.WAV vs .OGG: Choosing a Format for your Application
Sound recordings are saved in .WAV format (uncompressed) unless you select the
Compression
checkbox. The compression setting saves sound records in .OGG format. The
.OGG file is more portable, and easily shared over email, and text, or as an alert
notification.
TAKE NOTE
When you choose .OGG format, verify that the 831C Data Storage setting is
USB
.
To access the Data Storage setting, press Tools


System Properties , and
press the
right softkey
(

) to open the Preferences tab.
While a .WAV file requires much more space, this format preserves frequency detail best. If
you plan to examine octave bands or specific frequencies of a sound recording, we
recommend using the .WAV format.
The following table describes the approximate file size for a 60-second sound recording in
each format. The .WAV file sizes in Table 19.2 are accurate to the nearest 50 kB. The .OGG
file sizes are approximations since every compressed file is unique.
Event sound recordings are available to play back directly from the 831C or in G4.
