Expand description

Starts the audio recording via cpal on the given audio device (or the default input device), opens a GUI window and displays two graphs. The upper graph is the latest audio input as wave form (live/real time). The lower graph can be customized, to show for example a spectrum or the lowpassed data.

This operation is blocking. It returns, when the GUI window is closed.

This operation is expensive and will be very laggy in “Debug” builds!

Parameters

  • name Name of the GUI window
  • preferred_height Preferred height of GUI window. Default is DEFAULT_H.
  • preferred_width Preferred height of GUI window. Default is DEFAULT_W.
  • preferred_x_range Preferred range for the x-axis of the lower (=custom) diagram. If no value is present, the same value as for the upper diagram is used.
  • preferred_y_range Preferred range for the y-axis of the lower (=custom) diagram. If no value is present, the same value as for the upper diagram is used.
  • x_desc Description for the x-axis of the lower (=custom) diagram.
  • y_desc Description for the y-axis of the lower (=custom) diagram.
  • preferred_input_dev See AudioDevAndCfg.
  • audio_data_transform_fn See open_window_connect_audio.
