# 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
1. Install the Audio Source APK by following the [build
instructions](#build-and-install), or from the
[releases](https://github.com/gdzx/audiosource/releases).
2. Enable *Android Debug Bridge* (ADB) from the *Developer options* and connect
the device to your computer.
3. Run `./audiosource run` to start Audio Source and forward the audio
automatically. (You may have to grant the permission to record audio in
Android.)
4. 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
```shell
$ ./audiosource build
$ ./audiosource install
```
### Release
1. Generate a Java KeyStore:
```shell
$ keytool -keystore /home/user/android.jks -genkey -alias release \
-keyalg RSA -keysize 2048 -validity 30000
```
2. Create `keystore.properties` in the project root directory containing:
```
storeFile=/home/user/android.jks
storePassword=STORE_PASS
keyAlias=release
keyPassword=KEY_PASS
```
3. Build and install:
```shell
$ export AUDIOSOURCE_PROFILE=release
$ ./audiosource build
$ ./audiosource install
```
