![]() ![]() Since you now know what signal flow is, why it’s important and how it works for both recording and mixing, go ahead and put your newfound knowledge to the test! It’s also essential to have a firm grasp of your signal flow so you are better-able to effectively and easily troubleshoot when needed. In a nutshell, understanding audio signal flow is important if you want to produce high-quality recordings and mixes. After the audio signal is adjusted to the correct level and amplified, audio then flows through the DAW to the audio interface, where it travels out of the mixer through headphones or speakers as sound. Inserts are then used to insert things like compression, EQ and effects into the signal pathway. However, when it comes to signal flow while mixing, the audio signal is sent to the mixing console’s channel via USB. For the output stage, the processed digital signal is converted back to physical sound where it then moves from the audio interface to speakers or headphones. To recap, you get the input stage where the sound source (either vocals or instrument) is picked up by the microphone, pre-amplified, converted to digital audio and then sent as data to your computer. You’ve already learned about signal flow while recording in the section above. So it’s important to know how these two things compare. Often audio signal flow comes into play either recording or mixing. Finally, the recorded sound reaches your ears or the audience through either headphones or out a speaker. Here, it’s converted to analog or sound by the D/A converter. For starters, the processed digital signal goes back from your DAW through your USB to the audio interface. For the output stage, the process is sort of reversed. Once the process is over, you’ll have digital data, which you can then copy to a hard drive, SSD, flash drive, etc. The digital signal is processed by the DAW. In the audio interface, the mic preamp amplifies the mic level signal, while the A/D converter converts the microphone signal into a format that your computer can recognize. The physical vibrations travel through the air and are picked up by the mic. The sound source can be an instrument or a vocalist whose voice produces physical vibrations. Here’s a breakdown of a very standard live sound signal flow: As shown in the image below, you’ll be dealing with - at the very least - a few basics: a mic, audio interface, computer and headphones. ![]() So, let’s take a look at the simplest signal flow for recording to get started. Truly understanding audio signal flow is much easier if you can visualize the signal flow path. A proper, full understanding of how audio signal flow works means you can save both face and time! It’s pretty clear that knowing the signal flow of your setup is a big deal, especially when you consider that problems are prone to occasionally happen from time to time when you’re dealing with audio. Understanding signal flow when mixing means you’re more likely to get the best sound quality, since you’ll be able to optimize the order of your effects. This is especially true if you’re dealing with a large set up and multiple components. Worse, your actions might even end up being counterproductive, causing a longer recovery time before you’re back in business. If you don’t know where to look, it means you’ll waste valuable time trying to troubleshoot and fix the problem. Signal flow matters because it’s all about knowing where to look when those inevitable issues pop up (for example, if the signal doesn’t reach the desired output). In some instances, signal flow can easily be traced by simply walking through the steps of your audio set up.īut what happens when something goes wrong and you can’t quickly identify the problem? Generally, the signal flow of your setup will vary based on whether you’re recording or mixing music - and understanding your flow is key to solving any problems that may arise. Imagine sound coming in from one end (the source), and then making a few stops along the way before it reaches your ears. Think of sound as having to flow and travel from, say, a mic, before it gets to the speakers or headphones. In other words, sound has to travel through different stages of your system, starting with the input and ending with the output. Signal flow is the path sound travels before you hear it. Here, we’re breaking down all the essential parts of signal flow you need to know to fully understand the important role it plays in audio. Understanding how signal flow works can help you troubleshoot and fix technical problems faster when recording or mixing music. ![]()
