Audio

Why use audio?

Learning styles vary from person to person. Some people learn and retain information mainly through sight, some through activity, and still others through hearing. A good online course will incorporate elements of all three learning styles.

Audio is a great way to reach out to your students. Recording a short audio clip of yourself talking provides for personalization, immediacy and allows for the student to make a connection to you. You want them to know you are a real person and that the course isn't taught by a computer. It is also valuable so that students can hear the inflection in your voice and get a better sense of what ideas, concepts, or topics you are stressing.

Some subjects lend themselves to audio, while others lend themselves to visual mediums.


What to consider

Adding Files: Files can be added to the LearningStudio (college) shell either by selecting "Add a Link" then linking to the file from the visual editor or by embedding a player into the course. If you add a link, the students will select the link, then download the file and play it on their computer using their preferred player. If you embed a player in the course, then the students will need the software, such as flash, to play the file. While this is a "slicker" interface, a link should be provided to the students to download the appropriate software.

Recording files: While links to audio may readily be added to courses in the LearningStudio (eCollege) platform, you will be using third-party tools to develop your audio files. Help in the use of these third-party audio tools is provided by the companies producing the tools and not by the Pearson Help Desk.
Equipment and File Size

Equipment: Most computers today come equipped with all the necessary equipment to create sound files. If your computer does not have this equipment, you can purchase a multimedia sound kit, such as the Sound Blaster Card, from many of your local stores. You need:

  • A sound card with an analog-to-digital converter – if your computer already possesses a sound card (can you play sound through your speakers or headphones? Then you have a sound card!), it has this converter.
  • An audio application (program) that recognizes and allows you to save certain types of sound files.
  • A microphone.

The first step in making a recording is generally to plug a microphone into the sound input jack on your sound card; or, if using a USB-connected microphone, a USB port on your computer With your microphone, you can record your voice, or use it to capture your own sound effects.


Software

Some tools have free demonstration copies or are offered free of charge--see the sites listed below. Some tools are updated frequently requiring downloads to ensure the most recent version is in use. TCU eLearning and Pearson do not endorse or provide technical support for these products.

  • Audacity (Mac & PC)A very popular (and free!) digital audio recording and manipulation solution for Windows and Mac. For recordings that are more complex, with the ability to edit the audio, split tracks, combine tracks, etc, Audacity will be a great asset to you.
  • Sound Recorder - You can find this program in your Programs Folder--> Accessories--> Entertainment--> Sound Recorder . This is a bare basics sound recorder that comes with your PC.
  • Garage Band (Mac) - Apple bundled software that allows you to create your own audio recordings, enhanced podcasts (voice & images), and record instruments.

 


Recording Tips

  1. Purchase a good microphone. This can be done at your local electronics store (BestBuy, CompUSA, etc), and you can expect to spend $15 to over $100. A microphone with a USB connection will offer the best mix of simplicity and audio quality.
  2. Find a quiet place to record. Any sounds that are not your voice are considered noise. The hum of a refrigerator, traffic from a near-by street, or your dog panting… all of these will act to drown out the what you are trying to record.
  3. Test your equipment and adjust your levels before you begin. Your levels should be strong but not "live" in the red of the meters. If they jump into the red for a split second that is okay… so long as they are not there all the time.
  4. Trust your sound meter, not your speakers. Speakers can lie, because the volume can be pumped loud enough so it "appears" that the audio is strong. However, this volume adjustment has no effect on the sound you are recording because it is on the ouput, not the input.
  5. Once you begin recording, wait a couple seconds before you begin to talk. If you talk too soon, it may not record your first few words.
  6. Before you stop recording, pause and be silent for a second. This will ensure that you don't cut off your final word(s).
  7. If you have a lot of material to present, consider presenting it in smaller chunks. Listening to long presentations… especially while sitting at a computer… tends to become tedious. Chunking material into smaller presentations helps the student retain the information.

Why Audio and not Video?

With the ubiquity of webcams in our laptops and the ease of recording video now, video is often the easier choice. However, you need to consider that video requires more resources on the network. Some students, even in 2012 and beyond, still have dial-up. Audio files are easier to download on any connection, and you can record your audio without worrying about what you are wearing or if you fixed your hair. Audio files can simply be linked as a file within your course, or, if you are more daring, you can use our embed instructions to place a player within your course to play the audio directly in the content item.
