| hi philipp -
yes i think it is because martin used the zak feature. i never used it,
but i think you can straightforward change it to direct audio output.
for instance, in the UDO "ambi2d_encode_3" (example 05B11 in
https://flossmanual.csound.com/sound-modification/panning-and-spatialization#ambisonics2d),
you can change
opcode ambi2D_encode_3, 0, ak
asnd,kaz xin
kaz = $M_PI*kaz/180
zawm asnd,0
zawm cos(kaz)*asnd,1 ;a11
zawm sin(kaz)*asnd,2 ;a12
zawm cos(2*kaz)*asnd,3 ;a21
zawm sin(2*kaz)*asnd,4 ;a22
zawm cos(3*kaz)*asnd,5 ;a31
zawm sin(3*kaz)*asnd,6 ;a32
endop
to
opcode ambi2D_encode_3, aaaaaaa, ak
asnd,kaz xin
kaz = $M_PI*kaz/180
a1 = asnd
a2 = cos(kaz)*asnd
a3 = sin(kaz)*asnd
a4 = cos(2*kaz)*asnd
a5 = sin(2*kaz)*asnd
a6 = cos(3*kaz)*asnd
a7 = sin(3*kaz)*asnd
endop
i hope it works; i leave the test to you ...
