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.
