PureAudio®
PureAudio® is a noise canceling algorithm that enhances speech-centric applications by sampling
an ambient noise environment and attenuating the noise sources around the desired
speech signals, delivering a pure audio signal. Continuous and repetitive noise is effectively
removed from the audio input, providing higher recognition rates and improved communications.
Designed specifically to improve signal-to-noise ratio, PureAudio works best in canceling
stationary noises such as computer fans, engines, tire noise, etc.
Market Applications
PureAudio enhances a wide variety of speech-centric market applications including desktop
speech recognition, cellular, Internet telephony, videoconferencing, multi-player gaming,
voice verification, voice chat, surveillance, automotive telematics systems, wearable computers,
military and embedded devices. In essence, PureAudio can be applied to any audioinput.
Integration
PureAudio can be embedded directly into an application or device, but more importantly,
PureAudio is scalable to the user environment. Andrea Electronics can deliver an algorithm
to cancel 8 dB of noise or 18 dB of noise, designed specifically to meet your application
needs. PureAudio can run on a Digital Signal Processor (DSP), Pentium® or any other PC
processor.
PureAudio can run as an independent noise canceling algorithm for single-element microphone
solutions, or enhance a host of Andrea Electronics' digital solutions including DSDA®,
(far-field Digital Super Directional Array microphone). Together with PureAudio, this algorithm
offers an advanced system of increasing signal-to-noise ratio and providing an optimum audio
input solution. |
