// This is an interface for the audio processing simulation utility. This
// utility can be used to simulate the audioprocessing module using a recording
// (either an AEC dump or wav files), and generate the output as a wav file.
// The |ap_builder| object will be used to create the AudioProcessing instance
// that is used during the simulation. The |ap_builder| supports setting of
// injectable components, which will be passed on to the created AudioProcessing
// instance. It is needed to pass the command line flags as |argc| and |argv|,
// so these can be interpreted properly by the utility.
// To get a fully-working audioproc_f utility, all that is needed is to write a
// main function, create an AudioProcessingBuilder, optionally set custom
// processing components on it, and pass the builder together with the command
// line arguments into this function.
// To see a list of all supported command line flags, run the executable with
// the '--help' flag.

// the one above, but which adds the option of receiving the input as a string
// and returning the output as an array. The first three arguments fulfill the
// same purpose as above. Pass the |input_aecdump| to provide the content of an
// AEC dump file as a string. After the simulation is completed,
// |processed_capture_samples| will contain the the samples processed on the
// capture side.
