#Module 8: Soundscape

How can we change the tune?

This week, I looked into the use of a free computer software called Audacity. Audacity is a program available for free download online, and is used for sound recording and editing audio files. Using the functions available in the program, you can also create a new sound of your own. The most common use of this program is for cutting, splicing, and mixing sound files to create your own tune. Sound files can also be edited using Audacity through features that allow you to change the speed, change the pitch, create an echo, and many other effects.

Although Audacity is free in terms of cost, the term free software refers to the freedom while using the program. The program is distributed to the public by the GPL (GNU General Public License) and is developed mainly by volunteers. Users of the program have the ability to use the program without any cost, they can study the codes and the functions in the program, and they can choose to help improve the program. This type of program is also known as an open source software. Programs like Audacity, Firefox, Apache, or OpenOffice are different examples where the source code can be accessed by anyone to use or study.

When using the program to create all new audio files, a user can begin by recording audio right in the application. Otherwise, the user can start with the generate tab. Using this menu, you can create sounds like white noise, chirps, or a click track. After a sound clip has been created, different effects can be used to change the pitch of the sound, the duration, or the tone. When all the editing is done, the audio can be exported as an mp3, wav, wma, or many other file formats.

Try the software out and see what you can create.

By clapping more or less, you can signal to us which stories really stand out.
