by Tim Fisher is used to convert one type of audio file (like an MP3, WAV, WMA, etc.) into another type of audio file. If you're unable to play or edit a certain audio file the way you wanted because the format isn't supported by the software you're using, one of these free audio converter software programs or online tools can help.
Audio file converter tools are also helpful if your favorite music app on your phone or tablet doesn't support the format that a new song you downloaded is in. An audio converter can convert that obscure format into a format that your app supports.
Below is a ranked list of the best free audio converter software programs and online converter services available today:
Important: Every audio converter program below is freeware. I haven't listed any shareware or trialware audio converters. Please let me know if one of them has started charging and I'll remove it.

FileZigZag Review and Link

Zamzar Review and Link
The biggest disadvantage with Zamzar is their 50 MB limit for source files. While many audio files are smaller than this, some low compression formats can exceed this small limit.
I also found Zamzar's conversion time slow when compared to other online audio converter services.
Zamzar can be used with pretty much any modern web browser on any OS, such as Windows, Mac, and Linux. More »
