Explanation of how to introduce Voicethread gradually to a group of students, providing support to encourage students to leave comments with audio and/or video.
Practical ideas for adding a little stock music to e-learning. It's probably not a good idea to add it behind narration, but a little bit of music might be beneficial in some situations. It can reinforce or shape the emotional feel of a moment in learning.
The method of labeling and using "Export multiple" worked really well for creating audio for Captivate
Tips for streamlining the process of adding multiple audio files to Captivate
Free templates, sound effects, graphics, and more
Two IDs look at the use of audio narration--how much, quality of speakers, quality of equipment. Includes guidelines based on their survey of employees. I wish they had some more info about the survey they conducted though (i.e., how many responses they received, how many total employees at the company, etc.)

[How much?] We will use audio only when instructionally necessary.
-
[Control] We will make sure students have the ability to turn the sound on and off, and that they know how to do so.
-
[Who?] We will continue to use in-house talent, but other than credits at the end, we will not identify the narrator unless his or her name or title is pertinent for the instruction, e.g., having the Compliance Officer introduce a compliance course. This will prevent having to re-narrate when someone changes position or leaves the company. We may audition to get more suitable voices.
-
[Quality] We only need slightly a higher quality microphone along with a pop filter to raise our technical quality to the practical limit. We also identified a storage room that will double as our sound studio with the use of inexpensive draperies. This location should improve our ability to splice in updates without sounding noticeably different from the original.
-
We will continue to have learners evaluate the use and quality of our narration and make adjustments accordingly.
Here are the guidelines we have adopted as a result of this study:
-
-
Only 12% said they prefer professional voice talent. A full 85% said the voice only needs to sound good enough to get the point across without having to strain to understand it. Nearly 60% of our employees said “no preference” as long as the voice isn’t irritating to listen to. 40% prefer that the narrator be someone they recognize (i.e., a well-known manager, process owner, or SME). A surprising 9% said the narration could be computer-generated as long as it didn’t sound too robot-like.

Great summary of research points on our perceptions of media with implications for using media effectively for learning. For example, audio quality matters a lot, but video quality can be low and still effective. Large, wide screens are preferred over higher quality images on smaller screens.
-
35 psychological studies into the human reaction to media all point towards the simple proposition that people react towards media socially even though, at a conscious level, they believe it is not reasonable to do so. They can't help it. In short, people think that computers are people, which makes e-learning work.

As long as a media technology is consistent with social and physical rules, we will accept it. Read that last part again, 'as long as a media technology is consistent with social and physical rules'. If the media technology fails to conform to these human expectations - we will very much not accept it.
How to write scripts to be read aloud, primarily when providing scripts for professional voice talent. A little dated (talking about faxing scripts), but some good things to remember if someone else will read your script
Suggestions for writing how people talk and creating audio scripts that don't sound stiff and are clear

Results of an experiment on the encoding bitrate for Captivate. Mark Siegriest is trying to find the best audio settings to balance sound quality and file size.
The most surprising finding in this is that at the lowest bitrates, the file size actually went up, not down. 32kbps was the smallest file size in his sampling.
-
So basically from what I can see there is no point in ever going below 32kbps as you’re gaining filesize and losing quality.
