Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_realtime_signalproxy”.

  FT_REALTIME_SIGNALPROXY creates some random data and writes it to a FieldTrip buffer.
  The FieldTrip buffer is a network transparent server that allows the acquisition
  client to stream data to it. An analysis client can connect to read the data upon
  request. Multiple clients can connect simultaneously, each analyzing a specific
  aspect of the data concurrently.
  Use as
  with the following configuration options
    cfg.blocksize            = number, in seconds (default = 0.5)
    cfg.channel              = cell-array with channel names
    cfg.fsample              = sampling frequency
    cfg.speed                = relative speed at which data is written (default = 1)
    cfg.precision            = numeric representation, can be double, single, int32, int16 (default = 'double')
  The target to write the data to is configured as
    cfg.target.datafile      = string, target destination for the data (default = 'buffer://localhost:1972')
    cfg.target.dataformat    = string, default is determined automatic
  You can apply some filtering to the random number data to make it
  appear slightly more realistic with
    cfg.lpfilter      = 'no' or 'yes'  lowpass  filter (default = 'no')
    cfg.hpfilter      = 'no' or 'yes'  highpass filter (default = 'no')
    cfg.bpfilter      = 'no' or 'yes'  bandpass filter (default = 'no')
    cfg.lpfreq        = lowpass  frequency in Hz
    cfg.hpfreq        = highpass frequency in Hz
    cfg.bpfreq        = bandpass frequency range, specified as [low high] in Hz
