Network Audio Logger

The Sonifex Net-Log is a 4 channel audio logger which can record weeks of programming on a large internal hard-disk. The unit was designed as dedicated hardware for reliability reasons, i.e. there’s no PC motherboard in this machine. Although PC based systems are great for playback, they generally aren’t robust enough for continuous recording 24/7/365. The Net-Log was designed from the ground up to offer :

•High reliability for continuous operation.
•High quality audio (mpeg compressed).
•Compatibility with existing broadcast
•Windows based systems (bwf files can be saved).
•Automatic operation with very simple to use software.
All audio created by Net-Log is Windows Media Player™ compatible so files can be emailed to colleagues and customers and played out on any PC with a sound system.

There are many applications for Net-Log, from radio stations recording their broadcasts for regulatory purposes, to small call centres, law firms and security companies using them for monitoring. Net-Logs have been installed in court rooms & police interview rooms for audio surveillance and, when combined with the D:Scribe transcription system, offer a cost saving desk-top based logging & filing system for audio & transcripts.

Key Features of Net-Log

•Dedicated reliable multi-channel recording hardware.
•Easy 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 12 months together with two channels of high quality logging for 1 month, on one machine.
•Record inputs can be controlled remotely, e.g. snoop recording from mic-live output of a mixer.
•Automated 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 recording.
•Up to 250,000 recordings per channel can be made.
•Each Net-Log has its own IP address, so a number of machines can be installed on the same network.
•Fail-safe alarm indicators and remotes.
•Password protection and security access rights to system.
•Support for hard disk sizes up to 2048GB.
•Recordings 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 speech.
•Recording on Net-Log can be controlled serially by Crestron and Televic board room controllers.
