Nope that is where things are quite raw but community based.
Its not a chip its embedded functionality and the datasheets can be quite hard work but are essentially a gold mine.
I2S Inter-IC Sound has up to 16 channels I can only verify 8 in and 8 out.
PDM 8 input with 2 channel dac output
8 channel ADC with 2 channel dac output.
These are on on the RK3308 silicon with a codecs built in.
DSP 4 channel VAD on 1st channel that in sleep mode uses first channel to trigger wake, which surprised not seen some sort of monitoring. battery operation @ 1.1Ghz .
The rest is pretty much raspberry like minus hdmi but a SPI display can be used, same with camera as usb can be used.
Its Debian based there is Ubuntu but debian is far more conservative and currently very much like a 64bit Raspbian OS.
I am beginning to think there are so many great features on this SoC it was a mistake to use 2x26pin headers.
It has strong potential for VoiceAI projects such as https://mycroft.ai/ https://community.rhasspy.org/ or https://github.com/voice-engine/voice-engine.
Crazy robot projects where Keyword / AI makes a far more interactive intelligent product.
Its really well specified as Pi3 is really the bare minimum for much voice AI and that is where it approx stands with some interesting audio frequency interfaces that may not be strictly audio.
Its RockPiS vs Pi3A+ and from that take your pic.
At the same clock speed the Cortex- A35 reaches 80%-100% of the performance of a Cortex- A53 Pi3 depending on the workload; it only consumes 68% of the available power when doing so.
The VAD to wake from sleep on the spectral energy on a single input probably means it has many low power monitoring applications.
