The airlyra SPA101 is a highly integrated system-on-chip with Bluetooth^® Version5.3, audio decoder and audio post-processor and memory. It is mainly composed of a M4, and 32-bit DSP processor and memory. The high performance DSP, is 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.

The SPA101 is delivering an excellent audio solution in a way that makes it implementation convenient, function complete and cost effective -- provides the fruitful interfaces and tools for system easy to bring-up, features the high performance and powerful processing ability in audio functions, and even embeds a lot external parts containing memory for much simplifying the bill of materials on system. Most importantly, SPA101 is born to offer a perfect solution to the developer in producing the best cost-performance Home Audio for the upcoming growth markets
