ABSTRACT
A key component of audio engineering is to fully understand the analog model of signal flow, that is, how sound travels from the beginning to the end of its audio path. Much of audio engineering is troubleshooting different issues that occur during music production. Understanding signal flow can help people quickly pinpoint and solve a problem in order to keep a session running smoothly. To understand signal flow people will need to review and become familiar with the following terms: pre-amp, mic, line, input ready, tape send, tape return, stereo bus, I/O, Analog-to-Digital converters and speakers/monitors. There are many ways to record music. Music can be recorded with a separate mixer and multi-track recorder, or on a laptop with an audio interface. One of the easiest ways to get a live recording is to take a pair of stereo outputs from the main mixing console, known by engineers as "getting a split off the board".
