Audio content in an Epub

Post by Val »

Hello,

I would like to create an Epub with audio content for/with my pupils.
I tried to make a link with a ".wav" but once downloaded in an Epub reader, there is no sound.
Is it possible to do that with Atlantis or any other Epub creator ?
And how ?

Thanks for replying,

Hi Val,
As things stand, only the Ipad and iPhone support embedded audio or video (mp3/mp4). But it seems it isn’t such a great support as that. One of our Atlantis users tried to embed audio in his EPUB files. His iPad plays the embedded audio only for the first 4 pages. The audio embedded in the next pages is never played at all. He hasn’t been able to solve that mystery.

This said, the EPUB 3 standard supports embedded audio or video. The problem is that very few, if any eReaders currently support the EPUB 3 standard. Even the Ipad and iPhone have no support for the EPUB 3 standard. They support embedded audio or video because they have a special engine to do so.

This is why Atlantis currently does not support the EPUB 3 standard. It would be rather pointless.

Now if you want to try your luck embedding audio or video code in the EPUB files created by Atlantis, you’ll have to insert the following codes into your files manually. You can do it with the free Tweak_EPUB utility available from Introduction to the tweak_epub utility
You’ll get a French version of this same utility if you download Retouche EPUB. You’ll also get detailed explanations in French on the use of this utility in Retoucher un fichier EPUB.rtf.

Here is the EPUB code to use:

Code: Select all

<audio controls="controls" preload="auto" height="385" width="480" src="../Misc/example.mp3">&#40;Cannot read example.mp3. This eReader does not support embedded audio&#41;</audio>

Code: Select all

<video controls="controls" preload="auto" height="385" width="480" src="../Misc/example.mp4">&#40;Cannot read example.mp4. This eReader does not support embedded video&#41;</video>
Simply insert the above code lines wherever you want the corresponding audio or video to become audible/visible.

Good luck!

HTH.
Cheers,
Robert
