No Sound on Interactive Keynote Widget?

OBJECTIVE: I am trying to imbed an interactive Keynote Widget into an iBook with short audio clips that play after transitions between slides. The Keynote presentation consists of 8 slides that generally consist of an image, a couple of buttons (shapes with associated links to specific slides), a text box or two, and some have inserted audio .m4a files (less than 5 seconds in length). The audio objects are set to 'start after transition'. The overall presentation is set as a 'Links only' presentation type.

PROBLEM: After testing succesfully in Keynote, I saved the presentation, dragged it into iBooks author, and previewed it in iBooks (running on OSX 10.9.2 Mavericks). The widget works splendidly... except the sound. Audio objects aren't activated by transitions. No sound at all out of the Keynote Widget.


WHAT I'VE TRIED: I have checked that sound is working right on my Mac. In fact, Audio widgets on the next page of the same iBook work fine. I changed the audio files in the keynote presentation with a different one that was already working in my iBook as an audio widget. I have tried putting the keynote presentation into a untouched standard Apple template. No sound at all from the Keynote Widget. I also looked for solutions in online help files, Apple's Developer Forums for iBooks Author, and here in this section of the Apple Support Communities. I only found two similar questions/problems neither with a posted resolution (https://discussions.apple.com/thread/5119988?answerId=22443281022#22443281022 and https://discussions.apple.com/thread/5160142).


TECH SPECS:


iBooks version 1.0.1

iBooks Author version 2.1.1

Keynote version 6.1

OSX version 10.9.2


Any ideas as to what I am doing wrong? Or is it an inherent limitation in the program? Any help will be greatly appreciated.

Mac mini (Mid 2011), OS X Mavericks (10.9.2)

You may be right, Macstier. Up till now I haven't seen anyone indicate they have ever gotten any sound to come out of a Keynote widget.


Thanks too for the suggestion about using a Quicktime movie. That could be a viable alternative for some. Unfotunately for me, I am trying to build an interactive multimedia quiz as mentioned on my previous posts. A video in a Media Widget won't let me do that since it is not interactive, and the Quiz Widgets don't suffice since they can't handle audio. I guess if Keynote is not an option, the only way to do it would be using HTML5. I have had success getting sound to work in an HTML5 widget. A Keynote presentation is much easier to put together though, and the Keynote widget is nicer since you don't have to go full screen if you don't want to.


Also, if that is the case, if Keynote will not take any audio what so ever into a keynote widget in iBooks Author, wouldn't you agree that the following documentation from Apple is at best very misleading, or perhaps completely inaccurate?


(iBooks Author: About the Keynote widget -http://support.apple.com/kb/HT5067).


Keynote files can contain media—such as images, movies, and audio—but don’t use a Keynote file just to add media to your book.

It doesn't make sense that Apple would say: 'Keynote files [in iBooks Author] can contain [...] audio', if Keynote does not take audio with it to iBooks. Either they are wrong, or there is something we don't understand about the process.


What do you think?

Kathy,


Sorry I took so long to reply to your last question with reference to converting m4a to m4p...

I'm just converting them by changing the file extension. Should I be doing something more complex?

I'm not sure what the answer is to the question. However I did find this information online (at http://www.aimersoft.com/itunes-drm/m4a-vs-m4p.html).

It is important to note that there is a vast difference between these two files. M4A files do not have Digital Rights Management (DRM) and the audio quality is different on these files.

Bitrate is the measurement that is used to measure the quality of audio files. Devices with a high bitrate have better digital audio quality as it means that more audio data can be encoded. Apple M4P files were sold with a 128 bit rate, which is much lower than what is required by M4A files with a 256 kbps speed.

It is possible to use any CD ripping program to encode songs that have higher bitrates. When listening to music through top of the range headphones and speakers it is easy to hear the difference between 128 and 256 kpbs. This is not necessarily the case with bottom of the range headphones or speakers. Most people will say that with the top of the range listening equipment, the difference with 256 kpbs is far better.

Digital Rights Management is included in these files to restrict users' ability to share the files. DRM was always sold on M4P files. In the case of Apple, it reduces the number of devices that can be used.

M4A & M4P Differences (M4A vs M4P) do include the fact that there are limits as to how many times a song can be burned onto a CD. This is highlighted by the fact that M4A files have no restrictions and they are free of DRM. You will note that you cannot convert DRM files to formats that do not incorporate DRM.

If this info is accurate it would seem that the difference between .m4a and .m4p is more than just the file name extension. I would guess that maybe you need an app that does audio converting. I believe you can find a free one in the Mac App Store.

Hi,

I hope you have sorted out your issues with key notes. I just wanted to let you know I finally managed to get my audio files accepted by the ibook submission process! This is what I had to do in the end:

Recorded podcast in garage band which resulted in m4a file. Sent this to itunes, created a duplicate new file of this and clicked save as AAC version, this made the sample rate 44,100. I then did cmd I and changed the file from m4a to m4p.

I think the problem with the m4p files that I had uploaded previously is they all had variable sample rates. Saving as AAC in itunes made all the sample rates the same.

This made ibooks submission happy and me very happy!


Hope this info is helpful to someone. Thanks for helping me.

All best

Kathy
