WavePad Audio Editor Software is an audio and music editor for Windows and Mac (also available for iOS and Android). It lets users record and/or edit music, voice and other audio recordings. As an editor, users can cut, copy, paste, delete, insert, silence, and auto-trim recordings, then add effects like amplify, normalize, equalize, envelope, reverb, echo, reverse, and more with the help of VST plugin support and a free stock audio library.

Microsoft Windows is a group of several graphical operating system families, all of which are developed, marketed and sold by Microsoft. Each family caters to a certain sector of the computing industry. Active Microsoft Windows families include Windows NT and Windows IoT; these may encompass subfamilies, e.g. Windows Server or Windows Embedded Compact. Defunct Microsoft Windows families include Windows 9x, Windows Mobile and Windows Phone.

macOS Operating system for Apple computers

macOS is a series of graphical operating systems developed and marketed by Apple Inc. since 2001. It is the primary operating system for Apple's Mac family of computers. Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS, after Microsoft Windows.

iOS mobile operating system by Apple

iOS is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that presently powers many of the company's mobile devices, including the iPhone, iPad, and iPod Touch. It is the second most popular mobile operating system globally after Android.

NCH Software software development company in Canberra, Australia

NCH Software is an Australian software company founded in 1993 in Canberra, Australia. The Colorado office was started in April 2008 due to the large U.S. customer base. NCH Software primarily sells to individuals via its website.

CNET American media website about technology and consumer electronics

CNET, formerly Computer Network, is an American media website that publishes reviews, news, articles, blogs, podcasts and videos on technology and consumer electronics globally. Founded in 1994 by Halsey Minor and Shelby Bonnie, it was the flagship brand of CNET Networks and became a brand of CBS Interactive through CNET Networks' acquisition in 2008. CNET originally produced content for radio and television in addition to its website and now uses new media distribution methods through its Internet television network, CNET Video, and its podcast and blog networks.


The primary functions and tools of WavePad are: [3]

Amplifier electronic device that can increase the power of a signal

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal. It is a two-port electronic circuit that uses electric power from a power supply to increase the amplitude of a signal applied to its input terminals, producing a proportionally greater amplitude signal at its output. The amount of amplification provided by an amplifier is measured by its gain: the ratio of output voltage, current, or power to input. An amplifier is a circuit that has a power gain greater than one.

Audio normalization is the application of a constant amount of gain to an audio recording to bring the amplitude to a target level. Because the same amount of gain is applied across the entire recording, the signal-to-noise ratio and relative dynamics are unchanged.

In telecommunication, equalization is the reversal of distortion incurred by a signal transmitted through a channel. Equalizers are used to render the frequency response—for instance of a telephone line—flat from end-to-end. When a channel has been equalized the frequency domain attributes of the signal at the input are faithfully reproduced at the output. Telephones, DSL lines and television cables use equalizers to prepare data signals for transmission.

Use in Education

As indicated by author Victor C.X. Wang/Florida Atlantic University in his book Handbook of Research on Education and Technology in a Changing Society, [7] WavePad's Free Trialware Version is more than adequate for educational institution use. WavePad is linked or referenced for download on many notable university websites for students requiring complex audio manipulation [8] (note 2016 WavePad is now a Free Trialware Version). NCH Software offers Academic pricing. [9]

Shareware is a type of proprietary software which is initially provided free of charge to users, who are allowed and encouraged to make and share copies of the program. Shareware is often offered as a download from a website or as a compact disc included with a magazine. Shareware is available with most computer software. Shareware differs from open-source software, in which the source code is available for anyone to inspect and alter; and freeware, which is software distributed at no cost to the user but without source code being made available.


Previously, WavePad and other NCH products came bundled with optional browser plugins like the Ask and Chrome toolbars, which sparked complaints from users and triggered malware warnings from antivirus software companies like Norton and McAfee. NCH has since unbundled all toolbars in all program versions released after July 2015. [10]

A browser toolbar is a toolbar that resides within a browser's window. All major web browsers provide support to browser toolbar development as a way to extend the browser's GUI and functionality. Browser toolbars are considered to be a particular kind of browser extensions that present a toolbar. Browser toolbars are specific to each browser, which means that a toolbar working on a browser does not work on another one. All browser toolbars must be installed in the corresponding browser before they can be used, and require updates when new versions are released.

Ask.com search engine

Ask.com is a question answering–focused e-business founded in 1996 by Garrett Gruener and David Warthen in Berkeley, California.

Google Chrome Web browser developed by Google

Google Chrome is a cross-platform web browser developed by Google. It was first released in 2008 for Microsoft Windows, and was later ported to Linux, macOS, iOS, and Android. The browser is also the main component of Chrome OS, where it serves as the platform for web apps.
