- WM Flange
- ─────────
-
- WM Flange does just what its name implies: given a WAV, it flanges it. If
- this explanation makes you no wiser, it may help to know that flanging is
- what makes Nirvana sound like Nirvana. Technically, flanging is done by
- mixing a sound with a delayed version of itself, with the delay undergoing
- a periodical variation. If the result is NOT fed back into the effect "box"
- (and provided that you choose a sufficiently small delay variation and a
- sufficiently slow effect rate) you get a chorus effect; with feedback the
- sound becomes REALLY warped, and you have flanging. WM Flange allows you to
- control all the relevant parameters.
-
- Tip: For stereo chorus/flange, use stereo source WAVs. Convert mono
- files to stereo with WM WAVmix {WAVmix} prior to flanging.
-
- Usage: Flange <source> <destination> <original level>:<effect level>
- <feedback> <time offset>:<time variation> <effect rate>
-
- The default directory is Temp\. The default extension is WAV. The
- source file may NOT be overwritten; you must specify different
- filenames and/or extensions.
-
- The <original level>:<effect level> pair consists of two real
- amplitude factors (use negative values for phase inversion).
-
- The feedback value (also real, with absolute value < 1) determines
- the "amount" of flanging; zero feedback is plain chorus.
-
- <time offset>:<time variation> control the delay (in milliseconds).
- <time offset> is the shortest delay time, <time offset>+
- <time variation> the longest delay time. True flange/chorus builds
- on the interference between similar sounds; making these values too
- large will destroy the effect. Start off with values in the range
- 0:1 - 0:10 milliseconds.
-
- <effect rate> is the period (in Hz) of the delay variation. Also
- here, small values are best. Try effect rates in the range 0.1 to
- 10 Hz first.
-
- Options: /l (affect left sound channel only - ignored if file is mono)
- /r (affect right sound channel only - ignored if file is mono)
- /w <start>:<end> (effect window times, in milliseconds)
- /q (quiet mode: no screen output)
-
- The following title:value pairs are written to WAVmaker's public Function key
- file {FnKeys} upon successful termination:
-
- File #1 : <source>
- File #2 : <destination>
- Parameter #1 : <original level>
- Parameter #2 : <effect level>
- Parameter #3 : <feedback>
- Parameter #4 : <time offset>
- Parameter #5 : <time variation>
- Parameter #6 : <effect rate>
-
- If the /w (effect window) option is used, the following pairs are also
- written:
-
- Start time : <start>
- End time : <end>
