Audio and Voice Solutions

Product Description

 

bdAEC - Acoustic Echo Canceller is the field proven solution to deal with echo issues arising from acoustic coupling between loudspeakers and microphones.

bdAEC supports different ARM cores with the following products:

• bdAEC for Cortex-M : solution for application based on Cortex-M family processors
• bdAEC for Cortex-A: solution for application based on Cortex-A family processors with NEON or VFP

bdAEC for Cortex-A is intended for a wide range of application based on ARM Cortex-A family processors with NEON and running complex operating systems like Linux, Android and iOS. Typical application includes:

• embedded systems
• professional conference unit
• mobile phones and tablets
• advanced intercom systems

Main Features

• Full duplex Acoustic Echo Canceller
• Ultrawide band support (up to 32kHz of sample frequency)
• Multipoint conference support
• Fast engine tracks immediately any change in acoustic path
• Handle echo paths with negative ERL (gain from speaker to microphone)
• Always stable
• Double Talk Detector
• Voice Activity Detector
• Adaptive residual echo canceller
• Very low CPU consuming

Supported Operating Systems

• Android
• iOS
• Linux Embedded

Scalable Solution

bdAEC for Cortex-A can be integrated with other bdSound technologies for audio devices management and for speech processing (like equalizers, noise reduction, dynamic range control).
