- WM HighPass
- ───────────
-
- WM HighPass does just what its name implies: given a WAV, it performs high
- pass filtering on it, damping low frequencies. It can also amplify the end
- result (without precision losses) in order to compensate for the signal power
- being filtered out (/a <amplification> option).
-
- For those in the know, the algorithm employed is the standard one-pole
- filter.
-
- Usage: HighPass <source> <destination> <HHF>
-
- 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.
-
- HHF is short for Half Height Frequency, i.e. the frequency (in Hz)
- at which the amplitude factor will have fallen to 0.5 (from 1 at
- half the sampling frequency). Audio buffs will recognize this as the
- 3 dB point.
-
- Options: /l (affect left channel only)
- /r (affect right channel only)
- /a <amplification>
- /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 : <HHF>
-
- If the /w (effect window) option is used, the following pairs are also
- written:
-
- Start time : <start>
- End time : <end>
