Playing Recorded Audio on Arduino

Projects General Guidance
1

I was wondering if it is possible to record and play audio on arduino?

2

Most of the time, you will need some additional hardware to play and record audio, much of which can interface with an Arduino in some way to expand the possibilities. Arduino can do some very low-resolution audio things on its own and different models might have better-or-worse capabilities. You'll want to spend a little time looking into sample rate, bit depth, and analog inputs/outputs.

I'm really starting from scratch on this one, so is there any materials or codes you would recommend? Thanks for the help.

4

This could be a good place to start.

5

Cool thanks! Is a buzzer similar to a speaker? Because I have that

6

You could definitely experiment with a speaker.

As you get a deeper understanding, you might want to look into something like the WAV Trigger.

7

Oh my gosh! This is the exact project I want to create! Thanks so much! I will look into this! Thanks!

8

Exact eh? Then all other suggestions are presumably redundant - but I would have recommended the DFPlayer Mini MP3 Player Module.

9

Ok thanks! ill try that too! I am open to more things since the WAV trigger is 60 bucks

10

OK, come back with any queries when you've started working with it.

11

Check out the dfrobot dot com site.

One player costs $5.90.

Considering shipping, I would buy more than just a tiny MP3 player.

12

Ok cool!

13

I WILL LOok into that!

Yes, It is. You will need An SD card and save the audio files inside the arduino in wav format. You have to connect a speaker with the ARduino though an amplifier. Here is a tutorial that you will find helpful.

Here he designed the amp using only one 2N2222 transistor and a resistor. Depending on your need, you can consider TDA2030.

Thanks I will lOok into THAt!

Arduino Uno can only play low quality music and decent quality speech.
An MP3 player run by an Uno can play MP3 or WAV files at full quality.

Arduino Due has the speed to play high quality and an audio quality DAC to do it with. There are other board choices also capable of audio out that have bluetooth built-in, could use bluetooth speakers directly.
