The Render name misleading as it did not do the same thing as normal Synth.Render, because it disregarded time limits. Conceptually, as the function modifies the state of the synth, it would be better to be synth.Fill(audioBuffer), but we cannot define methods on interfaces; therefore, it is audioBuffer.Fill(synth) now.
