- WM Echo
- ───────
-
- WM Echo does just what its name implies: given a WAV, it adds echo(es) to it.
-
- Usage: Echo <source> <destination> <feedback> <delay time>
-
- 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.
-
- <feedback> is a real parameter with absolute value < 1, controlling
- the echo level. A larger value yields more (and louder) echoes.
- Negative feedback values cause echoes to be phase inverted relative
- to the original signal. Setting <feedback> to zero yields no echoes
- at all.
-
- The delay time (the time between echoes) is given in milliseconds.
-
- 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)
-
- Note: The destination file size is always equal to the source file size.
- In order to avoid abrupt clipping of the echo effect, use WM Extend
- {Extend} to add a suitable silent section to the source before using
- WM Echo.
-
- 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 : <feedback>
- Parameter #2 : <delay time>
-
- If the /w (effect window) option is used, the following pairs are also
- written:
-
- Start time : <start>
- End time : <end>
