The other day, I needed to record some speech in my own voice and burn it to an audio CD that I could listen to in my car. I was actually learning some lines for an important presentation, so it seemed like a good way to practice.

The voice recorder app that's built into Windows 10 was sufficient to let me record my voice and save it as a file on my PC. But Windows Voice Recorder saves files in m4a format, and if you want to burn audio to an old-fashioned CD player you need a wav file instead.

The software that came to my rescue was Zamzar. It's a neat system that can convert any file to just about any other format you can think of. It'll convert document and spreadsheet files to and from PDF or e-book formats, for example. And it converts between dozens of audio formats too. Including between mp3, m4a, wav and others.

The nicest thing about Zamzar is that it's online, so you don't need to download anything. And it's completely free too. So add it to your bookmarks or favourites, for the next time you need to convert a file.  Read More
