Method for the joining, or mixing-in or fade-in of two audio digital signal segments, free of interfering signals

Claim 1

In a method for the joining, mixing-in, fading-in and fading-out of first and second audio program segments which are stored on respective magnetic tape sections as digitally coded audio signals including error correction codes, along with assigned time codes, in which the digitally coded audio sequences and time codes are read and monitored to determine interference-free locations which may be joined as a single edit location, the improvement therein comprising the steps of: reading each of the digitally coded audio signals and the assigned time codes of the first and second audio program segments from the respective magnetic tape sections; converting the digitally coded audio signals of the first audio program signal segment into first code word sequenced and storing the same along with the assigned time codes; converting the digitally coded audio signal of the second audio program signal segment into second code word sequence and storing the same along with their associated time codes; circulating the stored first and second code word sequences, along with their time codes, relative to one another while monitoring the same by reading and converting the same into audio signals, until an interference-free location of comparable program is determined for each of the audio program segments; and joining the second code word sequence to the first code word sequence at a common edit location identified by the respective time codes of the interference-free locations.
