18.5.1 Understanding Resolution, Peak Overload, and Range
About Resolution Values
Sound recordings are saved with 16-bit resolution which provides a
measurement range of about 90 dB. This means that the 831C is capable of
recording sound signals with amplitudes no more than 90 dB below the level
at which the selected range will overload.
Adjusting Peak Overload
During calibration, the 831C automatically calculates the peak overload
based on the current microphone type. To ensure the calibration will be
accurate, do the following:

Step 5
Verify or edit the selection for
Normal
or
High Range
. This results
in different values for upper and lower limits for any given microphone.
We recommend using the
Normal
range for sound recordings unless you
anticipate that recorded sounds will exceed 110dBA. In that case, choose
High
range.
18.5.2 Choosing a File Format for Sound Records
Step 1
To choose compressed or uncompressed sound records on the 831C, go to
Tools

Setup Manager
Sound tab
.
Sound recordings are saved in WAV format (uncompressed) unless you select
the

checkbox. The compression setting saves sound records in
OGG format. This compressed format is most portable—easily shared over
email and text or as an alert notification.
