Resynthesized

Resynthesized is the past participle of resynthesize and is used as an adjective to describe something that has been synthesized again or reconstructed from its constituent parts. The term combines the prefix re- with synthesize and appears in fields ranging from audio engineering to synthetic biology. In general usage, it implies a re-creation rather than a direct reproduction of the original material.

In audio and music technology, resynthesis is a process that analyzes a sound and constructs a new version from that analysis. Techniques include spectral resynthesis, additive and subtractive synthesis, granular synthesis, and physical modeling. A resynthesized sound may preserve the general envelope or timbre of the source while allowing changes in pitch, duration, or articulation. Resynthesized samples are common in sound design, where a recorded sound is broken down into components and rebuilt to create novel textures or to extend a sound beyond the limits of the original recording.

In speech technology, resynthesized speech or singing refers to an audio signal generated anew by a synthesis engine, often from a phonetic or musical representation. This can be used in text-to-speech systems, voice conversion, or singing synthesis, where the generated voice is resynthesized from models rather than directly recorded utterances.

In synthetic biology, the term can describe a genome, gene, or sequence that has been constructed from chemically synthesized DNA and assembled anew, rather than recovered from a biological source. In each domain, the quality and fidelity of resynthesized material depend on the accuracy of the analysis, synthesis methods, and subsequent processing.
