template<typename Func >

output_type MayaFlux::Yantra::SpectralTransformer< InputType, OutputType >::apply_per_channel ( input_type &  input, Func &&  func  )

inlineprivate

Extracts per-channel spans, applies func to each, and reconstructs.

Template Parameters

Func	Callable matching std::vector<double>(std::span<double>)

In-place: results are written back into the channel spans of input before reconstruction, leaving no second allocation of channel data live at the same time. Out-of-place: results land in m_working_buffer; the original channel data in input is not touched.
