Abstract: A method of and apparatus for time compression and changing the readout speed of a delta modulation encoded audio signal. The encoded audio signal has portions selectively deleted therefrom in accordance with detected zero crossovers of the same sign which occur in a predetermined timing sequence. The encoded audio signal which has had portions selectively deleted therefrom is decoded, with the undeleted decoded portions being joined. The undeleted portions have the same gain factor where joined, thereby eliminating step transients.

Abstract: A system for writing data to a disk array includes a cache memory coupled to the disk array for storing data indicative of locations on the disk array and parity blocks associated with parity groups including the locations. Each of the parity blocks includes an identifier indicative of locations within a particular parity group which are protected by the parity data. Write logic reads the identifier from the parity block, and based thereon, determines whether a disk location is not protected by the parity data. The write logic also writes to the location and updates the parity data and the identifier associated with the parity block to include the location of the data block to indicate that the location is protected.
