Functions
std::optional< std::vector< float > >	pulp::audio::detail::finish_impulse_response (std::vector< float > mono, double file_sr, double session_sr, const ImpulseResponseLoadOptions &opts)
	The post-decode half of the IR pipeline, shared by every entry point: resample the mono buffer from file_sr to session_sr, drop the resampler's leading group delay, clamp to the cap, reject non-finite content, and (optionally) unit-energy normalize.
std::optional< std::vector< float > >	pulp::audio::read_impulse_response_pcm (const float *samples, std::size_t frames, std::uint32_t channels, double src_rate, double target_sample_rate, const ImpulseResponseLoadOptions &opts={})
	Read already-decoded PCM → mono → resampled to target_sample_rate → (optionally) unit-energy normalized.
std::optional< std::vector< float > >	pulp::audio::read_impulse_response (const std::string &path, double target_sample_rate, const ImpulseResponseLoadOptions &opts={})
	Read an IR file → mono → resampled to target_sample_rate → (optionally) unit-energy normalized.
