The resulting two-channel signal is exported to an audio WAV file. In this simulation, a 1 kHz sine wave is switched in two-second intervals between CH1 and CH2. Figure 1 shows a circuit that generates a 1 V, 1 kHz sine wave and splits it into two channels, alternating the signal between them-the 1 kHz tone is switched in 2-second intervals between CH1 and CH2.įigure 1. Let’s start by producing a stereo wave file from a mono signal. It also illustrates a few tips and tricks with WAV files that will enable the reader to further utilize WAV files.

This article expands the discussion to stereo (or more channels), and shows how to export stereo data from, and import it to, LTspice via WAV files. Using mono LTspice audio WAV files is well documented. While it is fascinating to see a circuit come to life on the computer screen, creating a sound file that can be played outside of LTspice enables engineers to use another sense to evaluate simulations. LTspice has many superpowers, but its handling of audio files is one of its more impressive talents. This article details how to use LTspice audio WAV files for the less well-known syntax of stereo (and higher channel count). It is well documented that mono WAV files can be used as an input in LTspice, and LTspice can be used to produce a WAV output. LTspice can be used to generate WAV files as an output of a circuit simulation as well as import WAV files to excite a circuit simulation. This RAQ explains how to use LTspice ® audio WAV files for the syntax of stereo (and higher channel count). If music be the food of love, simulate on. LTspice Audio WAV Files: Using Stereo and Encrypting Voice MessagesĬan you utilize stereo data and encrypt voice messages with LTspice audio WAV files? Answer:
