ASRC IP
ASRC IP cores (Asynchronous Sample Rate Conversion) convert stereo audio from one sample frequency to another. The input and output sample frequencies can be an arbitrary fraction of one another or the same frequency, but based on different clocks. The output is a band-limited version of the input resampled to match the output sample timing.

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.
