Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

The construction of a target compound from simpler starting materials through a planned sequence of reactions. In The Logic of Chemical Synthesis, Corey and Cheng set out the discipline of designing such routes, reasoning backward from the target molecule to available precursors, an approach called retrosynthetic analysis. The referent is a molecule and the unit is a reaction pathway; what is synthesised is matter, assembled bond by bond in a flask. This meaning shares only the word with the others: nothing here is an argument being resolved or a signal being generated, and success is judged by yield and purity, not by agreement or audibility.[1]
The moment in a dialectic where a thesis and its antithesis are resolved into a higher unity that both preserves and overcomes them, the movement Hegel calls Aufhebung. The tidy three-step label thesis, antithesis, synthesis is routinely credited to Hegel, but Hegel himself rarely used those terms; as Mueller documents, the formula was popularised by later expositors, notably Chalybaus, and reads a schema back onto Hegel that he did not name. The referent is a movement of concepts in the Science of Logic, not a substance or a signal. Here synthesis names the outcome of opposed ideas meeting, which is a different construct from combining reagents or generating sound.[2][3]
The electronic generation of sound by building up a waveform rather than recording one. Chowning's 1973 method, frequency modulation synthesis, produces rich, time-varying spectra by using one oscillator to modulate the frequency of another, a technique that later drove the Yamaha DX7. Other approaches sum sine waves (additive synthesis) or carve a raw waveform with filters (subtractive synthesis). The referent is an audio signal and the unit is a generated waveform; what is synthesised is sound, made from oscillators. This meaning meets the others only at the word: a synthesised tone is not a synthesised molecule, a resolved argument, or a pooled estimate.[4]
The quantitative integration of findings across many separate studies. Glass coined meta-analysis in 1976 for the statistical analysis of a large collection of results from individual studies, pooling their effect sizes to estimate an overall effect and to examine what moderates it. The referent is a body of published research and the unit is the effect size drawn from each study; what is synthesised is evidence, combined across investigations. This is research synthesis, not chemical, dialectical, or sonic synthesis: the inputs are prior studies and the output is a summary statistic carrying its own uncertainty.[5]
