you can run any windows sound application or DVD Player software above the Equalizer. The Equalizer will correct the audio stream automatic and will include the Limiter and the compressor to be sure, that the audio signal is not to loud or not to low.
If you load a wav file or a mp3 file you can hear the different and the effect of the Equalizer. You will be very impressed and you think that you have new sound speakers. All the playlist you have made, sounds now much better and you can use any sound application. Watch movies with nice bass sounds and a limiter to lower the loud passages. The compressor will made the low signal a little bit louder. Whhen Auto Correct is enabled, it will scan all selected frequencies in the wav file to determine the minimum and maximum amplitudes.It will then correct these variations by automatically increasing or decreasing the levels of attenuation at specific frequency intervals (usually 1/3 octave).The result is a nearly linear frequency response. For the listener, this creates more consistent sounding audio. A typical application that would benefit from this tool is an internet radio station. A common problem that many of these stations experience is an inconsistency in true audio reproduction (i.e., different songs sound different).
