Abstract
When a portion of an original audio track is unsatisfactory, alternate portions are searched for using phonetic matching within phonetically indexed alternate files. The alternates may correspond to recordings captured in a different take from the original where timecode matching is unavailable. An editor may preview one or more candidate alternates and select a preferred one to be used to replace the original. A media editing application, such as a digital audio workstation, automatically aligns and matches the preferred alternative to the original using waveform matching and optional gain matching.
