Audition Tools

There is no substitute for recording clean audio tracks without background noise, but Audition does have some advanced tools for reducing unwanted sounds.

Noise Reduction and Hiss Reduction: This is a good place to start for any consistent background noises, such as a mechanical hum.

Sound Remover: This newer tool is capable of removing more complex sounds, such as sirens or ringtones.

This overview from Adobe explains additional techniques that may be useful.


Compared to the other Adobe programs used in this course, Adobe Audition is not as dominant in the professional software market. Users differentiate between DAWs — digital audio workstations — that can create complex sounds with many tracks, and more rudimentary audio editors that facilitate basic changes to existing audio files.

Note that you are required to use Adobe Audition for your COM210 assignments. However, you may want to explore other tools as a comparison.

Here are some additional audio editing programs to know about:

Avid Pro Tools: A standard among audio professionals for many years, Pro Tools is a complicated but sophisticated DAW that’s used in a range of industries including radio, sound mixing for video and music production. It’s also pricey, though also available on a subscription basis with updates like the Adobe programs. A simplified free version called First recently debuted for those who want to try it out.

Logic Pro: Available for Mac only, this is the more professional big sister of Apple’s GarageBand. Optimized for music production, it’s known for an intuitive interface and fairly affordable price point ($199).

Audacity: Free and open source, Audacity remains popular as a bargain audio editor with basic editing features that aren’t far behind more expensive software.

Reaper: Cheaper ($60 for most users) and more lightweight than some of the better-known DAWs, Reaper benefits from a strong community of users, especially among amateur and semi-professional music producers.

WavePad: For a less robust audio editing program, WavePad has been growing in popularity for its easy-to-use interface and “freemium” model, making most features available for free.
