Multi Stream Synchronization
What is Multi Stream Synchronization?
In the realm of digital audio processing, maintaining synchronization between audio streams operating at different sample rates is crucial for seamless integration and optimal performance. Dolphin’s Advanced Asynchronous Sample Rate Conversion (ASRC) hardware IP offers a robust solution to overcome this challenge, ensuring smooth interoperability across diverse audio systems and devices.
What are the key parameters in Dolphin ASRC IP?
High fidelity conversion:
It is important to do high fidelity sample rate conversion preserving the integrity of audio signals without introducing artifacts or distortion.
Flexible configuration and wide range of sampling rate
It is important to have a flexibile solution to adapt to various audio processing requirements and connectivity protocols, allowing for tailored solutions to suit specific application needs.
Synchronization
By precisely aligning audio streams operating at different sample rates, hardware ASRC IP ensures reliable synchronization, enabling seamless integration and interoperability across heterogeneous audio systems and devices.
Clock compensation
it is necessary to synchronise the clocks between different clock domain, such as connectivity, the audio codec and the processing. Clocks in SOCs are rarely very accurate, so the ASRC hardware can compensate for error in clocks deviation.
