Chapter 4
Overview
Gnome-2M c
provides a lot of capabilities for easy and comfortable speech recording:
•The data are recorded by built-in or external microphones to removable Compact Flash I mem-
ory cards.
•The recording may be started and stopped either manually or automatically at a specified time.
It is possible to schedule recording sessions using up to 5 timers simultaneously. Once the
timer’s priority mode option has been enabled, the recording cannot be stopped manually.
•Switching compression on/off.
•Sampling rate can be changed to better suit the recording conditions.
•Voice Activation mode (VA ) allows the recording to start only if the gain level is higher than
a certain threshold value (Start Threshold ).
•Recording in loop mode (Loop) allows continuous recording into limited disk space. Once the
limit of the disk space has been reached, previously recorded data will be erased and replaced
with new data.
•Noise-cancellation features are now available during recording playback (for sound recordings
made at a sampling rate of 8, 10 and 16 kHz). Gnome-2M c
includes broadband and composite
(i.e. broadband & inverse) filters. Suppression depth for both filters is adjustable within the
0-30 dB range with a 6 dB step.
•Playback speed control. This mode allows acceleration and deceleration of playback tempo
up to 2,5 times. Available for sound data recorded at 8, 10 and 16 kHz.
•LCD may be automatically switched off during recording. This mode perfectly protects the
recording from possible detection.
•List of all the existing recordings can always be viewed.
•Loop playback of any selected recording or its fragment is available.
•Gnome-2M c
can be used as a standard Sound Blaster. This allows playback of sound files
from a PC connected to the voice-recorder.
•Quick search for voice signal in long sound recordings.
•PIN-code and protect key changing possibility.
