The E-learning Curve at Edublogs

Having discussed a range of primary design and authoring tools, today’s post will look at one of the key content development tools, an open source non-linear audio editor (NLE) called Audacity.

[It] is an easy-to-use audio recorder and editor for Windows, Mac OS X, GNU/Linux, and other operating systems .

(sourceforge.net)

Audacity has the capability to record live sound, convert analogue media sources, and manipulate audio. Its functions include: 

• Export to digital recordings like podcasts or CDs
• Edit WAV, MP3, FLAC, and Ogg Vorbis sound files
• Cut, copy, splice, and mix multiple audio files
• Apply a range of digital signal processes including normalization, noise reduction, EQ, and compression

Audacity enables audio content may be exported in a wide range of formats, making it an exceptionally flexible tool for content developers. With a relatively shallow learning curve, the application can be used by non-experts after a few hours on instruction and use, while retaining the features found in proprietary NLEs  like Steinberg WaveLab and Sony Sound Forge for media developers .

This level of functionality enables both SME and specialist content developers to take advantage of the features in the application in an Open Environment for E-Learning.
