Detailed Description

template<typename SampleType = float>
class pulp::signal::CepstralEnvelopeAnalyzerT< SampleType >

Log-magnitude spectrum to liftered log-envelope.

Input and output contain exactly fft_size / 2 + 1 DC-to-Nyquist bins. The caller owns conversion to log magnitude and any linear-domain floor policy.

Rejected input leaves log_envelope unchanged.

The conservative input bound proves accepted transforms cannot overflow before output mutation.
