Your ears are the most important tool you have as a sound engineer, producer, or musician. And the best thing about them is they are FREE! They don’t require any software, measuring microphones, or computers. They are with you wherever you go.
I’m not saying that computer based tools and other measurement devices are not worthwhile, but they are just tools and should only be used as such. The problem comes when you start relying on those tools to tell you how things sound. After a while you just stop using your ears or simply forget to ‘listen’.
When I was very young I learned how to play piano by ear. I was actually pretty good at it until I started taking piano lessons. Once I learned how to read music somehow my ability to pick things up by ear got lost. It seemed much easier to get the sheet music for whatever song I wanted to learn rather than spend the time plunking away at the keyboard to figure out my favorite tune. But soon I started to regret it, not the learning how to read music part but losing the ability to play by ear. It took some work to regain that ability but I was glad I did. It made me a better player.
You don’t have to be born with perfect pitch, super human hearing, or an unlimited budget for gear to put together a great sounding mix. If you take the time to train your ears you’ll never be in a situation where you don’t have what you need to EQ the system, get rid of feedback, or simply get the sounds you want.
In live sound, there are all kinds of devices and software and tools for analyzing and optimizing the system. It’s important to note that they are just tools and in the wrong hands- someone who has not been properly trained to use them correctly they can do more harm than good. They also can be rather expensive and if you are just getting started in live sound, they may likely be out of your budget.
You might argue that you can specify that they be provided by the production, but again depending on the size/level of the gig, they might be out of the budget. However if you learn how to use and trust your ears you’ll always have what you need to EQ a system. You will never have anyone tell you it’s not in the budget…unless you’re not in the budget!
If you’re a recording musician, with trained ears you’ll be able to get the sounds you want and do your own mixing, saving you the expense of hiring someone else to handle those details.
Take care of your ears, train them and learn how to trust them!
