volctl

A simple Java library providing access to audio volume control on Windows and Linux.

The library uses native C++ code to directly access the relevant system APIs, there are no further dependencies.

Note: This project is still maintained and will be updated if needed. As this library's scope is very limited and there are no statically-linked dependencies, updates are only required if any issues are reported.

Compatibility

This library is compatible with Java 1.8+.

Usage

Example

Kotlin

val volumeControl = VolumeControl()
// Gets the current master audio volume
val value: Int = volumeControl.volume
// Sets the current master audio volume to 82%
volumeControl.volume = 82

Java

VolumeControl volumeControl = new VolumeControl();
// Gets the current master audio volume
int value = volumeControl.getVolume();
// Sets the current master audio volume to 82%
volumeControl.setVolume(82);

Gradle

Kotlin DSL

build.gradle.kts

dependencies {
    // ...
    implementation("com.github.bjoernpetersen:volctl:${Lib.VOLCTL}")
    // or
    implementation(
        group = "com.github.bjoernpetersen",
        name = "volctl",
        version = Lib.VOLCTL)
}

Groovy DSL

build.gradle

dependencies {
    // ...
    implementation 'com.github.bjoernpetersen:volctl:$volctlVersion'
}

Maven

pom.xml

<dependency>
    <groupId>com.github.bjoernpetersen</groupId>
    <artifactId>volctl</artifactId>
    <version>${volctl.version}</version>
</dependency>

Building

Gradle is used to build the project.

Before packaging, you'll need to generate the header files and compile the native library:

./gradlew buildNative

Note that this requires CMake and a C++ toolchain to be installed. Only the native library for the current platform will be built.
