From the Breeze menu, select Preferences.
3.
Select the Quality tab.
4.
In the Audio Options dialog box, set the following options:
Input Source
specifies the type of recording device you are using to create audio. Select
Microphone if you are using a microphone, or select Line in if you are using a different type of
recording device.
Audio Quality specifies a quality level for the audio. Select an option in the pop-up menu.
Remember that a higher quality level results in a larger audio file size.
Calibrate Input displays the Calibrate Microphone dialog box. It’s important to calibrate your
recording device for optimal sound quality.

Changing the audio input source
If you are recording audio for a presentation, you can either use a microphone or the line-in
option that is usually included with an external audio device such as a tape deck or stereo
amplifier.
To change the audio input source:
1.
In PowerPoint, open a presentation (PPT file).
2.
From the Breeze menu, select Preferences.
3.
Select the Audio Source tab.
4.
In the Audio Input Source area, select either Microphone or Line in.

(Optional) Select the Always Prompt to Set Microphone Level Before Recording option if you
want to calibrate the microphone before each recording session. This is useful if you use
different microphones or if you record in different environments (i.e., a quiet room versus an
area with background noise).

Calibrating microphones for recording
If you are recording audio for a presentation, you must set the microphone or recording device to
the correct recording level. This process is called
calibrating the recording device . Breeze Presenter
can detect optimal microphone and recording sensitivity levels automatically.
Note: Breeze Presenter must be able to detect a recording device before trying to calibrate. Check
that a microphone or recording device (such as a tape deck or stereo amplifier) that uses the line-in
option is connected to your computer properly and is turned on before calibrating.
