Filtering audio

Filter effects change the frequency content of audio, letting you adjust tonal range to
enhance audio or create special effects. (Be aware, however, that significantly boosting a
frequency can cause clipping.)
Using the Dynamic EQ effect
The Dynamic EQ effect varies the amount of equalization over time. For example, during
the first half of a waveform, you can boost high frequencies; during the second half, you
can change the bandwidth of affected frequencies. The Dynamic EQ dialog box provides
three areas of controls: Gain, Frequency, and Q (bandwidth).
