    Delius will accept digital data at 44.1kS/s from your CD player and interpolate the 16 bits, giving your CD collection a new lease of life. Delius will also convert 24 bit 96kS/s data from DVD players, revealing the increased depth and spaciousness inherent in the more complex source information.
