Talk:FreeFieldDirectivityTF

changes:

• TuningFrequency:LongName: not required, because TuningFrequency is always frequency.
• TuningFrequency:Unit: not required because TuningFrequency should be in Hz (IS) always.
• ListenerView/Up: added because required to define the orientation of the microphone array
• SourcePosition:Definition renamed to SourcePosition:Reference because they provide the narrative description of the spatial reference. SourceView/Up:Definition: the same.
• EmitterMidiNote: renamed to MIDINote because we don't use emitters anymore.
• EmitterDescription: renamed to MIDINoteDescription because it describes a note.
• GLOBAL:MusicianPosition: renamed to GLOBAL:Musician

To be discussed:

• MIDINote (and MIDINoteDescription) or Note, Note:Long, Note:Unit = MIDI, NoteDescription ??? The latter has the advantage of being more general. But more complex...
• Conventions name: if we want to keep it simple, we could ignore the room (the usual case when talking about directivity). Then, the convention could be called FreeFieldDirectivityX, with X={TF|FIR}. Note that I skipped the "MusicalInstrument" because this is limiting and we consider directivity of loudspeakers and singers already now, i.e., more than just instruments.
