Following is a video illustration (memoir of my dear Mum) of what can be done using Apple’s AAC (M4A, M4B) format – publishable via iTunes Connect. This extended audio book format allows the integration of audio and timed image display. Great for authors who make extensive use of tables, figures, photographs or other graphics in paperbacks and eBooks. We’ve even used it for a running table of contents to make audio book navigation easier on your mobile phone.
