BIGSPEED Voice Compression SDK is a uncomplicated, low-complexity, low-cost articulation engine for quick evolution of VoIP applications. It incorporates audio recording / playback and articulation condensation / decompresion in a single COM automation object, along with some advanced articulation processing features.

The used audio format is wideband, 16kHz, 16Kbps, PCM. The condensation ratio is adjustable and toilet vary from 4: 1 to 50: 1.

A portion of bandwidth toilet be addionally saved thanks to the muteness condensation. A articulation activity detector (VAD) with an adjustable threshold rase is used to key between regions with normal speech activity and those with muteness or backdrop haphazardness.

An optional echo suppression toilet be employed thanks to the robust duplicate talk detector. When a duplicate talk office is detected, the output indicate is faded (half-duplex).

An automatic gain moderate (AGC) organisation is implement with a dynamic range 10: 1. A haphazardness reduction is performed on the microphone indicate to minify the gabardine haphazardness.

BIGSPEED Voice Compression SDK utilizes an elegant event-driven paradigm for sluttish integration into Windows applications. A special attention is paid to ply responsive user interface while maintaining downhearted CPU exercise. Carefully designed placed of properties, methods, and events offers great flexibility to germinate innovative communication software. Sample applications are included in Visual Basic .NET, and Delphi 7.
