Audio Reactivity - best FFT/FHT library for the ESP8266?

Hi everyone. I’m working on audio response for a project and was wondering what are the current best libraries to use for audio spectrum analysis on the ESP? I attempted to use one of Andrew Tuline’s demos with FHT, but the FHT library won’t work (http://wiki.openmusiclabs.com/wiki/ArduinoFHT). I get an error avr/pgmspace.h: No such file or directory.

Some workarounds I found have also failed (such as removing the avg/ in the FHT.h file), so I’m assuming this library is incompatible with the ESP. The question then is what are the best libraries for audio spectrum analysis and audio reactivity on the ESP8266? I can search around and find a few, but if anyone here knows of some particularly good libraries and/or examples, please let me know. Thanks!

This one appears to work on the ESP8266, buy I’ve not tried it …

look to this project:


But I can’t try it, because I don’t understand how to burn ESP.
If you could - please write for all ))
Thanks!

@fa25514ad7a4d6321c2d colorchord is very interesting, one day I’ll try and port it to the ESP32

@Jeremy_Spencer Thanks for the link! Kosme’s library seems like one of the few that works, so I’ll give it a shot.

@fa25514ad7a4d6321c2d colorchord looks interesting, but also a bit of work to set up. Neat functionality though, so I’ll look into it. Thanks!
