Do you ever need to edit audio content for your Moodle course? If so you should investigate Audacity!
Audacity is free, open source, cross-platform audio software for audio recording editing.
We love Audacity because it is FOSS, and available for Windows, Mac, and Linux !
There are far too many features to list here, but you can view them at http://www.audacityteam.org/about/features/
In Moodle courses, if you are recording your voice, music, or taking audio from other sources, Audacity will quickly let you produce the final file – usually an .mp4 format is best for Moodle / web delivery.
You can quickly apply EQ, Compression, Normalisation, and even removal of clicks and long silences ! Or ‘bounce’ audio to mono … and instantly reduce the file size by 50%. Then optimise for web delivery … and you have a clean, crisp audio fie that is maybe just 10% the size of the original recording – your learners will thank you !
There is a slight learning curve when you start with Audacity, partly because there are so many advanced and flexible options. But if you still to the basics at first, you can quickly achieve professional level results for your audio 🙂
In fact, we use Audacity to produce the free Moodle Podcast – so we stand by our words here !
