1. A method for editing and combining selected portions of digitally encoded audio signals recorded on at least one record medium to form a composite digitally encoded audio signal, comprising the steps of(a) reproducing signals digitally recorded on said at least one record medium to present audible displays of audio signals recorded on said at least one medium,(b) operating in response to said audible displays to designate tentative entry and exit edit point words defining the spatial locations of selected portions of said reproduced signals to be joined in sequence to form said composite signal,(c) storing the tentative edit point words defining said spatial locations,(d) presenting audible displays of selected portions of the audio signals which are proximate to said spatial locations defined by said tentative edit point words,(e) iteratively refining said spatial locations defined by said edit point words in steps of discrete time intervals of decreasing duration by operating in response to repeated audible displays of the selected portions of the audio signals to establish increasingly refined entry and exit edit points,(f) storing the refined edit point words, and(g) switching between audio signals located on said at least one medium at spatial locations defined by said refined edit point words to sequentially join selected portions of said signals at the thus defined spatial locations to thereby form said composite digitally encoded audio signal.
