LTspice: Importing and Exporting WAV & PWL Text Files

Sometimes you may want to apply a voltage source to your circuit whose characteristics have been derived from an external source, whether it is a WAV file or a just a list of time and voltage instances.

This video will demonstrate how to import and export WAV audio files in LTspice, as well as how to read a list of piecewise linear values from a text file to create infinitely complicated stimulation voltages.
