Working with microphones via I2S
201 USD Connect 4 microphones via I2S, reading data through DMA.
Data must be read at exactly the same time to compare recordings of the nearest milliseconds and understand which microphone received the data first. The controller has 2 I2S to which 4 microphones can be connected (2 microphones to each I2S; using Left/Right channels)

Good day.
Yes, this task can be implemented.
4 I2S microphones are connected via 2 hardware I2S interfaces (2 channels Left/Right each), reading data through DMA with synchronous triggering, which allows obtaining time-aligned samples and comparing which microphone received the signal first.
To correctly assess the timelines and implementation, please let me know:
– which microcontroller is planned (ESP32 / STM32, model)?
– which specific I2S microphones?
– desired sampling frequency?
… – what exactly is needed at the output: raw data or already the logic for determining the "first" microphone?
After this, I can propose a specific architecture and implementation plan.
In any case, feel free to write for discussion.

Hello,
regarding the controller - we are clarifying, + additionally - in what form or format the result should be, whether there should be cross-correlation from the stream and other things - everything is in the correspondence.

так а что вы конкретнее хотите? программиста или схемотехника?
