Little Player is a very small application, only 12 Kbyte on your HD that can read and play AIFF and AIFC files (Audio Interchange File Format) directly from disk without loading them in RAM.
So, in a very small RAM partition (128 Kbyte), you can play with excellent quality very large files (some megabyte too).
Works well also in background while you are using some other program, so using your usual program you can listen to music, without performance degradation and using a very small memory partition.
