A “Flanger” effect changes a sound signal by introducing a short, cyclically varying delay into one or more copies of the signal and recombining them. This produces a sweeping comb filter effect, which typically sounds like a “swooshing” effect. Some versions of the effect, including this plug-in, include an option to feed a portion of the delayed signal back into the effect.
- Maximum delay (ms): [0 to 10 (default = 1)] The maximum amount of delay applied as the signal passes through the effect
- Sweep range: [0 to 10 (default = 8)] The range of variation in delay time. At zero, the delay is a constant amount equal to the maximum delay. At 10 the delay amount cycles between no delay and maximum delay.
- Speed (Hz): [0 to 10 (default = 1)] The speed at which the delay cycles between maximum and minimum delay times (cycles per second).
- Feedback: [0 to 10 (default = 0)] Increasing the feedback passes a greater amount of the processed signal back to the input. At zero, the signal will pass through the effect once only. At higher values, the signal will pass through the effect multiple times in progressively smaller amounts.
- Dry Mix: [-10 to +10 (default = -8)] The amount of “dry” (unprocessed) signal that is mixed with the processed signal. At zero, only the processed signal is returned, producing a cycling Doppler type effect. At negative values, the dry signal is inverted before being mixed with the processed signal.
- Width (stereo tracks only): [0 to 10 (default = 0)] When a stereo track is processed, increasing the “width” setting causes the delay cycle in the right channel to be shifted relative to the left channel. At zero, the delay of both left and right channels move in unison, so that both channels are at maximum delay at the same time, and at minimum delay at the same time. At maximum “width”, the left channel is at maximum delay when the right channel is at minimum delay, and vice verse, creating a sense of wide stereo separation.
- Increasing the feedback amount increases the amount of processing, and so increases the processing time. Feedback amounts below 4 have little effect. The increase in perceived effect of feedback diminishes above about 6, with little noticeable difference in effect between a setting of 7 and 10, other than the time taken to process. When feedback is required, settings of around 5 tend to give a reasonably strong effect without impacting too severely on processing time.
- For a strong effect, use either “Feedback” or “Dry mix”. Using both at the same time tends to mask the overall effect. Using both together can be useful for more subtle effects.
- The overall level of the output will often be less than the input level. This is intentional so as to ensure that the overall level is not increased to the point of distortion. If necessary, use the Amplify effect after applying the Flanger to boost the overall level.
- Use the Preview button to preview the effect before applying. The result of this type of effect can be difficult to predict, so experimentation is encouraged.
- Flanger effects tend to be most effective on sounds that are rich in harmonics.
- For short delay times, adding a negative amount of “Dry Mix” will tend to give a stronger sweep in the treble frequencies and reduce the bass.
