The HODs of the various National Bodies presented

M15911	General/All Comment on the Unified Speech and Audio Coding Exploration Activity	Wen Gao on behalf of the Chinese NB
m15879	Comment on the Unified Speech and Audio Coding Activity	Mauri Väänänen on behalf of Finnish National Body
m15914	Comment on the Unified Speech and Audio Coding Activity	Pierrick Philippe on behalf of the French National Body

Prof. Huang, the Chinese HOD, noted that their comment raises two broad issues

• 
  In the Core Experiment process, testing all 9 operating points may be too burdensome.
  
• 
  Core Experiments should be conducted on a single source code base for encoder and decoder.
  

Chair noted that if the encoder source is mandated for CEs, then in his opinion this runs counter to the Audio CE methodology in force at the time of the Call. Ralf Geiger, FhG, noted that there might be a danger in using sub-optimal source code to select CE technology that might not be needed relative to a more optimized code base.

Justin Ridge, Finish HOD, noted that a CE is credible if both the encoder and decoder source code are available, and the successful CEs should provide their new coding tool as optimal source code. Pierrick Philippe, France Telecom R&D, proposed that RM0 be made available as an object module which CE proponents can use as a toolbox for their CE proposal.

Prof. Huang, the Chinese HOD, reiterated its position that a source code framework for CEs would facilitate the widest collaboration.
