android microphone audio forwarding pulseaudio

audiosource's Introduction

Audio Source

Audio Source forwards Android microphone audio input to the PulseAudio daemon through ADB, so you can use your Android device as a USB microphone.

Requirements

Device with at least Android 4.0 (API level 14), but fully tested only on Android 10 (API level 29) so your mileage may vary.
GNU/Linux machine with:
- Android SDK Platform Tools (requires adb in PATH).
- PulseAudio (requires pactl in PATH).
- Python 3 (requires python3 in PATH).

Usage

Install the Audio Source APK by following the build instructions, or from the releases.
Enable Android Debug Bridge (ADB) from the Developer options and connect the device to your computer.
Run ./audiosource run to start Audio Source and forward the audio automatically. (You may have to grant the permission to record audio in Android.)
Run ./audiosource volume LEVEL, to set the PulseAudio source volume to LEVEL, for instance 200% (you will likely need to set the volume higher than 100%).

Build and install

Run ./gradlew tasks to list the available commands.

Debug

$ ./audiosource build
$ ./audiosource install

Release

Generate a Java KeyStore:

$ keytool -keystore /home/user/android.jks -genkey -alias release \
       -keyalg RSA -keysize 2048 -validity 30000

Create keystore.properties in the project root directory containing:

storeFile=/home/user/android.jks
storePassword=STORE_PASS
keyAlias=release
keyPassword=KEY_PASS

Build and install:

$ export AUDIOSOURCE_PROFILE=release
$ ./audiosource build
$ ./audiosource install

audiosource's Issues

Audio skipping

Audio seems to come and go and the sound is just non-stop skipping, like so

Consider Updating Shebang Line for Better Portability

I Suggest replacing shebang line from #!/bin/bash to #!/usr/bin/env bash for improved portability across Unix-like systems.

Need clarification on instructions

The instructions say to run ./audiosource run to launch the app, but I have no idea what this means. Is this via ADB on my computer, on my phone via Termux, or something else? I tried running it from termux and it said I didn't have permissions even though i just granted them to termux. I tried running it from my drawer and it popped up a permissions window before instantly exiting
