|Audio Testing and Setup|
Experience shows that audio recording requires careful attention to the room, microphone, and computer in use. Best results occur by running audio sound checks in advance of a session using all the same equipment and in the room where you will be recording with the Lecture123 Presenter. You will best served by performing one or two very fast audio tests along with some possible configuration tweaks -- this can usually be accomplished in less than a minute.
Here are some issues that you should consider when recording:
Shure Presenter PG14/PG185 Wireless Lavalier System UHF mic kit (note: these kits come in varying frequencies; when ordering more than one kit, buy each one with a different frequency to avoid contention).
We've also had reports of good success of this Audio Technica kit:
Audio Technica ATW701/L 700 Series - 8 Channel UHF, Lavalier Microphone; Transmitter: ATW-T701; Reciever: ATW-R700. Please shop for a good price on the web, e.g. beachaudio.com.
Here's a sequence of steps for performing a quick recording test with your computer audio microphone and speakers before using the Lecture123 Presenter to record a session.
Once the audio levels work well with the Sound Recorder you are ready to test with the Lecture123 Presenter. Simply launch the Presenter program and start recording a session (either blank slides or PowerPoint is fine). As you speak you should see a volume meter near the top left of the Presenter window. As long as the meter is showing movement, the audio is likely fine (note: every computer audio levels seem to vary). Stop the Presenter session and play it back in the Lecture123 Player. You can play back the local unpublished session or publish the test session and play it back from the Lecture123 Play web page in your browser.
