GL Communications Inc., announced the release of its latest product Real-Time Multi-Channel Audio Bridge software. Briefing the media, Mr. Jagdish Vadalia, Senior Manager of Development, said, “The ability to send/receive from a sound card directly to T1 E1 timeslots is available once again for the latest HD cards, USB units and Universal Analyzers.

The application allows one to listen to T1 E1 timeslots directly on a PC speaker or insert Microphone or Line In signals into T1 E1 timeslots”. He added, “That's not all! This powerful optional application can also interwork with other sound card aware applications like Goldwave, Cool Edit, Adobe Audition, Audacity, Matlab, LabView and many others. In this case, third party virtual sound card software is required, e.g. VAC (Virtual Audio Cable)”.

Mr. Vadalia, further added, “Real-Time Multi-Channel Audio Bridge is an application that provides a bridge between T1 E1 timeslots and single or multichannel sound card(s). In addition, as shown in the diagram below, linear PCM can be converted to G.726 (40 kbps, 32 kbps, 24 kbps, or 16 kbps) for direct insertion into T1 E1 timeslots, instead of the usual u-law or A-law”.

Main Features

Insert speech on T1 E1 lines using microphone connected to the sound card i.e., stream audio to channel/subchannel from the sound card

Listen/Drop speech on T1 E1 lines using PC speakers or Headphone using sound card - Stream audio from channel/subchannel to sound card

Supported codecs are A-law, Mu-law, 16 k Linear PCM, G.726 40 Kbps, 32 Kbps, 24 Kbps, and 16 Kbps data rates, G.722 (enhancement soon)

Mono and Stereo audio modes supported

Configure Drop and Insert, codec type, Mono/Stereo Audio Mode, port, Channel, Subchannel for a sound device

Automatic detection of sound devices including Virtual Audio Cable (VAC)

Applications

Audio editing applications like Gold Wave, Adobe Audition that normally send or receive audio streams to and from a sound card can be directed to timeslots on GL's T1 E1 cards

Real-time transmit streaming from sound card and viewing of receiving stream

Trouble shoot audio problems on T1 E1 timeslots

Playback and record mono or stereo signals with audio editing applications directly from T1 E1

Audio editing features/special effects such as noise reduction, delay, echo, fade, equalization can be performed with sound aware programs

Supports non-contiguous timeslots for performing Drop and Insert actions
