ESP32-S3 for real-time 4-channel TDM acquisition + tachometer + FFT + Wi-Fi?

[azaroual]

Hello,
I am evaluating ESP32-S3 for a project with 4 synchronous channels at 25.6 kSPS/channel using TLV320ADC6140 in TDM mode, plus a synchronized tachometer input, real-time FFT, buffering, and Wi-Fi transmission.
I know the device supports I2S/TDM and DSP, but I would like feedback from engineers who have used it in similar real-time systems.
Is this architecture robust in practice, or are there important limitations regarding timing, DMA, buffering, or Wi-Fi interaction with acquisition?
Thank you.

Should work no problem.

The only potential timing issue I see is if you intend to write to flash (NVS, file system,...), which can basically stop the whole chip for a few tens of milliseconds.
