Arduino Realtime Audio Processing
http://interface.khm.de/index.php/lab/interfaces-advanced/arduino-realtime-audio-processing/index.html
Arduino Realtime Audio Processing. This is an experiment to show how some realtime audio processing can be done with the Arduino. The first set of examples alter an incoming audio signal and put it back to an audio output. We achieve effects like …
Arduino / Processing Audio Spectrum Analyzer : 5 Steps ...
https://www.instructables.com/Arduino-Processing-Audio-Spectrum-Analyzer/
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 LEDs on the display …
Arduino Audio Input : 8 Steps (with Pictures) - Instructables
https://www.instructables.com/Arduino-Audio-Input/
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 …

Hi everybody, I'm a beginner with arduino and I need some (a lot) help on a project i'm working on: I think about creating a realtime audio processing device with arduino connected to speaker (I have 3ohms/55W speaker). It shall be able to analyse a simple sound (for example: if somebody plays a music note) and instantaneously play the same sound wave on the speaker.
Realtime audio processing with Arduino - Make:

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 …
