The audio input signal is connected via a 10uF capacitor to the the analog input 1 of the Arduino Board. Two resistors and a trimmpot are adding an DC offset to the audiosignal . A potentiometer connected to analog input 0 will be used to control the audio effects.

this spectrum analyzer is made of two parts: the processing part that does a fast fourier transformation (fft) on the stereo mix of the computer and splits the audio into 16 frequency bands and finds their amplitudes and sends this data to the arduino; then there is the arduino part that takes the data from the processing half and lights up the …

Here is another instructable describing how to set up a simple audio out circuit with Arduino. digital recorder- with the addition of an SD card of course (the Arduino has very limited memory by itself), this opens up the possibility of looping large samples and doing lots of other digital manipulations to pieces of stored audio The circuits and code provided here are compatible …

But, the Arduino analog-to-digital converter reads from 0-1023. So with the internal reference set to 5V, you will read ~511 (not 127) with 2.5V applied. With silence (and the 2.5V offset), you will read ~511.

Martin documents his experimentation with Arduino and realtime audio signal processing and generation – The first set of examples alter an incoming audio signal and put it back to an audio output. We achieve effects like Reverb, Phasor, Flanger or Ringmodulator.

Audio Hacker: Arduino shield for realtime audio processing
https://nootropicdesign.com/audio-hacker/
The Audio Hacker shield for Arduino allows you to perform realtime digital signal processing. Record audio samples into memory and play them back. Mix samples, manipulate audio, build audio effects, or synthesize entirely new sounds. All with Arduino programming! High quality 12-bit ADC and 12-bit DAC.
ARDUINODSP - AMANDA GHASSAEI
https://amandaghassaei.com/projects/arduinodsp/
This Arduino-powered vocal effects box pitch shifts and distorts incoming audio signals to produce a wide variety of vocal effects. It samples an incoming microphone signal at a rate of about 40 kHz, manipulates the audio digitally, and then outputs 8 bit audio at 40 kHz through an R2R resistor ladder DAC. To minimize the amount of computation required by the Arduino, I …
