I'm, the author of the app, listen to audiobooks all the time. Therefore, I did my best to make MP3 Audiobook Player a tool that has everything necessary to make this process intuitive and convenient. • Plays audiobooks in MP3, MP4, OPUS, OGG, FLAC, AWB, M4B, M4A formats (without DRM protection). • Adjustable playback quality (0.5x to 5.0x). • Boost sound ( for audiobooks with low volume ) • The book cover is loaded from an image file in the book’s folder or from an embedded image from an audio file. • Automatically saves the current playback position for all audiobooks. • Supports CarPlay and integrations with over 50 other car models from Ford, GM, Mazda, BMW, Jaguar, Landrover and many more • Jump to any file (can be enabled in settings). • Supports standard headphone controls. • Supports Apple Watch. • Playback control from the Control Center and Block screen. • A sleep timer with adjustable sleep periods or sleep after the end of the current chapter. • Possibility to add/remove books through iTunes and from the computer via Wi-Fi • Support WebDav for adding audiobooks directly from Explorer on PC or from Finder on MacOS If you enjoy MP3 Audiobook Player, we would be glad if you consider writing a review.
