- Radio Broadcast Logging
Where logging is required by the authorities, Net-Log provides
a perfect, simple to use, elegant solution providing playback
of requested recordings within seconds. But even if logging
isnt regulatory, Net-Log can still deliver audio to the
desktop of anyone at a radio station you dont need
to go to the racks-room, or central technical area to play out
a recording previously made.
So it has the following advantages:
their desktop, the sales team can check to make sure that
advertising was played on time and can create audio files
to email to customers.
controllers can snoop on their presenters, checking performance
and checking that scheduled music was played.
managers can check up on their competition and compare it
with thesound of their own station.
production team have much easier access to recorded audio
from past radio shows for the preparation of future stings
records in mpeg layer 2, the standard for radio broadcasting,
so that you can be sure that audio files created using Net-Log
are compatible with almost every mpeg based automation system
available. Additionally, broadcast wave format (bwf) files
are supported as standard, ensuring tight integration with
your playout systems.
- Key Features of Net-Log
reliable multi-channel recording hardware.
to use Windows remote operation for playback, archiving,
streaming and configuration.
Independently configurable channel pairs to record at different
sample rates, different bit rates and in mono or stereo.
Recording duration configuration of the channels to suit
your needs, e.g. 2 channels of low quality logging for 6
months together with two channels ofhigh quality logging
for 1 week, on one machine.
inputs can be controlled remotely, e.g. snoop recording
from miclive output of a mixer.
voice recording - each channel can start and stop recording
automatically by setting audio threshold levels, which means
that it can be used for voice controlled systems and telephony
to 250,000 recordings per channel can be made.
Net-Log has its own IP address, so a number of machines
can be installed on the same network.
alarm indicators and remotes.
protection and security access rights to system.
for hard disk sizes up to 2048GB.
can be made using optional G.729 algorithm, allowing longer
recordings and lower network traffic. G.729 audio quality
is comparable to MPEG L2 at 32kbits/sec when used to record/playback
on Net-Log can be controlled serially by AMX, Crestron and
Televic board room controllers.
- Hardware Description
Net-Log is a 1U rack-mount unit which has 4 mono record inputs
on 3 pin XLR sockets with potentiometer gain controls and LED
level indicators for each input. These accept 2 stereo, or 4
mono audio streams which are encoded in mpeg layer 2 format
and written to a large internal IDE hard disk drive. The size
of the drive is continuously being increased as technology improves
and Net-Log can support sizes up to 2048GB.
Net-Log has 2 serial ports on 9 pin D-types which are used to
program the IP address of the machine and to upload new software.
Additionally, there is a 15 pin D-type connector used for remote
input recording control and for alarm outputs (hard disk failure
and archiving warning).
A 10Mbps RJ45 network port is used to connect Net-Log to your
PC network and audio is streamed using TCP/IP. Audio can be
streamed simultaneously to one, or many, PCs, as well as simultaneously
archiving audio data to an IP server automatically in the background.
All the Net-Log configurations and operational features are
controlled from a connected PC using the Net-Log-Win software.
- Net-Log-Win Software & Licensing
The Net-Log is initially configured and controlled by Net-Log-Win
software which is a suite of three applications which run under
MS Windows 98/ME/NT/2000/XP. The software is sold either
as a two stream, or a five stream licence. This means that each
Net-Log on a network can simultaneously support either 2, or
5 simultaneous connections to it for playback or archiving.
Note that you dont need to buy a licence for each Net-Log
if they are on the same network - if you have a number of Net-Logs
on a single network, you only need to purchase a single set
of licences, e.g. if you have 3 Net-Logs and buy a single Net-Log-Win05
5 stream licence, up to 5 different people can stream from each
of the 3 Net-Logs, i.e. 15 separate streams, provided that your
network infrastructure can allow for this.
Additionally, this is a buy once licence - we dont ask
you to re-buy it each year ! Net-Log licensing operates by you
providing us with a licence code which appears in a licence
window within Net-Log-Win. Once weve verified the authenticity
of your order, we send you an authentication code which you
enter into the licence window to licence your Net-Log. If you
dont have a licence code, the Net-Log will continue recording
but access to the recordings will be denied after 3 days.
- Net-Log-Win Software
There are 3 PC applications used to configure and control
- This is the application used on a day to day basis to
control recording and playback.
- This is used to automatically archive/backup files to
an IP server.
- A utility mainly used to initially configure the Net-Log
and solve connection problems.
- Net-Log-Win Application#FF0000
There are 4 main screens in Net-Log-Win which control and
configure the connected Net-Log(s) : Recording, Playback,
Archiving and Options. Access to these screens can be password
protected and users can be configured either to View or Edit
each screen. In the top part of the screen, a drop down list
allows you to select which Net-Log you wish to connect to
and the alarm states are also shown.
The Options screen is the place where you configure the settings
of the connected Net-Log. The Options Archive screen in Net-Log-Win
is used to configure the IP addressand directory of the archiving
destination and also to define archives to be written either
as the cuts were recorded, or in files of a certain duration,
Unlike normal hard-disk recording systems which stop when
the disk is full, on reaching the "end" of the recording
data space Net- Log begins to overwrite the oldest recordings,
meaning that you always have access to the last recordings
made, up to the size of the hard-disk. Additionally, it allows
simultaneous recording and playback, so that you dont
have to stop the unit recording in order to search and play.
Each channel can be given a service name for reference when
searching for audio.
Recording can be controlled in 5 different ways:
on-screen buttons in the Manual Record screen.
the Program Record screen to start & stop recording
at different times, using up to 20 programs. Programs can
be saved to disk.
a remote input on the 15 way D-type connector.
on voice/sound level, ideal for recording telephone conversations,
configured in the Options Record screen.
AMX, Crestron and Televic board room controllers, via an
RS232 serial connection.
The controllers are mainly used in meeting rooms and allowing
Net-Log to more easily be used for recording in this environment.
Net-Log-Win software for MS-Windows 98/ME/NT/2000/XP
is used to listen to audio recorded at a previous time and
date, or for copying audio to a file, e.g. to email to a client
In the Play screens, simply select a Net-Log and the required
channel service name and a list of all the recordings made
are displayed, sorted by recorded date and time. There are
4 ways to play audio:
the Play Stream screen, selected audio is played out on
your PC sound system within seconds.
the Play Download screen, you can select a recording's date,
time and duration and a file is downloaded from the Net-Log
and created on your local PC. You can then use separate
applications to email the audio file, edit it, or save it
to CD, or DVD. Files can be saved as .mp2, .mp3 or linear
the Play Program screen, you can select a number of recordings,
made at the same time over a number of days of the week
and save them off to a single directory, e.g. for storing
commercials from a particular customer. Files can be saved
as .mp2, .mp3 or linear .wav.
the Play File screen, you can open any previously saved
audio file for playback. You can also play .mp3 and linear
.wav files this way.
a separate free player is available within Net-Log-Win to
play any audio file created from a Net-Log.
use the Archiving function to automatically create long-term
backups of the recordings by streaming audio to a separate
server disk for archival purposes.
For each recorded channel, you can define an IP address and
directory to save files to and Net-Log can create files on
that directory either in the same way that they are recorded,
or in files of a certain length, e.g. of 1 hour duration.
The Net-Log Auto-Archive utility is run on the server that
you are archiving to. It has the following features:
connection to multiple Net-Logs.
log-in, archive and log-out process.
display of Net-Logs on-screen in an easy to understand format.
reports, error reports and archive alarm information can
be emailed automatically at regular intervals.
be used to check the status of Net-Logs even when archiving
is not used or required.
that Archiving uses a licence stream.
- Net-Util Application
The Net-Util program connects to a Net-Log unit via a serial
(COM) port using the supplied serial cable.
Net-Util is used to :
the IP address of the connected Net-Log.
new firmware into the Net-Log.
downloading audio from Net-Log you can now download in .mp3
and linear formats, as well as the native .mp2. Audio data is
converted on-the-fly as you download.
