Small screen to visualize sound (equalizer)

Hello,

I really hope somebody will be able to help me.
I'm making theatrical project where I'm going to need a mask (which will be printed in 3D technology). Instead of lips, it will have a space to attach a small screen that will visualise speaking (everything will be recorded before).
Size of the screen should be around 2''.
I talked with one of my friends and he suggested to use Rapsberry PI with some small screen, but I'm not sure if there are that small ones that would work with it.
The other friend suggested Arduino.

What do you think?
Is there any other easy way to accomplish it? It just has to visualize the speaking, the screen can be even simple LED.

Thank you in advance for any help.

Kind regards.

Hello,

Do you mean something like this on your screen?

This can be done using some scope software that shows the signal from the mic on the screen.

There are many Arduino compatible LCD screens, both character and graphic. I’ve used them often before.

Look for one with a driver built-in. The ones I’ve used as well as one which I am going to recommend, use an SPI interface. These are simpler to hook up and use. Arduino libraries are also available.

I did a quick search on SparkFun. There are other resources, such as the Arduino site and Adafruit.

Here is a graphic LCD...
https://www.sparkfun.com/products/10168

And the tutorial for its use...
https://learn.sparkfun.com/tutorials/graphic-lcd-hookup-guide

Hope this helps!

Yes sir! This is excatly what I would need.
I assume that I need to have some programming knowledge to handle this by myself. But unfortunetely I don't. At all.
Is it possible to connect this screen to some speaker and make it visualise speaking? Everything it has to visualize will be already recorded, it won't be shown live.

I wouldn’t expect an out-of-the box solution to your problem. I might be wrong. To use these displays would require some programming, and more than basic skills at that.

If I were trying to do this, there’d have to be some way of digitizing the sound you want to display. Then, I’d write a program to initialize the display and take the digitized values and display them on the screen. I have an audio envelope follower built for another project which I would use to digitize the audio. More programming.

I hope you find a complete solution.

Can you show us an example of what you call "visualise speaking"?

Maybe a youtube example.

A simple horizontal line of LEDs, dimmed together with amplitude might suffice.

There are many ways to indicate sound. What way do you think sound looks like?

Or maybe you mean lips.

Something like this, starts at 3:46

Hi shanti,
There are videos on the web that show lip/mouth movement.
I would suggest you try to produce the 5 Vowel images on the TFT screem its not any easy task.
Look at the PDF for more information. [has video links]
E
I guess I won't do this by myself but rather find someone who knows what's up.
Any idea how much would it cost to program it?

So far this idea looks the best.
The point is I will have to find someone who is able to program it. Of course not for free.
How portable is it? Won't it be too complicated to stick it into a mask to make it look...smooth?

Thank you all for your answers, I really, like REALLY appraciate it!

Regards.
