Arduino Audio Input : 8 Steps (with Pictures) - Instructables
https://www.instructables.com/Arduino-Audio-Input/
You can see from fig 2 (zoomed in view of fig 1) that the Arduino is taking one sample every 125us from A0. We can calculate the sampling rate as follows: sampling rate = 1/125us = 1/0.000125s = 8000hz To give you a point of comparison, normal audio sampling rates are at least 40kHz. If a sampling rate of 8kHz or less is good enough for your purposes then you …

Audio Hacker: Arduino shield for realtime audio processing

An Arduino is fast enough to sample an audio input with the ADC and recreate the signal on the output DAC at a rate of 44.1 kHz with 12-bits of resolution. However, when recording the sampled audio to SRAM, the sample rate is limited to about 22 kHz because it takes extra time to communicate with the memory chips.
ARDUINODSP - AMANDA GHASSAEI

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 …

As a follow up to the Arduino Audio Input tutorialthat I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino's analog input and determines the frequency. The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes. I've also turned the LED attached to pin 13 into a clipping indicator, so you know if you need to adjust your signal's …

arduino uno - How do I know the sampling frequency ...
https://arduino.stackexchange.com/questions/699/how-do-i-know-the-sampling-frequency
For a 16 MHz Arduino the ADC clock is set to 16 MHz/128 = 125 KHz. Each conversion in AVR takes 13 ADC clocks so 125 KHz /13 = 9615 Hz. That is the maximum possible sampling rate, but the actual sampling rate in your application depends on the interval between successive conversions calls.

This is a problem if we want to measure the audio signal with one of the Arduino’s analog inputs because the Arduino can only measure voltages between 0 and 5V. If we tried to measure the negative voltages in the signal from fig 3, the Arduino would read only 0V and we would end upclipping the bottom of the signal. In this Instructable I’ll show you how you can …

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. Pin 11 is used as PWM audio output connected via a RLC Filter to the audio output jack.
