Open Best Audio Player
Open Best Audio Player is probably the best audio player in the sense that it does everything for you including finding audio files on your hard drive, choosing which one to play and how, it even listens to the files for you.
It handles a few file formats such as .wav and .mp3 and can play up to five of them at the same time.
It has no controls because there is no need for them, just run the software and enjoy.
It's called "open" of course because it's open source.
The previous version from two years ago was using Beads with an bugged mp3 library and had huge memory leaks, but it was recently updated and it seems the leaks are gone now.
The idea for this was inspired by another little thing called "SoundRaider" that seems to be hard to find nowadays so here it is.
