    There are times when you would want to record audio from streaming video which can’t be downloaded. A free program that allows you to record audio from streaming video is Freecorder not to mention its ability to download YouTube videos and convert AV formats.

    The catch though is you need to install a toolbar in your web browser (Internet Explorer or Firefox). This would not really be an issue if you need a `one-stop’ centre to listen to Internet radio stations, view Internet TV, apart from undertaking the AV-related tasks mentioned above.

    The toolbar is tested to be spyware and adware free and has a download size of 10.4MB. The only drawback of installing the Freecorder toolbar is it takes up a little space on your web browser interface.

    Now, let’s look at how you could record streaming audio via Freecorder. To get started, you hit the Record Audio button when the online video starts playing. If you don’t have a fast Internet connection and have to wait for videos to buffer, you may want to play the videos fully before replaying them to ensure audio can be recorded without a hitch. Recorded audio will be saved as MP3. A tutorial on recording audio from the web is provided at the developer’s website.
