2 // (src/js/tensor_bindings_audio.cpp): the spectral / FFT core, the complex
3 // helpers and STFT / iSTFT. The rest of the group's bodies live in
4 // native_tensor_audio_b.cpp; the registration table at the bottom of this file
5 // registers both halves.

7 // Complex tensors are FP32 with the bin axis interleaved [re,im,...] — an
8 // (R, 2*C) tensor. fft / ifft have no backward (the adjoint is the other
9 // transform plus a scalar); rfft / irfft and stft / istft do, because their
10 // adjoints carry bin weighting / window + COLA normalisation.
