Add a Microphone API

[Grabli66]

Please, add the posibility to record audio from microphone.
It's needed for creating music applications, such as i do :)

@Grabli66 if you wish, i can write a simple c++ signal mic module for you in the meantime using SDL 2.0.5 or greater.

dummy_audiostream.zip

I am just using a mic for an unrelated purpose. As you can see in the code, I really do not care about usability other than my use case. I would modify the code for your use case

https://forums.libsdl.org/viewtopic.php?p=51881

either way, I would never expect this code to be committed because it is only meant for me.

[Grabli66]

Thanks.
But I don't want temporary solution.
I'll will wait.

I second the request for this functionality, in my case for purposes of streaming the audio in a VR game to other players over the network (which would obviously require some kind of realtime audio codec for low latency/bandwidth transmission).

Hi - first time poster.
I am growing really fond of GODOT for making 2d games!

I have a great idea for a small game series that utlize audioinput like "scream hero". Unfortunately I just saw that there is no support for microphone input.

I would love to get that feature!

@hungrymonkey I just gave your link a quick look! How easy is it to implement?
Do I need to make my own branch of the GODOT 3 engine or can it interact with the stable version?

[hungrymonkey]

@mad-tzar

its currently not registered into GDScript. But that is easy too.

copy the module over and compile basically

the audiostream is currently crappy since i do both memory allocation and block the audio stream.

The mic is ok, it is basically an event base mic. a few lines of code can change it into a float base

@DEF7 well, i was kinda working on that. that is the reason why i added an mic.

I suggest you look into godot Server

Very happy to see this development. Working on dev of endangered-world-languages learning applications for non-profit educational use. Godot will be the perfect engine for this work once mic support is implemented. I have not ventured far into learning C languages yet and was hoping would not have to.

Thank you for your SDL mic code, @hungrymonkey ! I adapted it for a small project of mine and it worked very well.

[hungrymonkey]

@fahrstuhl sure, no problem. I actually created a lockless version for the dummy audiostream.

I am currently trying to refactor voip then ask reduz for input. it is in process.

[zvoislav]

Hi,
I really need a audio record feature. Can you @fahrstuhl or somebody else explain me how to implement this SDL module and how to use it.
Thank you in advanced.

[hungrymonkey]

I already provided a link

https://github.com/godotengine/godot/files/1515081/dummy_audiostream.zip

its just not registered to gdscript. You just have to add it to my modules.

If you wish, you can take a look at the official mic

Fixed by #19106.

[Colorfingers]

Please add microphone support... this is pretty much a standard feature on all platforms. Thank you...

[Calinou]

@Colorfingers This was implemented in #19106 and will be available in 3.1 😃

[Colorfingers]

Sweet, thanks!
