Cooledit a novice tutorial to eliminate the hissing sound

Eliminate the "hissing" sound generally to use the CE "Equalizer" function. First transferred into the "mute" after the accompaniment of the fate (accompaniment). mp3 ", select" Effect "→" filter "→" Parameter Equalizer ". This "parameter Equalizer" for beginners is not very intuitive, here is not very understanding of the equalizer friend can also choose to use the "graphic equalizer" to adjust, its operating interface than "parameter equalizer" intuitive much easier. Here we use "parametric equalizer" to eliminate the "hissing" sound in the accompaniment.

The function of "equalizer" is to enhance or attenuate the sound intensity of a certain frequency segment or some frequency segment. The "hissing" sound is usually around 8000Hz, and we're going to decay the sound intensity of the area.

The frequency response of the general human voice is mainly in the medium frequency, we can do appropriate attenuation to the if part. But the air sound and the tooth sound mainly in 6000hz-18000hz above, may also do the attenuation processing according to the actual situation, but may lose the accompaniment the clarity. Equalizer is generally used to do repair and optimization, the elimination of the human voice must rely on the "effect" → "waveform amplitude" → "Channel weight mixing shrink" to do
