Lavalink

A standalone audio sending node based on Lavaplayer and Koe. Allows for sending audio without it ever reaching any of your shards.

Being used in production by FredBoat, Dyno, LewdBot, and more.

A basic example bot is available.

Features

• Powered by Lavaplayer
• Minimal CPU/memory footprint
• Twitch/YouTube stream support
• Event system
• Seeking
• Volume control
• REST API for resolving Lavaplayer tracks, controlling players, and more
• Statistics (good for load balancing)
• Basic authentication
• Prometheus metrics
• Docker images
• Plugin support (beta)

Requirements

• Java 11* LTS or newer required.
• OpenJDK or Zulu running on Linux AMD64 is officially supported.

Support for Darwin (Mac), Windows AMD64, and Linux ARM (Raspberry Pi) is provided on a best-effort basis. This is dependent on Lavaplayer's native libraries.

Lavaplayer currently supports following architectures:

Darwin (M1 & Intel), Linux aarch32, Linux aarch64, Linux ARMv7+ 32/64, Linux ARMHF(v6) 32, Linux i386 32, Linux x86 64, Windows i386 32 and Windows x86 64

JDA-NAS(Native Audio Buffer) & the Timescale filter are currently not supported on following architectures:

Linux ARMHF(v6) 32 and Linux aarch32

Support for other JVMs is also best-effort. Periodic CPU utilization stats are prone not to work everywhere.

*Java 11 appears to have some issues with Discord's TLS 1.3. Java 14 has other undiagnosed HTTPS problems. Use Java 13. Docker images have been updated. See #258, #260

Or alternatively, you can create your own client library, following the implementation documentation. Any client libraries marked with Unmaintained have been marked as such as their repositories have not received any commits for at least 1 year since time of checking, however they are listed as they may still support Lavalink, and/or have not needed maintenance, however keep in mind that compatibility and full feature support is not guaranteed.
