If you have ever bought a sound system, especially a surround sound system and tried wiring up the amplifier and working through the menu of features, you have probably come across things like - delay, speaker distance, test tone, phase, x-over, large or small speakers and a host of other choices and options. These are there for a reason, but are widely misunderstood, misused or, most commonly ignored.
If you are setting up an audio system, it is a pretty sure bet that you are not getting your money’s worth, no matter how good your sound system is. This is perfectly understandable. It is not easy and there are many things to consider. This is where you need audio calibration.
Small room acoustics are complex, so maximizing your audio system will take time, effort and the right test equipment. Imagine getting rid of that annoying boom or squeaky top end; being able to clearly hear every word spoken in a movie and being able to close your eyes and ‘see’ exactly where every sound is coming from. Even if you think your audio system is great, you will be stunned by the improvements after audio calibration.
There is a good chance your audio system is working hard generating sounds you can't even hear. They are there all right, but complex room ‘modes’ can mean that where you are sitting could be just the spot where there is nothing to be heard at specific frequencies. Audio calibration can help resolve that.
