FFmpeg is an open-source file converter that combines the work of developers from around the world and hones it into maybe the most robust conversion tool you can find on the internet. Understandably then, it can of course be used as an audio file converter – free to use as well if you understand how it operates.
But that’s the tricky part, specifically the learning curve. This tool was created by computer developers who have a good understanding of codebases, audio codecs, containers, and the like. If you’ve never heard of Github, you should probably look elsewhere for your audio-converting needs.
Pros:
Customizable if you’re a developer
Runs on any OS
Huge range of file inputs and outputs
Cons:
Not friendly for non tech-savvy people
OS: Mac OS X 10.6 or later, Windows 2003 or later
Best for: Splitting audio files automatically (via .CUE files)
Input: AAC, ALAC, APE, WMA, WAV, MP3, M4A, OGG, FLAC, WavPack

PCWorld review: “Depending on the format that was used to create the video (I’m looking at you, MKV), it might not play properly. You need a converter, a utility that changes a video from one format to another. And I’ve yet to find one that’s easier to use (or has a better name) than Hamster Free Video Converter.”
Hamster Free Audio Converter is another tool at your disposal when converting audio. With a gentle learning curve and usability on most modern electronic devices, this software can help you convert audio files without overwhelming you with tons of intricate (and often unnecessary) features.
Pros:
Easy to use
Compatible with 200+ devices

Lacks in settings for adjusting audio quality

We hope our run-through of 15 top online audio converters helped you determine your top option(s) to convert audio on your computer. Whether you’re looking for the best free music converter for converting to MP3 or need something with more features, there’s definitely an option online to better meet your needs.
Still unsure which converter to use? Here’s a quick look at the most notable things to pay attention to when picking out your audio converter:
Interface: make sure that whatever audio-conversion tool you end up downloading is easy enough for you personally to use. Most developers try to make software that suits their own audience, and if their audience is a bunch of computer developers (and you’re not) then you’ll struggle to use their tool even if you like what their tool can do.
Features: what do you specifically need from your audio converter? If you’re just looking to convert a few old audio files to MP3, then you don’t need a tool that helps you adjust file size and quality, do batch conversions, or help you organize songs into album folders.
Supported file formats: while it’s a good idea to choose the audio conversion software with the biggest range of input and output formats, you ultimately only need a converter that will input your files and output the new audio codec you want. If you can’t find input and outputs on the developer’s website, Wikipedia can usually help.
Reviews and star ratings: want to avoid a headache using software that’s buggy or lacks good customer support? See what users are already saying about the audio converter you’ve got your eye on.
Customer support: developers who keep their pages updated and have clear avenues to reach their customer service team can be the difference-maker when choosing between audio converters. Investigate customer support options before finalizing the software you choose.
