Ranos settings
Settings are stored locally, but are
also synchronized with a database.
This is done in order to ensure the
settings are safe, even if a firmware
update fails. When a Ranos dB has
been unregistered from an account,
the default settings will be syn
chronized from the database at the
first following time the Connect App
checks for settings.
One part of the settings that
runs in the background is the FIR
(Finite Impulse Response) micro
phone correction filtering. A FIR
microphone correction filter can be
uploaded by Dutch Sensor Systems.
This filter is used to linearize the
frequency response of a micro
phone. The Ranos dB 1 makes use
of this filter, the dB 2 does not.
Firmware update
After connecting the Connect App to
the Ranos dB, the Connect App will
first check if there are any firmware
updates available. If a firmware up
date is available and critical, a popup
will show up. You cannot continue
further any in the app before install
ing the firmware update. If an update
is not critical it will become available
for installation from the “ranos info”
page. After a firmware update has
finished, the latest stored settings
will be restored.
