Introduction
The Call Recorder Octo | Quarto is a digital audio recorder which can
simultaneously record from eight/four analogue telephone lines or
eight/four mono audio-sources. The Octo |Quarto is designed for
continuous unattended recording. Recording is started and stopped
automatically for each individual call. The quality of recordings is
ensured by the Automatic Gain Control, which evens the recording levels
of the local and remote voices. When recording from other audio
sources, voice activated recording starts and stops recording
automatically. The Octo | Quarto also has connections for a start/stop
switch for every channel.
Internal Drive
The Octo | Quarto has an internal Drive, a network interface and an
optional CD writer. All recordings are stored digitally on the internal
Drive. The large storage capacity of the Drive ensures the Call Recorder's
ability of long term unattended recording. Other advantages are that
recordings are randomly accessible and that there is no risk of erasing
existing recordings by new recordings. The Octo | Quarto issues a
warning when the Drive is getting full. If the warning is ignored the
oldest recordings will be overwritten by the newest. Stored recordings
can be archived using the optional Call Recorder Archiving System
software. It is also possible to copy recordings from the Drive to a CD if
your Octo | Quarto is equipped with the CD recorder. Copying recordings
to a recordable-CD can be done in different ways for different purposes.
It is possible to copy single recordings, copy a selection of recordings or
continuous copy new recordings automatically. Recordings on CD can
be viewed and played-back with the Call Recorder Quick CD Access
System software that comes with the Octo | Quarto.
Compression
The digital format of the recordings is determined by the use of speech
compression. The Octo | Quarto compresses recordings default according
to the G.723 High Rate format. G.723 High Rate compression provides a
good balance between audio quality and recording size and is
compatible with most Windows versions. Compressed recordings take up
1/10th of the size of uncompressed recordings. Therefore the
compression has a profound effect on the storage capacity of the Call
Recorder in terms of recording size.
