Audio Effects
- Amplify Increase -
Increase volume on selected part of audio file
- Amplify Decrease -
Decreases volume on selected part of audio file
- Fade In - Creates a
fading in (soft to loud) effect in the selected part of an audio file.
- Fade Out - Creates a
fading out (loud to soft) effect in the selected part of an audio file
- Normalize - Normalization
allows you to achieve the greatest amount of amplification that will not result in
clipping (distortion). All parts of the wave are amplified at equal levels.
For example, if the loudest peak of a waveform is at 80% and the quietest peak is at 20%,
normalizing the file to 100% results in the waveformกฏs new loudest peak being 100%, and its new quietest
peak being 40%.
- Chorus - Just as a chorus is a group of singers, the chorus effect can make a
single instrument sound like there are actually several instruments being played. It adds
some thickness to the sound, and is often described as 'lush' or 'rich'.
- Delay - Delay can be used to
create single echoes, as well as a number of other effects. Delays of 35 milliseconds or
more will be perceived as discrete echoes, while those falling within the 15-34
millisecond range can be used to create a simple chorus or flanging effect.
By reducing the delay times further down into the 1-14 millisecond range, you can
spatially locate a mono sound (a sound with the same information for both the left and
right channels) so that it appears as though the sound is coming from the left or the
right side, even though the actual volume levels for left and right of the wave are
identical.
- Invert - This effect
flips the audio samples upside-down. This normally does not affect the sound of the audio
at all. It is occasionally useful, for example when the left and right channels of a song
both contain equal amounts of vocals, but unequal amounts of background instruments. By
inverting one of the channels and not the other, the vocals will cancel each other out,
leaving just the instrumentals. Obviously this only works if the exact same vocal signal
is present in both of the channels to begin with.
Inverting doesn't produce an audible effect, but it can be useful in lining up
amplitude curves when creating loops or pasting. If applied on a stereo waveform, both
channels are inverted.
- Reverb - Reverberates selected part of an
audio file.
- Reverse - Select this
command to have the current selection play backwards by reversing the order of its
samples. Reverse is useful for creating special effects. This effect reverses the selected
audio; after the effect the end of the audio will be heard first and the beginning last.
Some people reverse small portions of audio to make inappropriate language unintelligible,
while others believe you can hear subliminal messages if you listen to speech backwards.
You can also create interesting sound effects by recording natural events and reversing
the audio.
- Flanger - Applies
Flanging effect to the selected part of an audio file.
- Expander - Adds expander effect to the audio
data array.
- Compressor - Reduces the dynamic range of a
signal.
- Phaser - The name "Phaser" comes from "Phase Shifter",
because it works by combining phase-shifted signals with the original signal. The movement
of the phase-shifted signals is controlled using a Low Frequency Oscillator (LFO).
- Trim - Adds trim effect to the selected part
of an audio file.
- Silence - Inserts
a silence on selected part of audiofile
- Vibrato - Makes a
Vibrato effect in the selected part of an audio file.
- Pitch Shift - Changes the frequency of the
selected part of an audio file.
- Resample - Decreases or increases the rate
of the selected part of an audio file.
- Stretch Time - Makes a
Stretch effect in the selected part of an audio file, changing the pitch and duration.
