128-band adaptive noise reduction
adaptive feedback cancellation
Description
Venture is Gennum's premiere DSP product designed
on the Voyageur鈩?platform. Combining the power and
capabilities of Voyageur together with SoundDesign
Advanced Research, Venture delivers cutting-edge
features and high performance.
Voyageur is Gennum's industry-leading programmable
digital signal processing platform. SoundDesign
Advanced Research is a Gennum developed
methodology that couples state-of-the-art acoustic
algorithms to ensure high-fidelity digital sound quality.
Venture's adaptive noise reduction preserves perceived
speech levels without causing distortion. It monitors
noise levels independently in 128 individual bands. This
strategy also employs advanced psychoacoustic
models to eliminate audible noise and reduce the
amount of perceptible artifacts introduced by the noise
reduction process.
Based on a phase cancellation method, Venture's
adaptive feedback reduction algorithm provides
increased maximum stable gain unlike other feedback
strategies. Additionally, it features rapid adjustment for
dynamic feedback situations and resistance to tonal
inputs.
In addition to these adaptive algorithms, Venture also
supports the following features: FRONTWAVE
directional processing, cross fading between audio
paths for click-free memory changes, 8-band graphic
equalizer, 8 generic biquad filters (configurable as
parametric or other filter types), programming speed
enhancements, optional peak clipping, flexible
compression adjustments, programmable tones for
memory change and low battery indicators, wideband
gain, volume control and industry-leading security
features to avoid cloning and software piracy.
