spectral_processor Struct Reference

spectral processor keeps the values that move through the subsystem: config, forward, inverse, pitch_hz. Some members are pointers into caller- or subsystem-owned memory, so lifetime follows the API that populated them rather than the struct copy itself. More...

Detailed Description

spectral processor keeps the values that move through the subsystem: config, forward, inverse, pitch_hz. Some members are pointers into caller- or subsystem-owned memory, so lifetime follows the API that populated them rather than the struct copy itself.
