Easy Audio Tools are a set of virtual audio measuring instruments.
Our goal is to make audio measurement easy, but precise and as closer to the professional equipment with the same purpose.
Personal computers are way stronger machines than the embedded computers in the nowadays spectrum analyzers, oscilloscopes, etc. If we add some very good internal audio card to our PC, or external audio interface with 124 dB S/N ratio or better, and we have a PC application designed for audio measurement, we will have a very serious measuring instrument that will work as good as professional instruments that cost several thousand dollars.
On the other hand, if we have a normal small tablet PC with the internal audio that can provide, for example, 88 dB S/N ratio, we can also accomplish a very successful measurement of room acoustics, check a design of our handmade speaker system, fine tune parts in the crossover inside a speaker box, or tune a guitar...
