ambi_reduced_decode_fft2

ambi_reduced_decode_fft2 calculates a reduced set of HRTF spectra for Ambisonic binaural decoding by forming a decoder matrix from real and phantom loudspeaker positions, computing its pseudoinverse, and applying its columns to left-ear HRIRs followed by a real FFT. A key usage detail is that calc_pinv starts matrix encoding, while calc_reduced with an Ambisonic channel index generates that channel’s reduced decoder data.
