multi-band equalizer

[malaki86]

I'm looking into building an ESP32 Bluetooth microphone for my hearing impaired stepdaughter. The basics would be the ESP32, one or two microphones and a pair of Bluetooth earbuds or headphones. The ESP32 will be doing the necessary audio processing and transmitting it to the headphones via the A2DP protocol.

She can hear certain frequencies, depending on the amplification. So, what I want to do is to have the ability to adjust the amplification of a range of frequencies, while not amplifying what she can already hear to prevent headaches.

Can this be done with this library? If so, can a sample of code be posted to show it? I looked through every example, but everything seems to be for visualization on the plotter or on a screen.
