Last Friday I ordered a microphone from Make it Louder so that I can see where I can improve my sound system for competition.
This device is supposed to be very accurate and able to withstand decibel levels up to 186 DB. You can use this device with just a multimeter or you can download their free software and use it’s real time anylizer. They also have a paid version of the software that allows a closer look at a more precise display of frequecies.
As soon as I get a chance I will give a report on this equipment.
