A DEMO to show how to display a waveform using standard text mode Python. "pyaudio" must be installed for this to work. Levels are set using the standard audio mixers, (System Preferences -> Sound).</p> <p>Just whistle a signal of say 300Hz to 3KHz, (normal voice spectrum), using say, the internal mic, and watch a waveform appear inside the X-Y graticule.</p> <p>Read the code for more information.</p> <p>$VER: SimpleScope_OSX.py_Version_0.00.10_(C)2012_B.Walker_G0LCU.</p> <p>This code is GPL2, but, the hardware information is Public Domain.</p> <p>(I am looking into including Windows and Linux variants too using pyaudio to access the sound system.)</p> <p>Enjoy finding simple solutions to often very difficult problems.</p> <p>Bazza, G0LCU...</p>
