OS X :: Audio File Randomly Starts Playing?

I have an iMac - running Snow Leopard:

10.6.2
2.4gh intel core 2 duo
1gb 677 mhz ddr2 sdram

256gb free disk space

Randomly throughout the day, an audio file will start to play and will repeat until I shut the machine down.

The file starts by saying: Mikano (best guess), two seconds later I hear a gong followed by some Asian music.

The file is not in my iTunes.

I may or may not have iTunes open (and if open, the file continues to play when I close iTunes).


I may or may not have Safari open (and if open, the file continues to play when I close Safari).

I will close all applications and the music continues to play.
