M4B Audio Format

M4B Converter

An M4B file is also known as an MPEG-4 Audiobook file and was developed by Apple. Given its name it’s perhaps not surprising that an M4B file is commonly used for audio books. They’re used by Apple Books – specifically the audio part – and the file itself is designed to be efficient as it has been compressed using AAC encoding which means that they don’t consume much in the way of storage meaning they’re ideal for devices such as iPhones and iPads. They’re similar to an M4R file in that M4B can only be played on authorised computers to prevent piracy so often when trying to play the file users can run into problems trying to get them to play if they’ve been forwarded the file on. M4B files can be opened by Apple devices and on iTunes on either MacOS or Windows.

M4A Audio Format

M4A Converter

An M4A file format is also called an MPEG-4 audio file, and is an audio file saved in the MPEG-4 standard. It was developed by Apple, largely as a result of the popularity of the MP3 file. An M4A file is the go-to audio format for compressed audio, due to the creation and popularity of iTunes.

M4A files tend to be encoded using an AAC codec and are small in size because they have been compressed - often providing a smaller file-size footprint than an MP3 file format, while mirroring, if not improving, the quality of an MP3 file. As more and more music was consumed on the go via devices such as iPods and smartphones, the need for small file sizes became greater, which is why an M4A file has grown in popularity and importance.

One downside of an M4A file, especially when compared to an MP3 format, is that it can only be opened by iTunes or Windows Media Player version 12 and later. By comparison, an MP3 file is universally supported.
