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

  FT_REALTIME_POORAUDIOPROXY reads continuous data from the sound card using the
  standard Matlab API and writes it to a FieldTrip buffer. This proxy has poor timing
  and will produce dropped audio frames between blocks. Also the Matlab documentation
  warns about using this API for long recordings because this will fill up memory and
  degrade performance.
 
  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
    ft_realtime_pooraudioproxy(cfg)
 
  The audio-specific configuration structure can contain
    cfg.channel     = number of channels (1 or 2, default=2)
    cfg.blocksize   = size of recorded audio blocks in seconds (default=1)
    cfg.fsample     = audio sampling frequency in Hz (default = 44100)
    cfg.nbits       = recording depth in bits (default = 16)
 
  Note that currently, the sound will be buffered in double precision irrespective of the sampling bit depth.
 
  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
 
  Finally, there is an option for showing debug output
    cfg.debug       = show sample time and clock time (default = 'yes')
 
  To stop this realtime function, you have to press Ctrl-C
