Detailed Description

template<typename SampleType = float, std::size_t MaxFftSize = 4096, std::size_t MaxChannels = 8>
class pulp::signal::OnsetNoveltyFrontEndT< SampleType, MaxFftSize, MaxChannels >

Fixed-capacity streaming novelty analysis.

This does not publish onset markers or confidence because those require a global offline postpass. Ownership, preparation, cadence, and callback rules match ChromaFrontEndT.
