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!
