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.
-
24-bit -130dB THD+N Multi-Channel Audio Sample Rate Converter
- This core can be used to interface digital audio equipments operating at different sample rates.
- It has been designed for systems requiring very high quality in terms of low harmonic distortion and noise, tolerance and rejection of input jitter.
-
16-bit -90dB THD+N Multi-Channel Audio Sample Rate Converter
- This core can be used to interface digital audio equipments operating at different sample rates.
- It has been designed for systems that require a low-cost solution, maintaining low harmonic distortion and noise, and a high tolerance and rejection of input jitter.
-
16-bit -90dB THD+N Multi-Channel Audio Sample Rate Up Converter
- This core can be used to interface digital audio equipments operating at different sample rates.
- It has been designed to work only in “up-sampling” mode for systems that require a low-cost solution, maintaining low harmonic distortion and noise, and high tolerance and rejection of input jitter.
