Hi, has anyone tried the SPEEX implementation for esp32 ?
https://github.com/UncleRus/esp-idf-speex
It should have noise reduction and reverb reduction tools, which would be useful for diy voice projects

@weary nimbus Hi, I noticed your speex discussion here: https://community.rhasspy.org/t/question-would-anyone-be-interested-in-a-open-source-dsp-mic-array/4941/2
I'm trying to get rid of reverb in a homemade voice project.

Question: would anyone be interested in a open source DSP mic array?

Hi @Alextrical! I saw your post over in the HA forums. I’m definitely interested 🙂 I know the Lyra-T used the ZL38063, but I’m curious if you’ve considered other chips. The XMOS XU316, for example, seems to be capable of similar things (echo cancellation, noise suppression) but also some machine learning applications like wake word detection. ...

I was wondering if you could share some of your work.

Sure, but it's in a partially working state since I was trying out various things. I don't have the time to clean it up right now, but I can share it if you're still interested.

trying to make it work.
I'm not much of an expert.
maybe you have some yaml code with your experiments?

#

I moved the folders and enabled the external component.
