Audio Signal Processing

Since our beginning as the Digital Signal Processing Directorate of SPARTA, Inc., Signalscape has grown to be a leader in streaming audio processing software.

We implement DSP algorithms for embedded processors as well as Windows-based applications. For Windows, each algorithm is implemented as an ActiveX filter component under Microsoft’s DirectShow streaming multimedia architecture. This allows easy technology re-use and rapid prototyping of real-time audio processing software. Signalscape’s audio processing technology is used in surveillance and forensics applications including:

Microphone array beam forming
Sound localization
Signal separation and cancellation
Noise reduction
Intelligibility enhancement
Signal identification

Image and Video Processing

Signalscape develops state-of-the-art image and video processing algorithms and deploys them in surveillance and forensic video applications. Our unique video processing filters provide customers with video clarification and analysis capabilities that no other product can match. Signalscape’s image and video processing technology includes:

Noise reduction
Interference removal
Motion estimation/stabilization
Blur reduction
Contrast enhancement
Multi-camera signal demultiplexing
Video compression
Pattern recognition
Motion tracking
Real-time video processing
