Effects
Selected Region
All of the effects described below apply only to the selected
region. To mark the selected region you can either click and
hold down on the wave window and drag the mouse or press and
hold down the shift key while moving in the file. To select
the entire file press Ctrl+A. If you do not have any region
selected when accessing an effect, the entire waveform will
be selected as default.
Presets
Some effects come with a series of options known as "Presets".
The idea behind presets is to save you having to fiddle around
with the numbers, which is great if the numbers don't mean a
lot to you. Instead, you can just browse the preset list and
select the option which best describes the effect you are trying
to achieve.
Amplify
To 'amplify' is to increase the loudness or volume of the selected
region. To make a part of the recording softer or louder, select
it and then use the menu Effects -> Amplify. The volume is entered
in percent (100 being no change, 50 being -6dB softer or 200
being +6dB louder).
Normalize
To 'normalize' is to adjust the volume so that the loudest peak
is equal to (or a percentage of) the maximum signal that can
be used in digital audio. Usually you normalize files to 100%
as the last stage in production to make it the loudest possible
without distortion.
High-Pass Filter
A high-pass filter (sometimes called a low cut filter) removes
all low frequencies below a specified Hz. This is useful if
you want to make your recording sound 'clearer' or less 'muddy'.
It is very usual to use a high-pass filter of about 300Hz on
all voice recordings to improve intelligibility.
Equalizer
An equalizer changes the frequency response of a signal so it
has different tonal qualities. See General Audio Concepts (Samples,
Channels etc..) for some explanation about what this means.
After you select Effects menu -> Equalizer you will see a graph
of amplitude against frequencies. Left click on any slider bar
to create a new band point.
To assist you with shaping the Equalizer graph in the way you
want, there is a preset list that displays the most common sorts
of filters used in the Equalizer graph. You can choose any preset
filter from the list and then manipulate the filter to achieve
the effect you desire.
If you are using the equalizer simply to drop lower frequencies,
you should always try the High Pass filter first (Effects menu
-> High Pass Filter), because it is better and faster for very
low frequencies.
Echo
You can use this function to create single echoes, as well as
a number of other effects. Delays of 35 milliseconds (ms) or
more will be perceived as discrete echoes, while those falling
within the 35-15 ms range can be used to create a simple chorus
or flanging effect. (These effects will not be as effective
as the actual chorus or flanging effects, as the delay settings
will be fixed and will not change over time).

Reverb
Reverb is many small reflections of the sound that come after
a set time. It usually occurs when someone is speaking in a
room, hall etc. More reverb is called wet, no reverb is called
dry.
For more information about flanging effect see: http://www.harmony-central.com/Effects/Articles/Reverb/
Duration
The delay time, in ms.
Mix Depth
The dry is the volume of the input signal and the wet is the
volume of the delayed signal, in percent. Varies from 0 to 100.
If Mix Depth = 0 result signal isn't contain delayed signal.
If Mix Depth = 100 result signal isn't contain input signal.
Other values of Mix Depth are combination of the dry and the
wet (wet = 100 - dry).
Feed Back Gain
The feedback sets how much delay is feed back to the input.
Varies from 0 to 100.
Reverb Gain
The level of reverberation signal in db.
Tap Delay
The number of taps before delay is fed back to the input.
Reverb Frequency
The type of trim. Can be one of the following types: trim from
left, right or from both sides of trim level.
Reverse
This effect reverses the selection in the same way playing a
record or tape backwards would.
Fade In
Fade Out
Fade Out and Trim
To fade in or out use the menu Effects -> Fade In or Effects
-> Fade Out.
The fade out and trim option is a combined function which fades
out over the selection then marks the end of the selection as
the end of the file. This is frequently used at the end of music
tracks.
Envelope
The 'envelope' is the change in volume of the select region
over time. This can be used to make fine adjustments to the
volume over time or even more crude changes like fade in or
fade out.
Select the region you want to change the volume over and use
the menu Effects -> Envelope. Click on any point to adjust its
volume.
Speed Change
Normal speed changes changes the pitch in proportion to the
speed. If you want to change the speed but keep the pitch the
same use this function.
Pitch Change
This changes the pitch of the recording without changing the
speed (i.e. the converse of the above).
Dynamic Range Compressor
A Dynamic Range Compressor limits the volume levels of a sound
recording so that it stays within a certain loudness range.
An example of where it is used is in TV broadcasting, where
it ensures that the volume levels of ads are perceived as being
louder than the television program itself (without any change
in the actual broadcast volume).
It also has a use for recording audio from one medium to another,
where the two mediums are not capable of handling the same range
of volume levels (e.g. A CD can handle a much greater range
than a cassette tape)
The "Threshold" setting works by detecting when the sound recording
volume exceeds a defined decibel level. It then gradually attenuates
the sound to bring it down below the dB level, and does it in
such a way that the listener will not be aware the attenuation
is occurring.
Flanger
Flanging is created by mixing a signal with a slightly delayed
copy of itself, where the length of the delay is constantly
changing. It is actually one specific type of phasing (Phaser).

Delay Rate
Rate of delay. Varies from 0 (there isn't delay) to 100 (delay
is 20 ms).
Mix Depth
The dry is the volume of the input signal and the wet is the
volume of the delayed signal, in percent. Varies from 0 to 100.
If Mix Depth = 0 result signal isn't contain delayed signal.
If Mix Depth = 100 result signal isn't contain input signal.
Other values of Mix Depth are combination of the dry and the
wet (wet = 100 - dry).
Feed Back Gain Feed Back Gain sets how much delay is feed back
to the input. Varies from 0 to 100.
Sweep Depth The sweep depth determines how wide the sweep is
in terms of delay time, in percent. Varies from 0 (no effect)
to 100 (maximal effect).
Sweep Rate This parameter refers to the frequency of flanging.
Varies from 0 to 100, in percent.
Sweep Phase
Phase of delay, in radian.
Reverb
It is the sound you hear in a room with hard surfaces where
sound bounces around the room for a while after the initial
sound stops.

The number of taps before delay is fed back to the input.
Reverb Frequency
The type of trim. Can be one of the following types: trim from
left, right or from both sides of trim level.
Chorus
The Chorus differs from the Flanger in only a couple of ways.
One difference is the amount of delay that is used. The delay
times in a Chorus are larger than in a Flanger, usually somewhere
between 20 ms. and 30 ms. (the Flanger's delay usually ranges
from 1 ms. to 10 ms.) This longer delay doesn't produce the
characteristic sweeping sound of the Flanger. The Chorus also
differs from the Flanger in that there is generally no feedback
used.
