The bdSES (Speech Enhancement Suite) is a complete set of highly optimized algorithms for VoIP software applications. It includes an advanced Full Duplex Acoustic Echo Canceller and a distortion-less Noise Reduction.
bdSES is specifically designed for Softphone applications where the PC-based environment and the inherited sound-card and net delay handling problems required a strong and robust solution.
Thanks to easiness of integration and the ready-to-use API, bdSES is the right solution to
quickly develop a VoIP application with outstanding performances.
The sample frequency up to 32kHz and the uncompromised sound quality are important factors kept in consideration by bdSES both for a consumer and a professional application.
bdSES is ready for a multipoint conference and manage the different channels activity maintaining the speakers’ voice clear and loud, adapting the downmixing level according to the conversation status.

The following block diagram describes the top-level view of the bdSES Speech Enhancement Suite.

To discover the functionality of each block just move the mouse pointer on a block; a tooltip with a short explanation will appear. Some of them contain a link to detailed description.

In order to let you experience the quality of a VoIP application based on bdSound Speech Enhancement Suite (bdSES), we have designed a simple SoftPhone working with bdSES. The definitive way to test the performance of a VoIP software speech enhancement algorithm is to use it in a real-life environment, with any device (stand alone microphones, headsets with microphone, webcams' microphones, pc speaker, etc.) in an actual two points communication.
