My experience with AndroidMic

[shahriarkabir-sagor]

I was searching for an open-source application that would let me use my smartphone as a microphone for my PC. Although there are several apps that allow my phone to function as a webcam, I specifically needed the microphone feature, since the other apps kept the camera on and drained my phone’s battery quickly. After reading the README, I realized that I needed to build the app myself. I mistakenly assumed that the repository contained only source files and forgot to check the release page.

Without having Rust and Android Studio installed, I forked the project and attempted to set up an automated workflow to build the app with every push or pull request. Keep in mind, I only have basic development knowledge and no experience with CI/CD or Rust builds. After much trial and error (and some help from AI), I managed to create a workflow that built binaries for Android, Linux, and Windows.

When I ran the Windows application and the Android APK, the tool didn’t work as expected. I assumed that the PC app would recognize my device as a microphone and allow it to serve as an audio input source. Instead, I encountered an error message stating, "The requested stream configuration is not supported by the device." At that point, I checked the release page again and found the 2.0.0 release. Although it worked to some degree, the audio lag was significant and very noticeable. I also looked for a social page to contact the developer, but I couldn’t find any.

Hi, yes this is the place you can contact us. The app in the release page is outdated. We've rewritten the app in another programming language since then. You can only build it locally right now. We'll try to make a new downloadable release this year.

Regarding your question of "The requested stream configuration is not supported by the device."
On the desktop app, click advanced and choose a combination of 44100 sample rate, mono channel and i24 audio format. This is the most common setting. If it doesn't work, try 48000 sample rate. On the mobile app, make sure to configure it to use the same settings.

48000 mono i16 is working for me.

After the latest commit, I don't know why, but I feel like the sound quality has improved. It's much clearer now. Could you please make an improvement so that, instead of just outputting the sound, it can be used as a microphone input? I'm planning to test it to see if it works.

Hi in this case you would need another software to create a virtual microphone device, which creates an input and output device on the system, and routes the output audio to the input audio, and then you can use the input device as microphone. The solution very much depends on your system OS.

Thanks. I will look for such application. I am using windows 11. Got any recommendation?

There're Virtual Audio Cable and VB-Audio. I think they both provide some free options but I was using VB-Audio when I tested on Windows.
