Electronics giant Philips has purchased the patent for an audio compression algorithm from an Aalborg University post-doctoral student for an undisclosed sum. Mads Græsbøll Christensen's algorithm enables digital devices such as MP3 players, DVD players and mobile phones to produce more realistic musical sounds - especially percussive sounds - than is possible with the algorithms that are currently in use.
 
Steven Van de Par of Philips Research labs in Eindhoven comments that previous audio compression algorithms have been prone to distorting sudden sounds, called "transients", such as the sound made by castanets. The new compression algorithm can make these transients sound much more lifelike.
 
MP3, DVD and mobile phones are all areas where Philips can use its newly acquired patent, but the company is not giving any details of what its plans may be. "The introduction of products with improved means of handling transients depends on how the development of standardisation proceeds, but we see potential in the technology," says Van de Par.
