Windows & Mac
When it comes to audio, our standards should be high.
Many people use their phones as the primary source of music. But they also use their ears as the primary instrument for listening to music.
I’ve worked for 9 years as a sound engineer in a major dubbing studio in Portugal. I trained my years to find the most subtle details in any audio coming from my speakers.
With this in mind, I was able to find some really neat audio converters on the web. There are tons of online audio converters, but I’m here to share the best ones with you.
Here’s a list of the best audio converter software:
- Audials Music
- WonderFox Free HD Video Converter Factory
- Stellar Audio Converter
- Xilisoft Audio Converter
- MediaHuman Audio Converter
- Switch Audio Converter
- Freemake Audio Converter
- Hamster Free Audio Converter
- VSDC Free Audio Converter
- Helium Converter
Audials Music converter is on top of this list because of its admirable features.
Besides being a good audio converter software, it lets you download and convert music directly from Spotify and other streaming services.
Not all audio converters record audio, songs, audiobooks, albums, and playlists from streaming services. This makes Audials Music an excellent choice for those who want to quickly (and legally) convert audio from their favorite streaming services.
Unfortunately, there’s no Mac version, as it’s only available for Windows.
- Labels and adds metadata to tracks during conversion.
- Records songs 15x faster than regular playback.
- Convert audiobooks at 10x speed.
- Converts 41 audio files to 10 audio file formats.
Audials Music is not the cheapest audio converter, as they charge a one-time fee of $38.37. Plus, they even charge for upgrades.
But I have a special deal for my readers: you can get Audials Music for $19.90 through this link.
However, if you’re someone who’s constantly in need of converting lots of files and especially if you need batch conversion to speed your workflow, it’s worth the investment. Also, there can be a bit of a learning curve as features abound.
