Readers ask: What Type Of Format Is Audio Books On?

11 Common Audiobook Formats You Must Know

Audio files come in all shapes and sizes, but the most common audiobook formats can be divided into two groups: those that you should care about and those that you can ignore.

1. Lossy Compressed Audio Formats

Lossy compression is a type of compression that loses data during the compression process, which means sacrificing quality and fidelity for file size in the case of audio. The good news is that you won’t be able to tell the difference in most cases.


Audible created the AAX file format, which is DRM-encoded and can only be played on Audible software. However, with the help of Audible Converter, you can convert AAX to MP3 and play the MP3 files on your favorite audio players or other third-party music apps.


Both formats include metadata such as chapter markers, images, and hyperlinks, but only the latter allows “bookmarks,” whereas the former does not.


AAC is the standard audio compression method used by YouTube, Android, iOS, iTunes, later Nintendo portables, and later PlayStations. The compression algorithm used by AAC is much more advanced and technical than MP3, and it is widely used today.

Ogg (.ogg)

Vorbis was first released in 2000 and quickly gained popularity due to its open source nature. Because MP3 and AAC have such strong footholds, OGG has had a difficult time breaking into the spotlight; for the time being, it’s primarily used by open source zealots.


WMA was created to address some of the flaws in the MP3 compression method, and it is superior to MP3 in terms of objective quality. However, few devices and platforms support WMA, and it offers no real advantages over AAC or OGG.

2. Lossless Compressed Audio Formats

Lossy compression allows files to be 2x to 5x larger, while lossless compression reduces file size without sacrificing quality. Lossless compression is much more difficult to achieve, but there are a few good formats for it.

FLAC (.flac)

FLAC is the most popular alternative to MP3 for CD audio, and it can compress a source file by up to 60% without losing any data. FLAC is supported by most major programs and devices, and it is free to play on any PC or Mac.

ALAC (.alac)

While ALAC is good, it’s slightly less efficient than FLAC when it comes to compression, and Apple users don’t have a choice between the two because they’re both supported by iTunes and iOS.

WMA (.wma)

WMA Lossless is the worst in terms of compression efficiency when compared to FLAC and ALAC, and it’s a proprietary format, so it’s no good for open source software fans. If you want lossless audio across multiple devices, stick with FLAC.
