As far as I know you are correct. Mozilla released the Audio Data API and produced a number of demos based on that. A W3C group was formed to work on Web Audio standardisation and in that group Google announced the work on their API. Mozilla then followed with a "Media Processing" API: http://robert.ocallahan.org/2011/06/media-processing_15.html http://robert.ocallahan.org/2011/06/media-processing_15.html It's possible that person you are responding to is thinking of that.
