The Real-Time Multi-Channel Audio Bridge has the ability to send and receive audio between a sound card and T1 E1 timeslots. Real-Time Multi-Channel Audio Bridge application provides a bridge between T1 E1 timeslots and single or multichannel sound card(s).

The application allows user to insert speech onto T1 E1 timeslots using the PC microphone.

Also, listen to speech on T1 E1 timeslots using PC speakers or Headphones. This application is available as a part of basic applications with all T1 E1 analyzers.

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).

In addition, as shown in the diagram, linear PCM can be converted to G.726 (40 kbps, 32 kbps, 24 kbps, or 16 kbps), and G.722 (64 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)
  • Supported codecs data rates are - a-law, µ-law, 16-bit PCM (Intel), 16-bit PCM (Motorola), MS Wave, G.726 (40 Kbps, 32 Kbps, 24 Kbps, and 16 Kbps), and 14-bit 16 KHz G.722 (64 kbps)
  • 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 /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
