Member Data Documentation

fft_size

int pulp::signal::SpectralEnvelopeShifterConfig::fft_size = 2048

max_gain_db

float pulp::signal::SpectralEnvelopeShifterConfig::max_gain_db = 60.0f

Finite, nonnegative gain clamp for the applied correction, in dB (safety bound for degenerate envelopes on sparse spectra).

order

int pulp::signal::SpectralEnvelopeShifterConfig::order = 0

Cepstral cutoff (quefrency bins kept).

Smaller = smoother envelope. Defaulted from the frame geometry when <= 0.

true_envelope_iterations

int pulp::signal::SpectralEnvelopeShifterConfig::true_envelope_iterations = 3

True-envelope refinement passes (0 = plain liftering).

Each pass costs two FFTs per frame.
