Sound source distance estimation with Seeedstudio product

I am trying to build a robotic demo project which needs “sound source distance estimation” function, which Seeedstudio product should I choose to fulfill this need?

Typically sound source localization should contain information about sound direction of arrival (DOA) and sound source distance estimation (SDE). I understand DOA is achievable with Seeedstudio product, how about SDE?

Dear Customer

We have two versions of DOA. ,,I’m sorry, we don’t have SDE.
