CC: Jukebox

CC: Jukebox lets ComputerCraft computers broadcast music from a playing jukebox to remote CC speakers.

Listeners join at the current point in the song. Removing the disc stops playback.

• Includes a ready-to-use jukebox_radio program
• Broadcast to multiple receiving computers
• Designed for server-side installation or singleplayer

Run jukebox_radio broadcast on a computer beside the jukebox, then jukebox_radio receive <sender-ID> on a computer with a speaker. Both computers need modems.

Lua API

Find a connected jukebox with peripheral.find("jukebox"). Direct connections and wired modem networks are supported.

• hasRecord() – checks whether a disc is inserted.
• isPlaying() – checks whether the jukebox is playing
• getRecord() – returns the disc’s item ID, sound ID, title, duration, playback state, and elapsed time
• readAudio(cursor?, token?) – reads audio chunks from the current playback position

readAudio() returns a table with a status: loading, audio, waiting, stopped, ended, or error. Audio results include audio, token, cursor, and next. Pass next and token into the following call to continue smoothly.

Audio is a binary string of 48 kHz mono PCM bytes. Convert each byte with audio:byte(i) - 128 before passing the sample table to speaker.playAudio(). Custom programs can relay these chunks over Rednet.
