Agitators and mixers are essential equipment for the professional sound engineer, but sometimes they can take over your life if you’re not careful. They can cause you so much stress that you never seem to have time to sleep. In this article, I will describe how agitators and mixers can cause a professional sound engineer to be obsessive compulsive.
The word agitator comes from the Greek roots, “agga” meaning an apple or a piece of fruit and “ti” meaning touch. As far as we know, there is no specific fruit that can be used as an agitator, but there are some common fruits that can be used to “stretch” the sound waves and get the sound waves to resonate and vibrate. I won’t go into the technical details of why the sounds resonate and vibrate, but it’s an interesting science that needs more research.
Now, if we use an agitator to spread the resonance of a sound wave and get it to resonate, what does that mean? We have created an odd, but very useful device, that is able to reproduce sounds that we couldn’t make on our own. An agitator and mixer will allow a music producer to hear something that they couldn’t see or hear before. That’s not all!
By using an agitator, we now have an extra tool that can give us more options and will allow us to create more complex sounds. The tool is so versatile that we can use it in many different ways. Using an agitator, we can create a thicker, richer sound. We can also control the sound of an instrument without actually touching the instrument itself.
How do we apply the agitator to the drum mixer? We use the agitator and mixer to spread the resonance of the drum sound over several metal sheets. To make sure that the sound is uniform, we put the metal sheets at different distances apart and then set the agitator up where the layers meet.
Then we use the metal sheets to send sound waves through the agitator, giving us a solid, clear sound. Sounds are amplified, but not at full force. We then add the resonant air while repeating the drum beat repeatedly.
By sending sound waves through the agitator, we’ve multiplied the strength of the sound with a medium and now we are able to project it into the audience. This allows us to project music onto a PA system and project it onto a sound stage. This also allows us to use multiple microphones at once.
Sound effects, complex ambiences, sound quality, and even live instruments can be reproduced from many angles. However, if the instruments aren’t close enough together, the sound doesn’t resonate and the instruments become “distorted”. By using an agitator and mixer, we have the ability to make “artificial sound” of any shape or form by varying the distance between instruments and making sure the agitator has been positioned correctly.
