Acoustic Echo Cancellation (AEC) for IP & Speaker Phones

SoftEcho for IP & Speaker Phones is a robust echo cancellation software solution. Readily portable to the processor of your choice, this solution is optimized for hardware IP phones, desktop conferencing and speakerphones as well as intercoms.

SoftEcho's high-performance algorithms provide excellent sound quality by completely eliminating echo caused by acoustic feedback while ensuring unconstrained full-duplex conversations. Moreover, SoftEcho offers a 128ms echo tail to ensure that the entire echo is eliminated, even in large conference rooms where the voice signal takes longer to reflect off the walls before being picked up by the microphone as echo.

A cost-efficient, low footprint solution, SoftEcho is also easy-to-integrate. IP phone manufacturers can leverage Octasic's proven expertise in audio processing to deliver industry-leading sound quality to market faster.
