SILK
SILK is a superwideband audio codec for real-time, packet-based voice communications. SILK targets a diverse range of operating environments and provides dynamic scalability in several dimensions on a frame-by-frame basis. It adapts to network conditions through dynamic control and/or use of bitrate, packet rate, packet loss resilience and discontinuous transmission (DTX).
The ESPICO implementations are highly optimised, realising low memory and MHz requirements. Contact ESPICO for specific resource requirements.
