Voice Communicator (VC) components were designed to simplify the development process of audio streaming applications, such as voice chat, voice conference, and similar VoIP software. They provide real-time low latency multi-client audio streaming over TCP/IP networks and include efficient components for sound recording, playback, encoding, decoding, mixing, resampling, and TCP/IP server and client components for peer-to-peer, multi-client, broadcast, multicast and conference-like audio communications.

 

Thoroughly designed components cover low-level details of audio processing, as well as network communications. Unique provider-consumer relation feature makes it easy to build any complex audio data flow in a few seconds. It also dramatically reduces the amount of source code needed to be written.

Key Features

  • low latency real-time multi-threading audio processing
  • transparent audio compression and decompression
  • peer-to-peer, broadcast, multicast and conference streaming support
  • supports reading, witting and streaming of WAV files stored on disk
  • simple script interpreter
  • supports several external libraries for MP3/Ogg streams processing
  • all components are compatible with VCL and require no special knowledge for usage

Additional Features

Efficient components for audio encoding (compression), decoding (decompression), mixing and resampling make it easy to keep control over audio stream quality and format. ACM (Audio Compression Manager)--standard Windows component installed by default on all multimedia computers is used for audio encoding. VC components do not require DirectX technology.

It is also possible to convert PCM streams into MP3 or Ogg/Vorbis with easy to use Delphi class wrappers for external encoders. Following external engines are supported:

Advanced audio processing tasks, such as tempo control, pulse tone generation, channel extraction and swapping, volume adjustment, and others are included in VC demos package as pre-compiled binaries ready for download.
