SOFAupdateDimensions yields error if EmitterDescription is defined about sofatoolbox HOT 4 CLOSED

Dear Fiete,

could you try:

sofa.GLOBAL_EmitterDescription = 'test';
SOFAupdateDimensions( sofa );

In our API, all global attributes (and EmitterDescription is a global
attribute) need a GLOBAL_ prefix. Without the prefix, the API thinks
that EmitterDescription is a variable and expects a dimension.

Regards,
Piotr

According to

version 0.3 of MultiSpeakerBRIR /uses SOFA 1.0 which reflects the
standard AES69-2015/. According to the AES Standard,
"EmitterDescription", "ListenerDescription", ... are optional fields.
However,

sofa = SOFAgetConventions('MultiSpeakerBRIR');
sofa.EmitterDescription ='test';
SOFAupdateDimensions( sofa );

yields

|Error using SOFAupdateDimensions (line 85) EmitterDescription seems to
be a user-defined variable without a dimension. |

In the AES standard ( http://www.aes.org/publications/standards/search.cfm?docID=99 ), 'EmitterDescription' or 'ListenerDescription' do not appear in the table for global attributes ( p. 16, Table 2 ), but are rather listed in in Table 3 and 4 (p. 17), respectively. How is this related to the current implementation of the API?

Dear Fiete,

that's a little bit tricky:

EmitterDescription is not in the Table with the general attributes (Tab.
2) because it belongs to the object Listener.
EmitterDescription is thus described in Tab. 3, which addresses the
metadata related to the Listener. It is, however, still a global attribute.

In the Matlab/Octave API, EmitterDescription must be encoded as
X.GLOBAL_EmitterDescription (with X as the variable containing the SOFA
structure). In the API, all global attributes must be prefixed by GLOBAL_.

Hope that help,
Piotr
