Wireless sound from one arduino to another

I want to transmit wireless sound from one Arduino to another (microphone and speaker wise)

Specifications:
Distance: A few meters (I was thinking on using RF)
Quality: It doesn't matter
Sound comes from: Microphone (one end)
Sound goes to: Speaker (other end)

Is it possible? Any tips thanks.

What distance?
What quality?
Where does the sound data come from?
How will you convert the data back to sound at the other end?
Why can't you use a $20 wireless microphone?

It doesn't matter i just want to transmit and receive sound

Because it's no fun :stuck_out_tongue:

I need to pass throw walls and light doesn't do that =(

Any other details?

Two nRF24L01+'s - can drive these fast with SPI if disable the packet-acknoledgement
system. Not trivial though.

My advice is to send it through a wire first so you get the "sound" part working.

Then remove the wire to get the "wireless" part.

ok, but how can i capture the sound?
Is there a schematic for it?

A microphone and preamplifier comes in handy. Google will provide circuits.

This is by no means a trivial project.
You will need some kind of audio amplifer which also provides a Dc offset so that the microphone output
falls within the range of the Arduinos A/D converter.
You will also need some kind of simple audio codec to convert the sampled audio into a digital bit stream to feed to the radio.
At the receiving end you will have to do the reverse, and then somehow recover the audio and feed it to an audio amplifier and then a speaker.
Hope you are an experianced Arduino programmer.

Thank you guys, i was thinking on using a sound sensor, will it work to get the sound?

Anyone, please?

What sound sensor.
A lot of them are just envelope detectors that will not record the waveform of the sound.
Look here for a circuit of how to get sound into an arduino:-
