Convert FuMa to Ambix --------------------- ACN-0 = 1.4142 * W (+3.01 dB) ACN-1 = Y ACN-2 = Z ACN-3 = X ------ ACN-4 = 0.8660 * V (-1.25 dB) ACN-5 = 0.8660 * T ACN-6 = R ACN-7 = 0.8660 * S ACN-8 = 0.8660 * U ------ ACN-9 = 0.7906 * Q (-2.04 dB) ACN-10 = 0.7454 * O (-2.55 dB) ACN-11 = 0.8433 * M (-1.48 dB) ACN-12 = K ACN-13 = 0.8433 * L ACN-14 = 0.7454 * N ACN-15 = 0.7906 * P Ambix files should use CAF (Apple's Core Audio Format), but in practice WAVEX is used as well. Convert Ambix to Fuma --------------------- W = 0.7071 * ACN-0 (-3.01 dB) X = ACN-3 Y = ACN-1 Z = ACN-2 ----- R = ACN-6 S = 1.1547 * ACN-7 (+1.25 dB) T = 1.1547 * ACN-5 U = 1.1547 * ACN-8 V = 1.1547 * ACN-4 ----- K = ACN-12 L = 1.1859 * ACN-13 (+1.48 dB) M = 1.1859 * ACN-11 N = 1.3416 * ACN-14 (+2.55 dB) O = 1.3416 * ACN-10 P = 1.2649 * ACN-15 (+2.04 dB) Q = 1.2649 * ACN-9 Ciao, -- FA _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
