If FLAC doesn't store the 'fmt ' chunk verbatim then it doesn't handle it. At the moment people can use WavPack (which does store the 'fmt ' chunk), and in the long term we could register an ID for a METADATA_BLOCK_APPLICATION. If you are interested in the ".amb" spec then the non-standard GUIDs are described at: http://dream.cs.bath.ac.uk/researchdev/wave-ex/bformat.html and the rest of the description is at: http://www.ambisonia.com/Members/mleese/file-format-for-b-format/ There are currently over 100 pieces in the ".amb" format available for free download. Most are full-sphere surround sound.
