Detailed Description

Prepared source-filter cross-synthesis for coherent one-sided frames.

The carrier supplies phase and fine spectral structure. Separate cepstral envelopes are estimated with CepstralEnvelopeAnalyzerT; the modulator envelope replaces the carrier envelope in the log-magnitude domain. This is deliberately not raw magnitude/phase interpolation (SpectralMorphT).
