The third step asks you to adjust the gain (or recording volume) of the microphone.
There’s a graphic display of the sound that’s currently being “heard” by the computer.
You’ll want to position the microphone and speak as you would when performing a
lesson. The object is to set the gain as high as possible without “clipping” the audio.
Clipping will create distortion in the audio. You will see the graphic display turn red
when clipping occurs. When you see clipping, adjust the gain lower and speak again.
When you’ve discovered an optimal gain setting, click Next to continue.
The final step allows you to perform an actual recording test. Click the Record button
to begin. Speak for several seconds, and then click the Stop button. Click the Play
button to hear what you’ve recorded. If you need to return to previous steps to make
corrections, you may do so as this time by clicking the Back button. If you are
satisfied with the sound, click Finish and your settings will be saved.
It is recommended that you check the box to Automatically terminate a lesson if
audio is not detected in order to avoid spending several minutes creating a lesson
only to learn that the audio has not been recorded due to a missing or switched-off
microphone.
Broadband options
A “broadband lesson” is one designed to be viewed by students with high-speed
Internet connections, such as cable modems and DSL. When the V1 creates a
broadband lesson, it is created with multiple-bit-rate streams, meaning that is can also
be viewed on a low-speed connection. However, the size of the files that you as an
instructor will be uploading to the Academy will increase by a factor of about 4. If you
are using a very slow and/or unreliable connected, you may not wish to create
broadband lessons.
