The airlyra SPA300 is a highly integrated system-on-chip with high-definition audio decoder and audio post-processor. It is mainly composed of a 32-bit RISC microprocessor, an 8-bit I/O processor, and multi-core 32-bit DSP processors. The high performance DSPs, are capable of audio decoding, sample rate conversion, and audio post processing such as bass enhancement and virtual surround sound, as well as a built-in audio signal flow is provided for speaker compensation, including bass/treble tone control, PEQ, crossover filters, bass management, and DRCs, which normally found only in high-end professional audio equipment to deliver unsurpassed sound effect.
