Audio Sample Rate Converter
- The ASRC core is a compact and high-performance audio sample rate converter.
- It accurately converts digital audio signals between different sample rates while maintaining signal integrity and minimizing distortion.
- Supporting both asynchronous and synchronous conversion modes, the low latency ASRC can be used in real-time streaming applications as well as in high-speed batch processing environments.
