Recording audio
In addition to adding existing audio files, you can also record your own audio files to use in Presenter presentations.
Recorded files are saved in mp3 format. Follow these tips to ensure that you are recording the highest quality audio
possible.
Setting up audio equipment
When you have acquired the necessary audio recording equipment, you must set it up properly. If you are just using
a microphone, plug the microphone into the computer and start recording. Alternatively, you can plug the micro-
phone into a mixer or stand-alone preamplifier, and then plug the output of that device into your computer sound
card’s “line in.” Plug the headphones into your computer. Then, set the volume on the mixer or preamplifier. Begin
speaking to test the volume levels, and carefully raise the volume until it shows just under zero. (Using a preamplifier
and line-in socket is optional.)
Setting sound card options
You can open the software application that controls the sound card. (In most Windows operating systems, you can
find sound settings by clicking Start in the lower-left corner and selecting Settings
> Control Panel > Sounds.) When
you select the recording source (line in), you can adjust the volume to 100%. If you are using a mixer or stand-alone
preamplifier, the actual recording level can be controlled from there.
Changing audio recording settings
After starting your audio recording software, you can change the settings as necessary. Mixers and preamplifiers
don’t have sound-level controls, so you rely on the meters when recording. While recording, ensure that you don’t
exceed zero on the meters, or the sound will be distorted.
Placing the microphone
Positioning your microphone correctly can make a big difference in the finished audio file. First, get as close as
possible to the microphone (within 4–6 inches) so that you avoid recording any other nearby sounds. Don’t speak
down to the microphone; instead, position it above your nose and pointed down at your mouth. Finally, position
the microphone slightly to the side of your mouth, to help soften the sound of the letters
s and p .
