bdAEC for Cortex M - Acoustic Echo Canceller by bdSound

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

bdAEC for Cortex-M is intended for application based on Cortex-M3, Cortex-M4 and Cortex-M4 with Floating Point Unit. The most typical applications for bdAEC for Cortex-M are systems without Operating Systems or running simple RTOS, like:

• handsfree phones
• desktop phones
• intercom systems
• hardware switchboard
• webcams and audio capture devices
• custom communication systems
• automotive handsfree systems

Main Features

• Full duplex Acoustic Echo Canceller
• Wide band support (up to 16kHz 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

• Bare Metal
• RTOS

Scalable Solution

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