This conventions defines a general convention with FIR-E as DataType (no restrictions but DataType).

GeneralFIR-E is the standardized version of the previously proposed GeneralFIR convention. It extends GeneralFIR by having Emitter as an explicit dimension in the data.

The conventions is defined in AES69-2020 (SOFA 2.0).
