Usage: ambi_converter input_file output_file input_convention output_convention



input_convention and output convention must be an integer number in [0,5]

the following conventions are supported:

0 : ACN-SN3D

1 : ACN-N3D

2 : FuMa-MaxN

3 : FuMa-FuMa

4 : SID-SN3D

5 : SID-N3D



Either the input or the output convention must always be ACN-SN3D!
