Testing microphone (INMP411) capabilities with ESP32 modules.
- Sound level: measure the intensity of sound in decibels (dB): volume2.cpp
- Does my other INMP441 microphone work?
- No, because it's not INMP441.
- Make it work on ESP32 and ESP32-C3
- Frequency analysis: analyze the distribution of sound across different frequencies
- Sound localization: determine the direction of the sound source (need multiple microphones)
- Noise level: how much the sound is disruptive to humans
- (OPT) Sound classification: identify specific sounds (e.g., glass breaking, dog barking)
- (OPT) Voice recognition: identify specific voices or commands
