2.6. Creating a configuration file.
Run dict.exe program and in the opened window select tab "Setting up the voice
recorder", as shown in Fig. 3. This tab is used to create / read files
dict.ini
and it contains the
following parameters and options:
a)
Enable\disable voice activation (VOX).
When this mode is active, recorder starts
recording once the audio level of a sound signal exceeds a predetermined threshold. If the
audio level is below a predetermined threshold for 15 seconds, then the voice recorder stops
recording and enters the standby mode of the acoustic signal, without closing of the current
file. Sound recording fragments are consistently registered in the current file (up to 70 frag-
ments in one file). For each voice operated switching the tag indicating date and time of
voice operated activation (the beginning of a fragment) will be created in the file (see para-
graph
3
). Record fragments of voice operated switch will be separated in the file from each
other with either silence, or beep (item 2.6 (
b
)).
b) Beep between fragments
. After switching the voice activated mode on, the user can
choose a way of fragments separation in the current file. In case of setting a tag
"Beep be-
tween fragments",
all sound recording fragments in the current file will be divided by
beeps, or, otherwise by silence. Use of beeps between fragments allows the user to define au-
rally the beginning of a new fragment when listening files.
c) Sensitivity of voice recording switch
. The user can adjust a threshold of voice operated
switch by setting of value in the “
Sensitivity of VOX
” window. The higher the chosen sensi-
tivity, the quieter sounds will be recognized by recorder. The recommended sensitivity value
is
"average".
Under sound resolution of 20 bits sensitivity of VOX is a fixed value and is
not adjustable.
d) To switch on/off the automatic adjustment of record level.
After activation of this func-
tion, loud sounds will be weakened, and quiet, on the contrary – amplified. That will allow
aligning the sound level automatically. This function isn't available (is not required) at sound
resolution of 20 bits.
e) To set the fixed strengthening of record level
. If the user or the program have turned
sound level automatic adjustment off, then it is necessary to set record level amplification
from the available row. The recommended values are 0 dB, +6 dB and +12 dB. This function
isn't available (is not required) at resolution of a sound of 20 bits.
f) To set the written-down files size.
In this window the user has to choose the files size
recorded to the memory card from the following row: 50 MB, 100 MB, 250 MB, 500 MB,
1000 MB, 1800 MB. The less the files size, the less time is required for their opening, but the
more short-term pauses are in a sound recording when opening the new file.
