
sampleRate      = 44100;
nChannels       = 1;
freq            = [100 99];
samplesPerFrame = 512;

% Create System objects to send local information to a remote client.
if useMicrophone
    % NOTE: audioDeviceReader requires an Audio Toolbox (TM) license
    localSource = audioDeviceReader('SampleRate', sampleRate,...
        'NumChannels', nChannels); %#ok<UNRCH>
else
    localSource = dsp.SineWave('SampleRate', sampleRate,...
        'Frequency', freq(1:nChannels),...
        'SamplesPerFrame', samplesPerFrame);
end
remoteSink = dsp.UDPSender('RemoteIPAddress', IP_address, ...
    'RemoteIPPort', IP_port);

% Create System objects to listen to data produced by the remote client.
remoteSource = dsp.UDPReceiver('LocalIPPort', IP_port,...
    'MaximumMessageLength', samplesPerFrame,...
    'MessageDataType', 'double');
localSink  = audioDeviceWriter('SampleRate', sampleRate);

流处理循环

fiveSeconds = 5*sampleRate;
for i=1:(fiveSeconds/samplesPerFrame)
    % Connect the local source to the remote sink.
    % In other words, transmit audio data.
    localData = localSource();
    remoteSink( localData(:));

    % Connect the remote source to the local sink
    % In other words, receive audio data.
    remoteData = remoteSource();
    if ~isempty(remoteData)
        localSink(remoteData);
    end
end

任何人都有一个想法，我如何才能使用UDP在php中接收此声音并在localhost中播放它
