A <b>Zero-average</b> filter adjusts each sample up or down so that the average of all
samples becomes zero.
<br><br>
A <b>Normalize</b> filter adjusts each sample to the maximum possible volume without adding distortion.
It also zeros popping signals that can occur during the first or last 6 milliseconds.
<br><br>
A <b>Low-pass</b> filter lets low-frequency sounds remain,
and tries to eliminate frequencies above a specified frequency.
For example, to eliminate high-pitched scratching sounds, use this with
the high frequency set to 12000 Hz.
<br><br>
A <b>High-pass</b> filter lets high-frequency sounds remain,
and tries to eliminate frequencies below a specified frequency.
<br>If the track has a low-pitched <i>hum</i>, try a high-pass filter with the lowest
frequency allowed set to 100.
<br><br>
A <b>Band-pass</b> filter lets sounds between the specified low and high
frequencies remain, trying to eliminate frequencies outside this band.
<br><br>
A <b>Band-stop</b> filter tries to eliminate sounds between the specified
low and high frequencies.
<br>
For example, to use this to eliminate a 60 Hz hum,
set the low frequency to 40, the high frequency to 80,
and set the Fast/Best slider to Best.
<br><br>
<b>Note</b> that all of these operations cannot be undone, so consider saving a copy
of your song before applying them. We will support Edit / Undo for these operations
in a future version. We will also be adding a real-time non-destructive EQ in a future version.
In the meantime, consider using Anvil Studio with DirectX EQ addins from other manufacturers.
