    compressor上面有兩個參數attack和release,
    請問像attack調大,是compressor的作用時間變快還是變慢?
    release應該是compressor off的時間吧?是不是調高,到off的時間就變長?

    Attack & Release 的參數應該是"快" or "慢"..."Fast" or "Slow"....not big or small..

    Attack:
    how fast the gain is reduced in response to an increase in input signal level above the threshold ...
    Too fast results in unnatural fluctuations in the signal dynamic and distortion of low frequency signals as the compressor attempts to "ride" the wave form .... too slow lets the high level signal through before the compressor has time to react.....
    Faster times are useful in limiting applications,... slower times are useful in compression applications....

    Release:
    How fast the gain is restored to normal levels after the input signal falls below the threshold ....
    Too fast and the output signal is "choppy" or "jittery" as the gain is changed rapidly ..... too slow results in unwanted lowering of the gain of low level portions of the signal due to sluggishness of response balance between fast and slow unwanted ducking after a high level portion of signal.....

    謝謝了!
    這個我了解,但是就是不知道attack數值調高是compressor作用變快還變慢,
    因為我搞混了聲音的attack....就是說像小鼓的attack很快,如果要壓掉一些,應該是attack數值調高還是調低?
    我想應該是調低吧....

    要壓掉一些?壓Peak ?還是縮小dynamic ?
    越低是越快的意思嗎?
    attack 快慢跟threshold 的位置的配合關係很大...不能只看單個..
