alt Hacker NewsYes this is an older codec but it has been reliably in production for around 20 years, and has a high channel count to cost ratio. The specifications are not cutting edge but I get comparable performance to my trusty Saffire Pro 40.
I have my eye on some other codecs for the next project.
I'm curious what you mean about the STM32H7. My experience has been that it is a challenging part, at least partly due to bugs in the HAL. This is especially true for the ethernet implementation. But once it is working the performance is quite good.
