An audio file converter is one kind of file converter that (surprise!) 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.
1. Free Studio
Free Studio is actually a group of several programs. Just click Convert from the main menu, and then choose the Free Audio Converter option to open the audio converter tool.
Free Studio is very easy to use and lets you choose an output quality, fill out audio tags, automatically shut down the computer after converting files, and import files from the Windows right-click context menu.
Input Formats: AAC, AC3, AIF, AIFF, ALAC, AMR, APE, ASF, AU, CAF, CUE, FLAC, M4B, MKA, MP2, MP3, MPC, OGG, RA, RAM, RM, RMM, RMVB, SHN, SPX, TTA, WAV, and WMA
Output Formats: AAC, ALAC, AMR, FLAC, OGG, M4B, M4R, MP3, WAV, and WMA
Free Studio also lets you extract audio from YouTube, audio CDs, and most video formats.
Free Studio works with Windows 10, 8, 7, Vista, and XP.
Freemake Audio Converter supports several common audio formats and is extremely easy to use.
Input Formats: AAC, AMR, AC3, FLAC, M4A, M4R, MP3, OGG, WAV, and WMA
Output Formats: AAC, FLAC, M4A, MP3, OGG, WAV, and WMA
In addition to converting single audio files into other formats in bulk, you can join multiple files into one larger audio files with Freemake Audio Converter.
You can also adjust the output quality before converting files.
Note: The installer for Freemake Audio Converter will attempt to install other programs that are unrelated to the converter, so be sure to uncheck those options before finishing setup if you don’t want them added to your computer.
Zamzar is another online audio converter service that supports most common music and audio formats.
Input Formats: 3GA, AAC, AC3, AIFF, AIFC, CAF, FLAC, M4A, M4B, M4R, MIDI, MP3, OGA, OGG, RA, RAM, WAV, and WMA
Output Formats: AAC, AC3, FLAC, M4A, M4R, MP3, OGG, WAV, and WMA
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.
If you’re looking for a simple program that works without the advanced options and confusing interfaces that some of these audio converter tools have, you’ll definitely like MediaHuman Audio Converter.
Just drag and drop the audio files you need converted directly into the program, choose an output format, and then start the conversion.
Input Formats: AAC, AC3, AIF, AIFF, ALAW, AMR, APE, AU, CAF, DTS, FLAC, M4A, M4B, M4R, MP2, MP3, MPC, OGG, OPUS, RA, SHN, TTA, WAV, WMA, and WV
Output Formats: AAC, AC3, AIFF, ALAC, FLAC, M4R, MP3, OGG, WAV, and WMA
If you do want more advanced options, MediaHuman Audio Converter does let you customize things like the default output folder, whether you want to automatically add the converted songs to iTunes, and if you want to search for covert art from online, among other options.
Fortunately, these settings are hidden away and are completely unobtrusive unless you want to use them.
The following operating systems are supported: Windows 10, Windows 8, Windows 7, Windows Vista, Windows XP, Windows Server 2003, and Mac OS X 10.5 and newer.
VSDC Free Audio Converter has a tabbed interface that’s uncomplicated to understand and isn’t cluttered with unnecessary buttons.
Just load up the audio files you want to convert, or enter the URL for an online file, choose the Formats tab to select an output format, and click Start conversion to convert the files.
There’s also a tag editor for modifying a track’s title, author, album, genre, etc., as well as a built-in player for listening to songs before you convert them.
Input Formats: AAC, AFC, AIF, AIFC, AIFF, AMR, ASF, M2A, M3U, M4A, MP2, MP3, MPC, OGG, OMA, RA, RM, VOC, WAV, WMA, and WV
Output Formats: AAC, AIFF, AMR, AU, M4A, MP3, OGG, WAV, and WMA
Note: The installer will try to add unnecessary programs and tools to your computer if you let it. Be sure to watch for these and disable them if you wish.
If you need to, you can choose an alternative output quality, frequency, and bitrate from the advanced options.
Overall, VSDC Free Audio Converter is just as quick as most of the other tools in this list, and is great for converting your files to a common format.
VSDC Free Audio Converter is said to be compatible with all Windows operating systems. I used the program in Windows 10 and it worked just as advertised.
