Introduction
Voice capturing, telephony, and voice-over-IP are improved by algorithms based on signal processing and perceptual modeling.

Stationary Noise Cancellation
Capsule noise, electric noise, electronic noise, and environmental acoustic noise are removed from microphone signals. Alternatively, also transducer/loudspeaker signals can be pre-processed to reduce noise in the playback. Audio artifacts are minimized by employing perceptual principles.

Enhanced Acoustic Echo Cancellation (EAEC)
EAEC is a patent pending high performance echo control technology. The low computational complexity of EAEC makes it suitable for handsets for standard and wideband handsfree voice calls. EAEC is also applicable for next generation high-end teleconferencing, supporting sampling rates up to 48kHz and mono/stereo/multi-channel.

Multi-Microphone Voice Capture
Patent pending multi-microphone beamforming and non-stationary noise suppression algorithms enable a new level of conversation comfort. The use of this technology with two microphone capsules enables removal of non-stationary environment noise, de-reverberation, and improved handsfree operation.
