Audio sharing/editing software
In this section we will be reflecting on processes involved in recording, editing and sharing Audio files.
It's fairly easy to record, upload and share sound recordings through social web. But if you want to get the most out of audio, it's still worth while to install the open source audio- editor and -recorder Audacity. You can download Audacity from the SourceForge website. Make sure you install the correct version for your Operating System. Audacity alllows you to add sound to a project in 3 different ways:
If you record a voice you'll probably have to do some basic editing to clean up the waveform.
By now you have succeeded in recording audio in 3 different ways in Audacity. Using the Edit toolbar you have corrected slip of the tongues and other irregularities. But the recording is not ready to be published. If you listened to it now, you would immediately hear that some waveforms drown the other waveforms. All the audio tracks start at the same time, which makes it sound like a cacophony. Time to finetune the project by using the Tools toolbar.
If you save your Audacity project you are actually saving a file format .aup. This is very useful if you want to make changes in the original project later on but outside of Audacity this file format is useless. Exporting the file as an MP3, is the solution you're looking for.
An MP3 can be used in almost any digital application: Learning Objects, Learning Paths,(L)CMS like Chamilo and Moodle, Webquests, whiteboards, … Another option is to share the recording online via a streaming audio service.
Teachers have been using audio for many years to support their classes. Technology can help you to take audio a step further. It offers teachers the chance to enrich teaching materials with multimedia and give personalized feedback. A good podcast is an excellent tool to share concepts and information with your students. But audio can also be an engaging way to put your students to work. Here are two examples of using audio in the classroom from the Taccle2 website:
Audioboo offers a very similar service as Soundcloud. The interface is again very user-friendly and they have apps for Android, iOS (apple) en Nokia. They offer you a choice between recording and uploading. Audioboo doesn’t have a limit on the total amount of minutes you can use in your free account, but every Boo (recording) can last only 3 minutes. One of the advantages of Audioboo is that you can post your recordings automatically on sites like WordPress, Blogger and Tumblr, at least if you are prepared to give Audioboo access to your account details for these sites. It's great for an activity where students create Audioboo's outside the class and they see all the recordings appear on the class blog and can comment on each other's work.
If you're feeling ambitious, you might consider your own class radio show with Spreaker. Interested? Check this page to learn how to do it.
