Classes
struct	pulp::signal::SpectralStreamGeometry
	Offline profile 1: symmetric float Hann, unscaled forward FFT, 1/N inverse, local-origin phase, indexed channels, full-overlap startup and squared-window OLA normalization (threshold 1e-9f). More...
struct	pulp::signal::SpectralFrameStamp
struct	pulp::signal::OwnedSpectralStream
	Arrays have exact element counts, with no hidden vector capacity. More...

Functions
SpectralCodecError	pulp::signal::spectral_codec_detail::shape (const SpectralStreamGeometry &g, std::uint64_t count, Shape &s) noexcept
std::uint64_t	pulp::signal::spectral_codec_detail::read (std::span< const std::uint8_t > b, std::size_t p, unsigned n) noexcept
void	pulp::signal::spectral_codec_detail::write (std::uint8_t *b, std::size_t p, std::uint64_t v, unsigned n) noexcept
SpectralCodecError	pulp::signal::spectral_codec_detail::component (std::uint32_t bits, std::uint64_t index, std::uint32_t fft, bool strict) noexcept
SpectralCodecResult< OwnedSpectralStream >	pulp::signal::make_spectral_stream (SpectralStreamGeometry g, std::uint64_t count, std::uint64_t budget=spectral_codec_memory_budget) noexcept
	Allocate an editable owned stream with canonical chronology and zero bins.
SpectralCodecResult< OwnedSpectralStream >	pulp::signal::decode_spectral_stream (std::span< const std::uint8_t > bytes, std::uint64_t budget=spectral_codec_memory_budget) noexcept
	Validate the whole input before allocating; no partial stream is returned.
SpectralCodecResult< EncodedSpectralStream >	pulp::signal::encode_spectral_stream (const OwnedSpectralStream &in, std::uint64_t budget=spectral_codec_memory_budget) noexcept
	Canonicalize signed bin zeros without mutating the caller. Offline only.

Variables
