1.- UDP audio Chat. WiFi. Send sound over UDP.
Through this extension we can send audio from one mobile to another, using UDP. WiFi.
- Blocks.
- Example:
p299J_Voz_UDP.aia (12.1 KB)
- Designer.
- Blocks.
2.- Send and receive audio to the same device.
To do the first test we run the application (it works in MIT Companion). We get the IP of the device, in my case: 192.168.1.2
We write that IP in "To IP". We establish the same port to send and receive, in this case: 4444
We activate the Microphone and the Speaker. We speak in front of the mobile and we must listen to our voice.
To avoid sound feedback it is advisable to use an earphone.
In this example the application is sending and receiving the sound.
3.- Chat with two mobiles.
4.- Broadcast.
5.- Credits.

Cool! But is there a way to use a mp3 file as input instead of microphone? I'd like to do something like phone-bot for my home
The easiest answer would be to send the .mp3 file
send mp3 as text and then playback it at remote device?
One idea would be to convert the file to Base64 and send it using UDP, I haven't tried it with large files.
these files wont be large. just some tts speech
Try
I haven't tried it, but maybe opening the port of a local network (NAT) can be achieved.
I did it
125kb file is too large even when at base64 (it isnt sending)
edit: 64kb is still too big
what did you do to achieve this?
ok, i interpreted your "I did it" as success
Another idea would be to install an FTP server on a PC.
