Detailed Description

template<typename Allocator = std::allocator<uint8_t>>
struct audio_tools::fft_state< Allocator >

FFT state management structure with custom allocator support.

Manages FFT operations through an abstract AudioFFTBase driver interface and maintains temporary buffers for real and imaginary components. The structure is templated to support custom memory allocators for embedded systems or specialized memory management requirements.

Template Parameters

Allocator

Custom allocator type (defaults to std::allocator<uint8_t>)
