The flanger and chorus are very similar and are different in few aspects. One of them is how many times the delay is applied. The number of delay times in a flanger is smaller than that in a chorus, the range of which is commonly set from 1 ms and 10 ms. This induces a “sweeping” sound. To apply this effect, click the button Flanger to set the parameters or choose the presets offered: Blur, Classic/Crying/Deep Slow Flanger, Fast Sweeping Loop, Flanger-Vibrato and Light Chorus.
Flanging is an audio effect produced by mixing two identical signals together, with one signal delayed by a small and gradually changing period, usually smaller than 20 milliseconds. This produces a swept comb filter effect: peaks and notches are produced in the resultant frequency spectrum, related to each other in a linear harmonic series. Varying the time delay causes these to sweep up and down the frequency spectrum. A flanger is an effects unit dedicated to creating this sound effect.
Step 1. Add flanger effect
To add a flanger effect, you firstly need to launch MP3 Editor for Free and add an audio file to the waveform window. Then click “Effect” tab and choose “Flanger” to specify detailed parameters or apply some popular presets to adjust the effect. Click “Preview” to listen to the music before adding the effects to the waveform to make sure you get exactly what you want. Click “OK” to add the flanger effect to the selected region.
