SIGNAL PROCESSING

voice INTER connect offers services around the whole transmission chain of audio and video data.

• Data acquisition: analog and digital microphone signals, multi-channel microphone array for spatial filtering and preparation of beamforming or source localisation, support of ethernet-based cameras
• Data transmission: own audio / video / data bus (2-wire, fully flexible), embedded audio / video streaming, audio / video compression
• Data processing: beamforming with microphone arrays, acoustical source localisation (ASL), acoustic echo cancellation (AEC) plus residual echo cancellation, noise reduction (NR), voice activity detection (VAD), audio quality enhancement (EQ, compressor, gate), video quality enhancement, embedded video codecs
