How the Integration of Audio with Text Enhances Learning.
Effectiveness of Audio in the E-learning Environment.
Audacity
A free program for recording and editing sound.
This program can be used for making ringtones, removing vocals, mixing, creating podcasts and transferring tapes and records to computer.
Allows educators to record a lecture for learners to review on their own to help with retaining new information.
The effectiveness of audio component of narration or music gains learner’s interest, when text alone would be considered boring (Articulate Network.com, 2012).
The Levelator
Software that will adjust the speaker’s audio level within a podcast or other audio file.
Software is mainly used for lectures, interviews, speeches, conferences, meetings, radio and TV programs. Its main use is to make audio files clear for projects.
Allows educators to alter the tone of the recording to provide audio that is appropriate for the learning environment. Therefore, reduces extraneous audio.
Combining the components of a compressor, normalizer, and limiter is effective with presentations that have multiple presenters. Learners are able to focus on learning course concepts by being able to clearly hear presenters. Learners will not having to strain to hear soft-spoken presenters nor cover their ears due to the loudness of other presenters (The Conversations Network, 2012).
Aviary Myna
Online audio editor that will remix music or audio clips by adding fade-ins and fade-outs, audio delays, loops, and other effects.
Aviray Myna is used to create and edit multi audio recordings type using Flash. Great source to help a storyboard or presentation to have quality sound.
Provides editing options that can enhance an instructional method and keep leaners engaged within the learning environment. Applies multimedia principles. (Clark & Mayer, 2011)
The effectiveness in e-learning allows learners to follow the transition of a presentation, linking one concept to another concept so the learner gains a full perspective of the material as it relates to the added audio and sound components (Aviary, 2012).
Narration/ Voiceover
Brief, clear, and effective audio used to guide learners through a lesson.
This is used for any type of presentation. It may be spoken by someone who is elsewhere in the production. For example, an instructor teaches a lesson or use step by step instructions with a voiceover following a presentation.
Applies contiguity principle and modality principlewithin the learning environment which allows the learner to fully comprehend the information simultaneously with audio, visuals, and lectures. (Clark & Mayer, 2011)
Narration and voiceover are effective in aiding learners in following learning patterns or tutorials as an educator introduces material in a segmented, pre-training strategy (Lindsey Abbott, 2012).
Podcasts
An electronic media file streamed online to a computer or mobile device.
A Podcast can be used by an educator to record lectures or difficult lessons. Podcast can even be used to record class discussions for learners who may be attending online.
Provides live or recorded audio that learners can review to gain information for further understanding of course’s content through convenient or mobile devices.
The Podcasts’ effectiveness in e-learning aids auditory learners as well as learners who are striving to learn foreign languages (Strategic Technology Solutions, 2012).
ProductionSync
Automatic sync technology. Software used for accurate lip synchronization for off-line production.
ProductionSync is used to align and synchronize an animated character’s lip movements, facial expressions, and gestures to its voice track.
Applies contiguity principle where narration is synchronized to the accurate lip movement of the animated pedagogical agent. Therefore, reduces extraneous processing.
Reduces the overloading of essential processing by narrating complex or lengthy material. (Clark and Mayer, 2011)
InstantSync
Automatic sync technology. Allows real time lip synchronization.
InstantSync is used to synchronize live animation or communication application. The animated character’s lip movements are automatically synced to its voice track for streaming audio application.
Applies contiguity principle where accurate mouth positioning of the streamed animated character plays at the same time the voice is played. Thus, reduces extraneous processing.
Streamed character agent provides real-time content, and allows for interaction between the agent and learner.
