rand-mp3

Loop random samples of mp3s

A pure java port of Cutups.

Thought I’d have a go at hacking it out with the javaFX mediaplayer because haven’t really done any javaFX or media stuff in java and seemed like an interesting problem.

It only has a dependency on pure java 8/maven (as javaFX is bundled with jdk8).

Given a folder full of music, it will pick a random mp3 and choose a random part of the file to play.
It will then loop a random sized sample from a random position inside the track.

• Pressing r then enter will start playing another random sample from the same file.
• Pressing f then enter will start playing another random sample from a random file.
• Typing quit (or q) then enter will then exit the program.

The main entry point of the program is the Runner class

Build executable jar via standard mvn clean install.

Usage:

java -jar rand-mp3.jar <file-path> <longest possible sample in seconds>

e.g:

java -jar target/rand-mp3-0.0.1-SNAPSHOT.jar "/home/alee/Desktop/Cowboy Bebop/" 4

Limitations:

• Doesn’t record the resulting sound
• Only displays how much of the track was skipped after hitting enter
• Only tested on linux
• Hacked together / code is a bit crappy
