Portable, re-entrant and re-locatable library code. Comfort Noise Generation (CNG) with noise matching feature. Stereo and Multiple Mic Modes available. Configurable narrowband(8kHz), wideband(16kHz), super-wideband(32kHz), fullband(44.1kHz,48kHz), and high-resolution fullband(96kHz) sampling rates. Long configurable echo tail length (up to 512ms). Advanced double talk detection with low divergence during double talk. Fast re-convergence for echo path changes. Optimized for ANSI C and leading architectures. VOCAL’s AEC and noise control library module can be used in nearly every acoustical environment to achieve to achieve highly intelligible and clear, echo-free communication. A well-designed Acoustic Echo Canceller should be able to be easily integrated into a wide variety of acoustic environments with different levels and types of perceived echo paths and background noise. Compared to line echo cancellation, acoustic echo cancellation is much more complex because the number of reflections is greater and the high variability in the echo path of the acoustic environment. In any audio system that exhibits sound feedback from the loudspeaker to the microphone, acoustic echo cancellation can be applied to remove the unwanted echo from the audio signal. #Atlas acoustic echo cancellation software#
Acoustic echo cancellation removes echoes caused by acoustic coupling and environmental acoustic effectsĪcoustic Echo Cancellation (AEC) software can be applied to hands-free telephone systems, conferencing speakerphones, IP intercom systems, V2oIP videoconferencing systems, aeronautical headsets, and smart speakers. This software can be applied to audio applications with sampling rates ranging from narrowband (8kHz), wideband (16kHz), and fullband (48/96kHz). VOCAL’s Robust Acoustic Echo Canceller software is platform independent C code, and is available for a wide variety of platforms, including ARM, Intel, ADI DSP, TI DSP. VOCAL’s AEC with speech enhancement features provide high definition and high-fidelity audio quality for full-duplex audio communications. Beyond adaptive filtering, double-talk detection, residual echo suppression, VOCAL’s AEC SDK can include features, such as noise reduction, anti-howling, automatic gain control and automatic delay estimation. VOCAL’s Robust Acoustic Echo Cancellation (AEC) software is an efficient, portable, customizable full-duplex Acoustic Echo Canceller solution for removing echoes caused by acoustic coupling and reverberations between the microphone and loudspeaker in the voice.
