Most popular audio formats

The one audio format that is widely used, and we are all familiar with, is MP3. However, there are many more audio formats in use with advanced compression techniques, and as a result, better ratio of sound quality and file size.

One of the MP3 format’s successor is AAC that is also widely used (Android, iOS, YouTube, etc.). But even AAC still hasn’t replaced MP3 as a number one supported audio format in use.

Not many audio formats are universally compatible with most devices like MP3, but these are more efficient regarding audio quality and file size. Such audio formats are OGG Vorbis and WMA.

There are a lot more audio formats in use that are not supported on many platforms. Even though they have advanced compression, they are still to find their place among the best audio formats. The most popular audio formats that our users use are listed below.

Supported conversions of audio files

Possible audio format conversions include conversions between all supported audio formats. However, for an audio format with lossy compression, it is not technically correct to convert to audio format with lossless compression and uncompressed file format.

For example, you can convert almost every audio format file to MP3, but you can’t convert MP3 to some of the uncompressed audio formats, and gain a better quality of audio, with any converter.

With this converter, you can also archive any audio format file. Technically, that means that as a result of this conversion, you get achieved audio file.

Which audio file format is the best for you?

If you purchase music from iTunes Store, your files will be in AAC format. Audio files on Amazon will mostly come in MP3 format, while on Spotify, for premium users, you’ll have files in Ogg Vorbis format.

Depending on your needs and devices you use to reproduce music, audiobooks, or any audio file, you’ll have to convert your audio files accordingly.

If you don’t want to compromise on audio quality, then you should choose formats with lossless compression such as FLAC, WV, M4A, SHN, etc. or uncompressed audio formats such as WAV, AIFF, AU, etc. However, files in these formats take a lot of storage space. Specifically, lossless formats are two to five times larger than lossy formats.

On the other hand, there are audio formats with lossy compression that have the slightly degraded quality of audio, but considerably smaller file size. If you are no bothered about the almost unnoticeable difference in sound reproduction, but you need to save storage space, you should choose lossy formats. The most known such formats are AAC, MP3, Vorbis, WMA, ATRAC, OPUS, etc.

The most important thing about audio formats is whether they are compatible with the device you want to open them on. Be sure to check out first, can your files be reproduced on your device, before transferring them, and when necessary, convert them to correspondent audio format.

For the universal compatibility, convert your files to MP3 format. That way, you can be sure that you’ll be able to reproduce your audio files on most devices you have.
