Help! me please u.u

I would like to learn about the sound in arduino and its possible modification as an effect for musical instruments

Enter "synthesizer" in this site's search bar to see examples of an application of Arduino to music.

real mind not eh found exactly what I'm looking for, it really is my second project with arduino one, to be specific I would like to build an effect for guitar

realy im noob in this

Some people have made guitar effects with the Arduino but you'd have to search.

The regular Arduino doesn't have a DAC (no true analog output), the ADC is only 10-bits and it's a little slow for hi-fi audio, but it might be OK for guitar if you use an external DAC.

The Audacity website has a little Introduction to digital audio. The first thing would be to "pass-through" the audio with an analog-to-digital-to-analog process. After you get that figured-out you can figure-out how to manipulate the digital data for an effect.

DSP (digital signal processing) is an advanced programming topic, but certain effects aren't too complicated.

The Arduino Due has a true DAC, and also a processor that is fast enough to really do things in the audio domain. There are others... some of the STM processors have as well.

Indeed if I have found more about audio manipulation with DUE, but I found a faster answer as mentioned by the colleague @DVDdoug in the direct analogy, in that case I could use my UNO to activate or not certain effects so I directed my search that ended in this code that marks herror

code in question
Tone.ino (211 Bytes)

Like this?

oh yeah @flashko this page it was useful
but, i canot the shield,
so i plan somethings simpler

Simpler? On the site has a scheme and it is simple. I do not know if it is possible simpler and usable.

It is because I understand that he has done everything with the arduino board, being honest I found other types of guitar effects that have more to do with the analog signal than the digital one
i surpose

in this moment i try resolve

Well that project is having you on.
The speciation says

  • Output Stage: 16 bits (2x8bits PWMs running in parallel)

There is no way that the circuit used here is going to produce that. It is a typical false assumption that you can do that. The resistors used are no way accurate enough to produce that resoloution.

No there is nothing you can do that is simpler. The problem is that the Uno is supremely unfit for this sort of application. Only with the addition of extra hardware can you hope to do this.

For a second project you do not have enough knowledge yet to tackle such an advanced project yet. Your only choice is to blindly copy some on else’s projects and hope it works.

I would advise that you get an oscilloscope and learn how to use it, this is vital for any audio project.

"nunca sabemos"

in this comment
yes we totally agree
and the thing about the osiloscope is an excellent proposal ; *

Yes I do.

I wrote this book

Arduino Audio projects.

realy???wwwwooooaaa amazing
per curosity... anyone osoloscope recomentacle and accessible???
per a poor fool noob??
