Audio Editing Software Terms and Definitions
Audio Editing
All programs should include play, record, cut, copy, paste and so on;
this rating goes beyond the basic editing tools to include tools such
as equalizers, processors, mixers, preset effects, filters as well as
analyzing tools like the waveform or spectrogram.
Recording/Editing Ability
The best products have the ability to "record" sounds saved
on the computer from a file, the sound card or from downloaded CDs as
well as from outside sources such as a line-in from a stereo or a microphone.
It is also nice if the product includes burning software so that users
can use their CD or DVD burner to save their edited audio files.
To be the most compatible, the product must be able to work with and
convert many file formats, like the various WAV file types, OGG Vorbis
or MPEG as well as Windows Media Audio (WMA).

Ease of Use
All major features of the product should be easy to find and use. It
is helpful if the product contains preset effects and filters placed
in the drop down menus, mouse zooms, right click edits and unlimited
undos. Quick recorders that look for sound cards or streaming audio,
without manually having to set the source is also a nice feature.
Help and Support
Audio editing software can be hard for inexperienced audio editors and
non-professional mixers to master. Comprehensive help and support offered
through FAQs, direct contact to technical support, user forums, help
pages or other documentation makes learning to use editing software
a snap.
Editing Tools
Batch Processing/ Conversions
This command or tool is used to convert a set of files from one format
to another and/or to apply effects to a set of files.
Channel Mixer
Used to swap, mix, invert, or combine left and right channels.
Cue Points
Used to mark and describe or hold information pertaining to a specific
position of an audio track. For example, a cue point can hold information
about a singer or artist or can mark and hold looping points.
Effect Chain Editor
This tool enables the editor to chain a number of effects together to
process at one time.
Effect Preview
Before saving a new edit, this preview will play and display the changes
before implementation.
Equalizer
A device or computer algorithm that increases/decreases the volume of
specific bands of frequencies in an audio signal.
Format Converter
Many programs have the ability to convert file formats, for example
from a WAV PCM signed 16 bit stereo file to a MPEG Audio (mp3) Layer-3
ACM 44100Hz 128 kbps joint stereo file.
Frequency Tuner
Similar to an equalizer or a parametric equalizer, it is used to adjust
frequencies.
Labels and Regional Markers
May also be referred to as a bookmark, it can mark or label a specific
time location in an editor window.
Meta Information Editor
Enables editors to enter or edit artist, title, album, year, genre or
other information of the selected file.
Mixer
A device or algorithm, which enhances or directs audio signals to other
destinations, singly or together. May also be used to combine selections,
for example a techno music file with an audio voice file to create a
new techno mix.
Mouse Scroll Zoom
A handy feature that allows users to select a section of the waveform
and use the mouse scroll to zoom in and out.
Parametric EQ
An electronic filter that adjusts frequency, attenuation, amplification
and bandwidth on each parametric channel, which can all be used simultaneously
or individually bypassed.
Processor
A device used to alter the dynamic properties of the recording.
Punch In/Out
The process of re-recording sections of a previously recorded track,
starting a punch may be called "punching in" and ending a
punch "punching out."
Right Click Edits
Features accessible through the right click button of a mouse, that
may include such functions as play, copy, paste or zoom.
Signal Analysis Tools
Tools used to analyze audio signals as they travel through audio cables,
equipment or other system.
Track Splitter
Many programs have the ability to separate the tracks into left and
right channels, whereas others, depending on the file type, have the
ability to break apart multi tracks.
Variable Speeds
Increases or decreases the playback speed.
Audio Effects
Amplify
Changes volume or loudness.
Chorus
An effect in which multiple copies of a signal are played together slightly
off time from each other.
Compressor
Reduces the dynamic range of a signal, making loud sounds quieter and
the quiet sounds louder.
Crossfade
Fades out one sound while fading in another.
Delay
An effect in which a copy of a signal is played back later than the
original.
Doppler
Dynamically changes a pitch.
Dynamics
Volume changes in audio.
Echo
A delay-based effect where copies of a signal are introduced then trail
off to silence.
Expander
Reduces the level of a signal when it falls below a set threshold in
order to overemphasize its dynamic range.
Fade In/Out
Changes level over time increasing/decreasing in amplitude from/to silence.
Feedback
Delayed repeated signal that produces multiples of the original signal.
Or, a loud squeal created when a channel is receiving its own output.
Flange
Generates a swirling sound by adding a slightly delayed copy of a signal
in which the delay time fluctuates.
Harmonizer
Can add odd and even multiples of a fundamental frequency to provide
a characteristic (or timbre) to give each instrument or voice a unique
sound.
Invert
Changes positive offset to negative and vice versa.
Interpolate
Smoothes out the waveform between start and finish markers, often used
to remove a pop or click.
Mechanize
Adds a robotic or mechanical characteristic.
Modulate
An electronic process, in which one source modifies the characteristics
of another signal source.
