Frequently asked questions

How do I make my first music speaker?
You need to craft an Ethereal Record with your chosen song URL, then place a Speaker block powered by rotational force from a Create contraption. Point the speaker in the direction you want sound to come from, and it will play the music from that record.
Do I need ffmpeg and ytdlp to use this mod?
Yes, the mod uses these tools to fetch and convert audio files. The mod will ask your permission before downloading them to your computer, or you can manually place your own versions in the designated folder if you prefer.
How much rotational power does a speaker need to play music?
Speakers require rotational force from Create's power system to operate, but the exact power requirements depend on your setup. As long as your contraption is spinning the speaker's connected shaft, it should play audio.
Can speakers move on trains or elevators?
Yes, this is one of the mod's key features—speakers work perfectly on moving contraptions like trains, elevators, and other Create mechanisms. The music will continue playing as the speaker travels with your build.
Why is there no sound coming from my speaker?
Check that your speaker has rotational power connected, the Ethereal Record is placed correctly in the speaker, and the audio URL was processed successfully. If audio still won't play, see the troubleshooting guide for common issues like network problems or unsupported formats.
Does this mod work with other Minecraft audio mods?
Yes, Create Harmonics routes audio through Minecraft's standard sound system, so it's designed to work alongside other audio mods without conflicts.
Can I use my own audio files instead of online links?
Yes, you can place custom audio files in the appropriate mod folder and reference them as local files instead of URLs. See the custom audio guide for the correct file format and folder location.
Will using this mod slow down my game or server?
No, because audio streams directly from the internet to your client, not through the server. This keeps server load minimal, though your internet connection speed may affect how quickly songs load and start playing.
