Overlook
SoundProcessor is free software intended for:
• Processing of recordings to improve their
intelligibility;
• Significantly simplifying manual transfer of
recordings to text;
• Providing automatic transfer of recordings to
text using Google technology.
Despite
its
professional
characteristics,
SoundProcessor is easily accessible in use, even
by an amateur. SoundProcessor is a freeware.
SoundProcessor has been optimized to process
records from the Edic-mini recorders and has a
unique option to process up to 8 audio channels.
SoundProcessor features the most essential
functions which are easy to understand and apply.
Due to the transparent arrangement of menu and
operating area located in one window, you don't
have to spend time searching.
Attention! The audio files on your voice
recorder edited by the SoundProcessor program
lose markers. If you want to use the recording in
court, always save unedited copy of recording.
Let us dwell on the key features:
Convenient segmentation of recording
and saving as new files
Just select the desired part of the recording →
pop-up window appears → select «Open in new
form.»
Commenting records
In the pop-up window, you can click «Add a
comment» → window for writing text comment
to the selected part of record opens. That can
significantly facilitate the translation of recording
into text.
Key features for clearing records off outside noise
and interference are in the «Processing».
Presets
If you have several records made in the same
conditions, adjusting the settings to process one of
them, you can save it as a template (a preset) and
apply it to the others.
Directivity Control
If you use a recording made by the recorder with
more than two audio channels (e.g. Edic-mini Ray
A36), there is the option to control the direction
of the speaker's voice (the source of the desired
signal) in manual or automatic mode, suppressing
signal from other directions as much as possible.
Noise Suppression
With this function, you can reduce the level of
background noise in the recording. The greater the
value on the regulator, the higher noise level is cut
off. Keep in mind that together with the noise useful
low-amplitude signal can also be cut off.
Low-pass filter
This function can be used to cut all the frequencies
in the signal above predetermined level. This is
very useful, for example, when reducing the impact
on the recognizability of speech frequencies
outside the range of speech.
Equalizer
Allows it to operate signal spectrum flexibly,
«drowning» or «pulling» the signal in a certain
frequency band. For example, this feature can be
used if necessary to suppress low-frequency noise
when recording in transport.
Automatic gain control (AGC)
This feature allows the audio signal to acquire
a certain level strengthening weak signal. The
degree of «pulling» the signal is specified with the
regulator control. This function is applicable when
processing telephone line recording, in which the
original signal amplitude at the other end of the line
is much smaller.
Compressor
This option reduces the dynamic range of
the original signal. It is used to improve voice
intelligibility.
